Frequently asked questions

Yes. 0345 UK-wide numbers are £4.99 a month ex VAT, no setup fee and no contract, added to any paid plan, the same price as 0330. Callers pay the same as calling an 01/02 number. Choose a number from live stock at /0345-numbers.

They cost your callers and you exactly the same. 0345 is the range banks, utilities and large organisations use, so it looks established; 0330 is the most popular choice for growing businesses. Pick whichever suits your brand.

Yes. Ofcom created 0345 so organisations could leave 0845, which carries a service charge for callers. An 0345 number costs callers the same as a local call. Silux Call sells 0345 numbers for £4.99 a month; we do not sell 084 or 087 numbers.

Calls to 0345 cost the same as calling an 01 or 02 landline from any UK mobile or landline, and most call bundles include them, so for most callers they cost nothing extra. Only 0800/0808 numbers are free for every caller.

Yes. 0800 freephone numbers are £9.99 a month ex VAT with £100 of prepaid call credit. Incoming calls cost 3p a minute from UK landlines and 9p from UK mobiles or hidden numbers, charged per second; callers pay nothing. Calls from abroad are blocked unless you switch them on (195p a minute). Top up by card any time, or apply for a monthly-invoiced account. Choose a number at /0800-numbers.

Yes. 0330 UK-wide numbers are £4.99 a month ex VAT, no setup fee and no contract, added to any paid plan. Callers pay the same as calling an 01/02 number. Choose a number at /0330-numbers.

We email you when 90% and again when 95% of your credit is used. If it runs out, your 0800 number is paused (callers hear that it is temporarily unavailable) until you top up; your other numbers keep working. Top up any time by card, or, if you are a company, contact us for a monthly-invoiced account.

Choose 0330 for a national number that costs you nothing per call (callers pay a local rate). Choose 0800 when you want calls to be free for customers and are happy to pay per minute.

No. Because the business pays for every incoming 0800 call, 0800 numbers are £9.99 a month plus call credit, on a paid plan. The 7-day free trial includes one local number only.

BT Openreach is retiring the UK PSTN (and the WLR2 wholesale product) on 31 January 2027. Many exchanges are already on stop-sell, so new analogue lines cannot be ordered.

On 31 January 2027 any analogue line stops carrying calls. Phones, alarms, lifts and EPOS card terminals on that line stop working until they are migrated to an IP service such as VoIP.

Yes. UK number portability is a regulator-protected right. Silux Call ports UK landline (STAC) and mobile (PAC) numbers free on every paid plan (Entry and above). Porting is handled by our team and typically takes approximately 14 working days from submission; your old line keeps working until it completes.

For a 1–10 person UK business, expect from £4.75 a month on Entry to £18.95 a month (10 users, 1 landline) on Pro (Enterprise is quoted) with free UK porting on paid plans. Ancillary devices (lifts, alarms, EPOS) are £50–£400 per endpoint.

There is a 7-day Free Trial with no credit card: one user and one UK number allocated at random, with 30 outbound minutes. Paid plans do not carry their own trial; Plus instead starts at 99p a month for the first 2 months, one per customer. There is no free plan after the trial. Signing up takes about 60 seconds, with no sales call.

Silux Call starts with a 7-day Free Trial (1 user, 1 UK number allocated at random, 30 outbound minutes, no card), then Entry at £4.75 a month ex VAT with 2,000 outbound UK minutes, with no contract. Every plan includes a UK landline and its users.

Free Trial £0 for 7 days; Entry £4.75/month (1 user, 2,000 outbound UK minutes); Plus £8.95/month (3 users, unlimited UK calls, 99p a month for the first 2 months); Growth £11.95/month (6 users); Pro £18.95/month (10 users, includes 20 AI receptionist minutes); every plan includes 1 UK landline and extra landlines are £5.99/month; Enterprise priced on application. The AI receptionist is a £15/month add-on on other plans. Pay annually and save 10%. Prices are per plan with a UK landline included, in GBP, ex-VAT, no contract; Growth and Pro start at 2 users.

No. Every Silux Call plan is rolling and cancellable. The 7-day free trial needs no card.

Yes. Silux Call is a UK-domestic service billed only in GBP, so there is no FX or rounding risk, unlike USD- or EUR-anchored global providers.

An AI receptionist is software that answers your business phone in your brand voice, understands the caller, and resolves the request, books an appointment, or routes to a human — 24/7.

Silux Call’s AI receptionist is a £15/month add-on, and the Pro plan includes 20 AI receptionist minutes — typically far cheaper than a £2,000/month outsourced answering service.

Yes. AI minute packs add 50 minutes for £4.95, 100 for £8.95 or 250 for £19.95 (excl. VAT) to the current month, in one payment with no subscription. If the minutes run out, calls are answered the normal way until the month renews.

Silux Call screens every inbound call before your phone rings. On Growth and above (or as a £3.95/month add-on) the scam & spam shield checks each caller ID against rules — spoofed HMRC or government numbers, impossible or forged caller IDs and your own block list — and labels the call as a likely scam or blocks it, per your policy.

Yes. Recorded calls and voicemails are transcribed on the platform’s own speech engine with timestamps, full-text search and automatic card-number redaction, so you can read and search calls instead of re-listening.

Yes. From your dashboard you can book a 30-minute support callback in a UK time slot between 9am and 5pm, Monday to Friday, from the next working day, with priority emergency slots for urgent, service-affecting issues. See /support/book.

Yes. When a call is out of scope the AI hands off to a human agent in under 3 seconds, and a per-DDI toggle lets you keep sensitive lines fully human.

Silux Call supports UK GDPR-compliant call recording with a caller consent prompt, and publishes a Data Processing Agreement for customers. Silux Call does not offer HIPAA agreements and is not PCI DSS certified.

Yes, with a lawful basis (legitimate interest, contract, or consent) and a caller notification before recording starts, under UK GDPR and the Data Protection Act 2018. Silux Call ships a consent-prompt macro.

Yes. Ofcom requires VoIP providers to support 999/112. Silux Call routes emergency calls with your registered address and recommends battery/4G backup so it survives a power cut.

Yes when done properly. Silux Call encrypts signalling with TLS and media with SRTP on every call, supports SAML SSO and MFA, and offers KMS-backed recording encryption for regulated tenants.

No. Silux Call runs on iOS, Android, Windows, macOS, Linux and browser softphones, so existing computers and smartphones work immediately. IP desk phones are optional and auto-provisioned.

Silux Call does not currently offer Microsoft Teams Direct Routing. Teams users can run the Silux Call desktop or browser softphone alongside Teams for their UK business number.

HubSpot, Salesforce, Pipedrive and Zoho for click-to-dial and screen-pop, plus Xero, QuickBooks, Sage, Google Workspace, Microsoft 365, Zapier and Slack.

Incoming calls are always unlimited. Outgoing UK calls are unlimited within generous fair use: Plus 4,000, Growth 6,000 and Pro 10,000 minutes a month, shared by all your lines, plus 2,000 for each extra landline (£5.99). Top-ups start at £1.99 for 500 minutes. See /legal/fair-use.

Yes. The Silux Call API lets your own CRM or server start a call with one request: the named extension rings, and when it is answered we dial the number with your business caller ID. It also returns call history and call recordings as MP3. Included on Plus and above, or £2.50 a month on Entry. See /integrations/click-to-call-api.

Yes. GET /api/v1/calls returns your recent calls and GET /api/v1/recordings lists recordings with an MP3 download for each, using an API key from your dashboard. For a live feed as each call ends, add a webhook on the CRM Integration page.

A VoIP call needs connectivity, but Silux Call fails inbound calls over to 4G/mobile or an alternate site automatically during a broadband outage, so you stay reachable.

Yes. UK MSPs can rebrand the mobile and desktop softphone, bill end-customers via Stripe Connect, set per-tenant feature flags and earn 30–40% revenue share — including on Pro + AI.

Yes. The reseller portal provides multi-tenant provisioning, per-tenant SLA dashboards and affiliate attribution by signup link. Onboarding is typically three weeks.

The Overview page shows today's calls, minutes, numbers and voicemails at a glance, a setup checklist, recent calls and a 14-day call chart. The first page you see after signing in. It is a summary of your whole account — nothing on it changes how calls behave, so you cannot break anything here.

Figures only count calls made or received on this account. A brand-new account, or one whose number is still being ported, will show zero until calls start flowing.

The checklist is designed for first-time setup. Everything it links to is also in the left-hand menu, and the Help button on each page explains it in full.

It refreshes when you open or reload the page. For a second-by-second view of calls in progress, use Live Calls.

Every number on your account with its routing, call counts and minutes. See where each number sends its calls and switch Smart Answering on or off. Your list of phone numbers. Each number (also called a DID or DDI) can send its calls somewhere different — a person, a team, a menu, voicemail or the Smart Receptionist.

Every paid plan includes 1 UK landline. The Free Trial includes one number, allocated at random (you cannot choose it on a trial). Extra landlines are £5.99 a month each.

The number is moving from your old provider. It keeps working with them until the move completes, typically about 14 working days after a correct request.

Yes. Create a routing rule for each number pointing at the same hunt group, menu or mobile.

Numbers cannot be deleted from your dashboard, so a number on your vans, signs or website cannot be lost by accident. If you wish to give up a number, please contact support at info@siluxcall.co.uk. To stop calls ringing somewhere, change your Call Routing instead.

Usually because a payment failed. Open Subscription & usage, update your card, and the number is restored once payment succeeds.

Search live UK number stock by area code, town or memorable digits, buy it through secure checkout, then name it and choose where it rings. The shop for new phone numbers. Stock is live — what you see is available now — and covers UK geographic (01/02) landline numbers for every area code.

Numbers cannot be deleted from your dashboard, so a number on your vans, signs or website cannot be lost by accident. If you wish to give up a number, please contact support at info@siluxcall.co.uk. To stop calls ringing somewhere, change your Call Routing instead.

The monthly price and any setup fee are shown on each result before you buy. Every user on a paid plan already includes one number.

Usually within minutes of payment. It appears in your list and on Phone Numbers; point it somewhere in Call Routing and it is live.

No. Free Trial numbers are allocated at random, and you can't choose your number on a free trial. Paid plans choose their own number.

Yes. Any UK area code we have in stock can be used from anywhere.

Yes. Add SMS notifications and we text your mobile about missed calls, voicemails and more, so you never miss a customer.

Keep the number you already have. Fill in the porting request, sign the letter of authority online, attach a recent bill and track progress here. "Porting" means moving a phone number from your current provider to us so you keep the same number. Nothing changes for your callers — the same number simply starts ringing on Silux Call.

Typically about 14 working days from a correct submission. It depends on your current provider releasing the number, and any mismatch in the details can add time.

Porting is free on every paid plan (Entry and above). It is not available on the Free Trial.

No. It keeps working with your current provider until the switch, which usually happens with only a brief interruption.

Almost always because a detail did not match your provider's record — usually the installation address, postcode or account number. Check your latest bill and resubmit.

The form accepts geographic (01/02), mobile (07) and non-geographic (03/08) numbers. Contact support before porting a mobile number so we can confirm it can be supported.

Not until we confirm the port is complete. Cancelling first releases the number and the port fails.

Add a UK-wide 0330 or 0345 number, or an 0800 freephone number, to your account. 0330 and 0345 cost callers a local rate; 0800 is free for callers and paid from your 0800 call credit. An 0330 or 0345 number is a national number that is not tied to a town (0345 is the range banks and utilities use, and it replaced 0845). Callers pay the same as calling an 01 or 02 number. An 0800 number is a freephone number: it is free for callers from any UK mobile or landline, and your business pays for each incoming call from prepaid 0800 call credit.

£4.99 a month ex VAT, no setup fee and no contract. You pay nothing per incoming call.

The same as 0330: £4.99 a month ex VAT, no setup fee and no contract, and nothing per incoming call. Choose one at siluxcall.co.uk/0345-numbers.

None in cost, for you or your callers. 0345 is the range banks, utilities and councils use (it replaced 0845); 0330 is the most popular choice for growing businesses.

£9.99 a month ex VAT plus £100 of call credit to start. Calls cost 3p a minute from landlines and 9p from mobiles, charged by the second. Unanswered calls are free.

We email you when 90% and again when 95% of your credit is used. If it runs out, your 0800 number is paused (callers hear that it is temporarily unavailable) until you top up; your other numbers keep working. Top up any time by card, or, if you are a company, contact us for a monthly-invoiced account.

Not as standard, because those calls cost 195p a minute. Callers from abroad hear a short message that the number is UK-only, and you are not charged. You can allow them on the 0800 Credit page.

Yes. Calls to 0800 and 0808 numbers are free from all UK mobiles and landlines.

Yes. Like any number on your account, it can have its own greeting menu, opening hours or hunt group.

No. 0330, 0345 and 0800 numbers are added to a paid plan. The free trial includes one local number.

Create rules that send each number's calls to a mobile, a hunt group, a greeting menu, voicemail, the Smart Receptionist or any other number, with optional opening-hours timing. The rule book for incoming calls. For each phone number you choose a destination, and optionally make the rule depend on your opening hours and bank holidays.

Yes. Set your mobile to divert its calls to your Silux Call landline number, and you can answer them on your computer (Softphone) or on the Silux Call app for iPhone and Android. Set the divert on the mobile: on an iPhone go to Settings → Phone → Call Forwarding; on Android open the Phone app → Settings → Calls → Call forwarding. On most UK networks you can also dial **21* followed by your Silux Call number and # to divert every call, or **61* to divert only calls you do not answer, then press call. Dial ##21# to stop diverting. Your mobile network may charge for diverted calls, so check with them.

Forward to Mobile is for a UK mobile. Direct Number / External Line sends the call to any number or an external phone line — a landline, another office, or a call centre.

Forwarding a call to an outside number uses an outbound call from your allowance, the same as dialling it yourself.

Calls ring your extensions and then go to voicemail. Add a Voicemail fallback rule so the behaviour is always explicit.

Every plan, including the Free Trial. Forward to Mobile, Voicemail and Direct Number work on every plan. Time-Based Routing (opening hours and bank holidays) is included from Plus, or add Business-hours routing on its own for £2.00 a month.

Build the recorded menu that answers your calls: write what callers hear, pick a voice or upload a recording, and choose where each key press goes. A Greeting Menu is an IVR (Interactive Voice Response), sometimes called an auto-attendant or switchboard: "Thank you for calling. Press 1 for sales, 2 for support." Each key sends the caller somewhere.

Entry includes 1, Plus up to 3, Growth 8, Pro 20 and Enterprise 50. On the Free Trial a greeting menu can be added on its own, which includes 1 menu.

Yes. Upload MP3, WAV, M4A, OGG or FLAC, or record straight from your microphone. It replaces the spoken text.

Say what happens in your prompt and make sure there is an option for it — usually voicemail or a person.

Yes. IVR (Interactive Voice Response) is the industry name; we call it a Greeting Menu.

Every paid plan: Entry includes 1 menu, Plus 3, Growth 8 and Pro 20. Sub-menus from Plus.

Group people (or phones) under one destination. Ring them all at once, one by one, or taking turns, with a failover if nobody answers. A hunt group (or ring group) is a team that shares one incoming call. Instead of ringing one person, the call "hunts" through the group until someone picks up.

A hunt group rings people and, if nobody answers, fails over. A call queue holds callers in line with music and position announcements until someone is free. Use a queue when you regularly get more calls than people.

Yes — add the mobile number as a member.

Round Robin shares calls out in turn. Each new call starts with the next person in the group (call 1 → Amy first, call 2 → Ben first, call 3 → Cara first, then back to Amy). If that person does not answer, the rest of the group is tried one by one, then your failover. It suits sales or support teams where calls should be spread evenly.

Simultaneous rings everyone at once and is quickest to answer, best for small teams. Sequential always starts with the same first person, best when one person normally answers. Round Robin rotates who is rung first, best when calls should be shared fairly.

Creating a group does not change your calls on its own. Open Call Routing, press "Add Rule", pick your number, set Routing Type to "Hunt Group", choose the group and save. Calls to that number now ring the group.

The call goes to your Failover Destination: a mobile you typed, or voicemail. If you left it empty, the caller can leave a voicemail.

Entry and above. On the Free Trial they are not available.

Queue callers with hold music and position announcements, choose how calls reach your agents, and set what happens when the wait is too long. A call queue is a waiting line for phone calls. When everyone is busy, callers wait to music ("You are third in the queue") instead of hearing engaged or going to voicemail.

Yes — your default track from Hold Music, plus position announcements if you turn them on.

Plus and above. On Entry they can be added on their own from Features & add-ons.

Yes — open Live Calls for the real-time view of calls and agents.

Ring your desk, then your mobile, then any other number in sequence, with a ring time per step and a final action if nobody answers. Find me / follow me makes one incoming call chase you across your phones in turn, so a caller never has to try three numbers to reach you.

Similar idea, different purpose: find me / follow me chases one PERSON across their own phones; a hunt group rings several PEOPLE.

Plus and above. On Entry it can be added on its own.

Set opening times for each day, add bank holidays and closures, and choose what happens to calls when you are closed. Changes apply immediately. Your opening hours, as the phone system sees them. In hours, calls follow your normal routing; when closed, they are handled automatically.

Yes — saving updates the live phone system immediately.

Business Hours is your regular weekly pattern plus planned closures. Holiday mode (on the Do Not Disturb page) is one switch that overrides everything until you turn it off.

Plus and above. On Entry it can be added on its own as Business-hours routing.

Three switches that stop calls ringing: Do Not Disturb (right now), Enforce Working Hours (on a schedule) and Holiday / Out of Office mode (for a block of dates). Your availability controls. They change where calls go without touching your normal routing, so turning them off puts everything back exactly as it was.

No — it only affects incoming calls.

They hear your voicemail greeting, the same as if you had not answered.

Holiday mode is included from Entry. On the Free Trial it can be added on its own.

Yes. Do Not Disturb, Working Hours and Holiday mode switch the whole account, so every phone and every person follows, whoever pressed it. The Softphone page shows a notice on everyone's screen while DND or Holiday is on, and anyone can press the button again to turn it off. To stop just your own phone ringing, sign out of the softphone instead.

Keep one searchable directory of your staff with department, job title, extension, direct number, mobile and email. Your internal phone book. It powers dial-by-name: callers who know who they want can reach that person without going through reception.

Plus and above. On Entry it can be added on its own.

No. Users are logins to the dashboard. The directory is a phone book and can include people who never log in.

Play messages callers have left, read the transcript, download, archive or delete them, and see which greeting is on air. Your voicemail inbox for every mailbox on the account — a person, a department or a number.

Yes — Voicemail to Email is included on every plan.

Voicemail-to-text is included from Plus. Very short or silent messages may have no text.

Yes, using the mailbox PIN set on Voicemail Settings.

Create voicemail boxes, link each to an extension, set the PIN, message length and greeting, and choose email notifications. The settings for each voicemail box. A mailbox is where unanswered calls for an extension (or number) end up.

One for each user on your plan. The Free Trial includes one; Entry includes at least two.

Make sure you pressed "Use this" on the new greeting. The page then says a custom greeting is on air.

Switch off "Allow callers to leave a voicemail". The greeting still plays but no message is recorded.

Email every new voicemail to the address you choose, with your own subject line, the audio attached and an optional text transcription. Automatic emails for new voicemail, so you can hear messages on any device without logging in.

Every plan, including the Free Trial.

The page takes one address. Use a group or shared mailbox to reach several people; individual mailboxes can also have their own address on Voicemail Settings.

Press Send Test, check spam, and look at Recent Notifications — the Status column shows whether each email was sent.

Make professional announcements by typing them and choosing a natural voice, recording with your mic, or uploading audio — then put them on air. The greetings studio. Every message your system plays — voicemail greetings and menu prompts — is made and managed here.

No. Make and change as many as you like.

Plus and above. On Entry and the Free Trial it can be added on its own as the Voice greetings studio.

Phone calls carry a narrower range of sound than music speakers. Use "Hear it as a caller does" to check.

Choose a track from the licensed library or upload your own MP3 or WAV, and set the default that plays on hold and in queues. Music on hold (MOH) — the audio that plays when you put someone on hold or they wait in a queue. Silence makes callers think they have been cut off.

Every paid plan, from Entry. It is not part of the Free Trial.

Only with a licence for public performance. The System Library tracks are cleared for use.

Tracks loop; a short track keeps the file small and a message repeating at a sensible interval.

A working desk phone in a browser tab. Dial, answer, transfer, hold and transfer, add a third person, record, and use DND, hours and holiday shortcuts. A softphone is a phone that runs as software. This one runs in your browser (using WebRTC), signs in to your extension when the page opens, and rings in the tab. Nothing to install.

Not as standard. Every account calls UK landlines and mobiles only. If you dial abroad, a message lets you request international calling. Additional charges apply.

The tab lost its connection or your extension is not set up yet. Press Reconnect; if it says no extension is provisioned, contact support. A Network Quality test checks your connection.

Allow microphone access for the site in your browser, and check the right microphone is selected in your computer's sound settings.

Entry and above. On the Free Trial, transfer is an add-on.

On-demand recording is included on every paid plan, with full recording from Plus.

No. It runs in a modern browser.

Yes. In Chrome or Edge on your computer, open Softphone and press "Install desktop app" (or the install icon in the address bar). It opens in its own window with a desktop icon.

Press "More" on the call screen, then press the Silux Call icon. Unlock your phone if asked, and the app opens on your call with Transfer, Hold & Transfer, Record and the keypad. Apple decides how the iPhone call screen looks, so every calling app sits under "More" — the button cannot be renamed.

It protects the app's call settings. You choose it yourself: the first time you press Unlock in the app's Settings, the PIN you type (4 digits or more) becomes your PIN. After that, Unlock asks for it and keeps the settings open for an hour. Forgotten it? An account admin can reset it on Users (the key button), and you choose a new one the next time you press Unlock.

Incoming calls off or Do not disturb: your app does not ring and callers go to your voicemail. Outgoing calls off: the app cannot make calls out (999 always works). Voicemail off: callers who are not answered hear that nobody is available and no message is taken. Call forwarding: calls you do not answer are sent to the UK number you enter. Notifications: choose which alerts the app shows. Switches for features that are not on your plan are greyed out.

No. Only one phone per user can be logged in to the Silux Call app at a time. If you log in on a second phone, that phone takes over your calls and the first phone stops ringing. To move back, open the app on the other phone. If two people need the app, give each of them their own user on Users & Roles.

What every switch in the Silux Call app's Settings and Notifications does, why some are greyed out, how the PIN works and how Do not disturb works. The Silux Call app for iPhone and Android has two screens of switches. Settings controls how calls reach your phone (incoming, outgoing, voicemail, call forwarding, Do not disturb). Notifications controls which alerts the app shows. The switches are saved on our servers, so they work even when the app is closed, and they apply to you only, not to your colleagues.

Because that feature is not on your plan. For example, Call forwarding is greyed out on plans without call forwarding, and the Recordings alert is greyed out if call recording is not on your plan. Upgrade or add the feature in the dashboard and the switch becomes available.

No. It only stops your app ringing. If your number also rings colleagues, their phones still ring. If not, callers go to your voicemail, or to your forward number if you have Call forwarding on. To pass calls to a colleague, use a hunt group or call forwarding.

The app switch is for you only. Do Not Disturb on the dashboard is for the whole account: every call to your numbers goes to voicemail.

No. Alerts are just the messages on your phone. Calls still ring and voicemails, missed calls and recordings are still saved in the app and dashboard. The one exception is the Incoming calls alert: with it off, the app only rings while it is open on screen.

Ask an account admin to open Users in the dashboard and tap the key button (Reset app PIN). Then tap Unlock in the app and choose a new PIN.

No. Call forwarding goes to UK landlines and mobiles only.

Take your business calls hands-free on any Bluetooth headset, AirPods, earbuds or car kit, on the Silux Call app for iPhone and Android, the desktop app and the browser. Silux Call sends your business calls to whatever Bluetooth audio you are using: a work headset, AirPods or other earbuds, a speakerphone or your car. Your callers see your business number, not your mobile, and you talk hands-free.

Yes. Connect your AirPods to your iPhone or Android phone and your Silux Call business calls play through them. On iPhone you can also answer and end calls from the AirPods.

Yes. When your phone is connected to your car, business calls from the Silux Call app play through the car speakers and use the car's microphone, so you can talk hands-free.

Yes. Tap Audio on the call screen and choose Phone, Speaker or your Bluetooth device, at any point during the call.

Any Bluetooth headset, earbuds, speakerphone or car kit that works for normal phone calls on your phone or computer. That includes Apple AirPods, Beats, Samsung Galaxy Buds, Google Pixel Buds, Sony, Bose, JBL, Jabra, Poly (Plantronics), Sennheiser and EPOS, Logitech, Anker Soundcore, Shokz, Nothing, OnePlus, Huawei, Xiaomi, Skullcandy and Marshall.

Yes. Connect your Galaxy Buds to your phone and your Silux Call business calls play through them, on Samsung, other Android phones and iPhone.

Yes. Powerbeats Pro, Studio Buds, Solo and Studio Pro all work for business calls on iPhone and Android. On iPhone you can answer and end calls from them.

Yes, if the speaker has a built-in microphone (for example JBL Flip, Charge or Go models with hands-free calling). It then works as a speakerphone for your Silux Call business calls. Without a microphone, the sound plays through the speaker and you talk into your phone.

Yes. Huawei FreeBuds and FreeLace work with the Silux Call app on iPhone and on Android phones with Google Play. Newer Huawei phones without Google Play cannot install the app.

Yes. Panasonic and Technics Bluetooth headphones and earbuds with a microphone work for Silux Call business calls on your phone or computer.

iPhone, and Android phones with Google Play, including Samsung Galaxy, Google Pixel, Motorola, Xiaomi, OnePlus, Oppo, Honor, Sony Xperia, Nokia, Vivo and Realme (Android 7 or later).

Yes. Bluetooth gaming headsets from Razer, SteelSeries, HyperX, Corsair and Turtle Beach work like any Bluetooth headset with the app or your computer.

Yes. Bose QuietComfort, Bose 700, Sony WH-1000XM and Sony earbuds all work for Silux Call business calls on your phone or computer.

Yes. Jabra Evolve and Engage, Poly Voyager, Sennheiser and EPOS headsets work with the Silux Call app, the desktop app and the browser softphone. Pair them by Bluetooth, or use the USB dongle that comes with them on your computer.

Yes. When your phone is connected to the car, Silux Call business calls play through the car's speakers and microphone. On iPhone with CarPlay you can also answer from the car's screen and controls.

Yes. Speakerphones such as Jabra Speak, Poly Sync, Anker PowerConf and Yealink CP work with the app and the desktop app, so a small team can join a call round a desk.

No. They see your business number, whichever device you talk on.

Yes. Pair it with your computer and choose it as the computer's sound input and output, then use the softphone as normal.

No. Bluetooth works on every plan with the Silux Call app, desktop app or browser softphone.

See calls on hold in real time and resume them, set a maximum hold time, and call customers back automatically if they wait too long. Hold pauses a call without cutting it off. The caller hears your hold music until you come back.

Entry and above. On the Free Trial it is an add-on.

Your default track from Hold Music (every paid plan).

Hear a tone when a second call arrives while you are busy, choose how many calls can wait, and what happens when the limit is reached. Call waiting lets a second caller hold for you instead of going straight to voicemail or engaged.

Every plan, including the Free Trial.

Yes — each call uses one of your account's concurrent calls, which is Entry 1, Plus 2, Growth 3, Pro 5, plus one per extra landline. When none is free, the caller gets the "When Queue is Full" treatment.

Put a call into a numbered slot and pick it up from any phone by dialling the slot. Set the slot range, timeout and what happens if nobody collects it. Call park is like putting a caller in a numbered waiting room. Anyone on your system can collect them by dialling that number.

Transfer sends the call to one named person. Park leaves it in a slot so whoever is free picks it up.

Growth and above. On lower plans it can be added on its own.

Every Silux Call account, trial or paid, calls UK landlines and mobiles only. To call abroad, ask for international calling to be switched on. Extra charges apply. International calling means ringing a number outside the UK, for example +33 for France or 00 1 for the USA. It is switched off on every account as standard. This protects you from unexpected bills and from fraud, where someone gets into a phone system and runs up calls to expensive overseas numbers.

No. Free trials can call UK landlines, mobiles and freephone numbers only.

Not as standard. International calling is not included in any plan. Ask for it to be switched on; additional charges apply.

It depends on the country. We confirm the rates with you before international calling is switched on, so there are no surprises.

International calling is switched off on your account. You will hear a short message, or see one in the softphone. Send a request and we will be in touch.

Yes. Incoming calls from abroad to your UK number work as normal. The block only stops your outgoing calls.

Premium-rate and special numbers are blocked on every account to protect you from high charges and fraud.

Yes. 999 and 112 always connect, whatever your account settings.

Give each person or phone a 3 or 4 digit extension, assign it to a user, choose the device type, and call each other free anywhere in the world. An extension is a short internal number (e.g. 204). Calls between extensions stay inside your system, so they are free and work the same whether your colleague is next door or abroad.

Yes. They never touch the public phone network.

Growth and above. On lower plans they can be added on their own as Internal extensions.

Yes — set Device Type to Desk Phone and contact support for the phone's connection details. You can also get them yourself: save the extension as Desk Phone, open it again and Desk phone settings shows the SIP server (sip.siluxcall.co.uk, port 5060 UDP), the user name (the extension number) and a Get desk phone password button. Any standard SIP desk phone works, for example Yealink, Grandstream or Snom. A Desk Phone extension rings only the desk phone, so keep a separate Softphone extension for anyone who also uses the app or browser.

Live presence for every extension (free, ringing, on a call) and pickup groups that let team members answer each other's ringing phones. BLF (Busy Lamp Field) is the "light" that shows a colleague's line status. Pickup groups let you answer a colleague's ringing phone from your own.

It comes with internal extensions — Growth and above, or the Internal extensions add-on.

Yes. Dial *8 (most desk phones send this from their Pickup key) to answer a ringing phone in your pickup groups, or ** and the extension for one colleague.

Extensions appear once they are in a pickup group or have a softphone account. Add them to a group.

Create permanent dial-in conference rooms with participant and admin PINs, a participant limit, mute on join, join/leave tones and optional recording. A conference bridge is a "room" people dial into for a group call. No app, link or invite — just a number and a PIN.

Yes, by dialling in to the room with the participant PIN.

Growth and above. On lower plans it can be added as Conference rooms.

Create paging groups of extensions. Dial the group's extension to broadcast a live announcement, or use duplex mode for two-way intercom. Paging is a tannoy through your phones: you speak and it comes out of every handset in the group without anyone answering.

Growth and above. On lower plans it can be added as Paging & intercom.

It is designed for desk phones and softphones on your system.

Play a short private message to the person who answers before the caller is connected — e.g. "This is a business call" — the caller hears nothing. Call whisper is an announcement only the answering person hears. It is ideal when calls are forwarded to mobiles, so you know to answer "Good morning, Acme" not "Hello?".

No. Only the person answering hears it.

No — that is "whisper coaching" on Call Monitoring, where a supervisor speaks to a colleague during a live call.

Growth and above. On lower plans it can be added on its own.

Supervisor tools for live calls: listen silently, whisper coaching only your colleague hears, or barge in so both parties hear you. Monitoring lets a manager hear calls as they happen for training and quality. Staff must be told it is in place.

Yes for business purposes such as training and quality, provided staff are told and you follow data protection law. Take your own advice if unsure.

Growth and above. On lower plans it can be added on its own.

Your own phone, app or softphone rings first. Answer it and you are connected to the call in the mode you chose. Press another mode to switch, or Stop to leave. You need your own extension on the Users page to monitor.

Add team members with their own login and extension, give them a role, and add extra users (also called extensions) to any paid plan so more people can use the app at the same time. Users are the people who sign in to your account, each with their own extension. Each plan includes a set number of users (Entry 1, Plus 3, Growth 6, Pro 10) and 1 UK landline.

Open Users, find the person and click the key button (Reset app PIN), then confirm. They open the app, tap Unlock in Settings and type a new PIN of 4 digits or more, which becomes their PIN. Only account admins can reset PINs, and you can reset your own the same way.

No. Only one phone per user can be logged in to the Silux Call app at a time — logging in on another phone moves the calls to that phone and the first one stops ringing. Add a separate user for each person who needs the app.

Each user has their own extension. Your plan includes Entry 1, Plus 3, Growth 6 or Pro 10, and you can add extra users (extensions) to any paid plan. Teams of 25 or more are quoted as Enterprise.

Users and extensions are the same thing on Silux Call: one person with their own login and extension. On any paid plan, open Users & Roles and use "Add users (extensions)": choose how many, press Add and pay by card. Each extra one costs Entry £3.95, Plus £3.45, Growth £2.95 or Pro £2.45 a month plus VAT. If the next plan up is better value, the page tells you.

No. Users share your plan's calls at once. For more calls at the same time, add a landline (£5.99 a month).

No. Extra users (extensions) are for paid plans. Choose a plan first.

Yes. When your number is called, every user signed in rings at once as standard. To choose how they ring, open Hunt Groups and create a group with your users: Simultaneous (Ring All) rings everyone together, Sequential rings them one by one in your order, and Round Robin takes turns so the first ring moves round the team. Then point your number at the group in Call Routing. Hunt groups are included from Entry: Entry 1, Plus 3, Growth 8, Pro 20.

In Users & Roles, press Remove next to the purchase. Billing stops at the end of the month you have paid for.

Users share the plan's UK landline. Add more landlines for £5.99 a month each.

Yes. Every user included in your plan gets their own extension automatically, so each person signs in to the app as themselves and keeps their own call history. When your number is called, every signed-in user's phone rings at the same time and whoever answers first takes the call. To ring people one after another instead, set up a hunt group. How many calls can happen at once still depends on your plan.

A live call-centre view that updates every 5 seconds: active calls, today's inbound, outbound and missed, answer rate, longest wait and agent status. A wallboard — the screen call centres put on the wall to show what is happening on the phones right now.

It is part of advanced analytics — Plus and above, or the Advanced analytics add-on.

Use a real desk phone or cordless DECT phone on your Silux Call number. Any standard SIP phone works; here are the settings and a guide for each popular brand. A desk phone is a physical phone that plugs into your office internet with a network cable and signs in to your Silux Call account. It rings, transfers and holds calls just like the app, with proper buttons and a handset.

No. Any phone that supports standard SIP works. It must not be locked to another provider. Phones from BT Cloud Voice, Microsoft Teams-only phones and Cisco phones with Enterprise firmware usually are locked.

Yes, with an ATA (analogue telephone adapter) such as a Grandstream HT801/HT802 or Cisco SPA112. Set it up exactly like a desk phone: same server, extension number and password.

Desk phones use Extensions, which are included from Growth. On other plans add Internal extensions as an add-on.

Almost always a typing mistake in the server, user name or password. Unplug the phone at once so it stops trying (5 wrong tries in 10 minutes blocks your office for 48 hours), check each box against the Desk phone settings on the Extensions page, then plug it back in. If you have lost the password, press Get desk phone password for a new one and type that in.

Every desk phone in the building will show offline or "Registration failed" at the same time, while the app on mobile data still works. Unplug the phones, then contact support from the dashboard with your office's internet address (search "what is my IP" on a computer in the office). Support can lift the block once the password is fixed.

No. Each extension signs in on one device at a time, and a second phone on the same extension pushes the first one off. Give each desk phone its own extension, and put them in a hunt group if you want them to ring together.

A Desk Phone extension rings only that desk phone. If the same person also uses the app or the browser softphone, give them a separate Softphone extension and add both to a hunt group, or use Call Routing to ring both.

Every recorded call with date, caller, duration and size. Play it in the browser, read its transcript, download it as MP3 or the original WAV, or delete it. Your library of recorded calls. Recordings are held encrypted on UK infrastructure and kept for as long as your retention setting says.

Yes, for 30 days. Deleted recordings move to Recently deleted at the bottom of the Recordings page. Press Restore to bring one back. After 30 days they are removed for good, audio included.

Yes for business purposes, if you tell people and follow UK GDPR (have a reason, keep them secure, keep them no longer than needed). Take your own advice for regulated industries.

Encrypted at rest on UK infrastructure, kept for your retention period.

The file is still being saved after the call. It normally takes a few seconds.

Yes — Automatic call recording is included on Plus and above, or an add-on on lower plans (it needs Call recording too). Switch it on in Recording Settings.

Choose whether calls are never recorded, recorded after consent, or all recorded; set how long recordings are kept; and mute recordings while card numbers are given. The rules for call recording across your account, including the controls that keep card details out of recordings (PCI DSS).

On-demand records only when someone presses Record. Automatic records every call from start to finish without anyone remembering.

Plus and above (full call recording), or the Call recording add-on. Automatic recording of every call is included from Plus.

Consent-only plays your consent phrase to people who ring your number, then records (or waits for them to press 1 if you require it). On calls you make, press Record on the softphone once the other person agrees.

It keeps card numbers out of recordings, which is a key part of handling cards safely. Compliance also depends on how the rest of your business handles cards.

Automatically transcribe calls and voicemails, search every transcript, choose language and retention, and download transcripts as text files. Transcription converts recorded speech into written text on our own UK servers, so you can search "boiler warranty" and find the call in seconds.

Transcripts are timestamped text of the call. They do not label which speaker said each line.

Pro and Enterprise, or as an add-on on other plans. Plus includes voicemail-to-text only.

Transcription runs on our own UK servers.

Every call in and out with time, numbers, duration, status, cost and recording. Filter it, chart it, and export to CSV or Excel. Your call detail records (CDRs) — one line per call — plus totals and a daily chart.

Outbound calls beyond your allowance, or to numbers outside your plan, carry a charge. UK landline and mobile calls within your plan show no extra cost.

Basic call history is on every paid plan; this full analytics page is included from Plus, or as the Advanced analytics add-on.

An audit trail of every action on your account — sign-ins, settings changes, billing, users — searchable by date, category and text, with CSV export. A record of changes on your account. Use it when a setting is not what you expected.

The change was made automatically — for example by billing or a scheduled job — not by a person.

Email, SMS or WhatsApp alerts for missed calls, with the caller's number, time and a voicemail link, plus a list of your last 20 missed calls. Notifications that tell you about missed calls so you can call back before the customer rings a competitor.

Every plan includes them. WhatsApp alerts need WhatsApp on your account; dedicated SMS and WhatsApp call alerts are £1.50 add-ons on Call Alerts.

Missed Calls is about missed calls, mainly by email. Call Alerts are paid add-ons that text or WhatsApp you about any event you pick — every call, missed, diverted or a new voicemail — with a monthly allowance.

Run a self-serve VoIP readiness test that measures latency, jitter, packet loss and a call-quality score (MOS), and check our connection servers are reachable. A speed test built for phone calls. Calls need a steady connection more than a fast one, so it measures the things that cause choppy or robotic audio.

4.0 or above is excellent, 3.5–4.0 is fine, below 3.5 callers will notice problems.

Calls depend on jitter and packet loss, not download speed. This test measures those.

Text the people who call you automatically: when you miss their call, when they leave a voicemail, or when they press a key on your Call Menu for your link. UK mobiles only, no marketing. Automatic one-way texts from your business to someone who has just called you, paid for with text packs.

No. Caller Texts are service messages only, sent to someone who has just called you. Sales, offers and promotions are not allowed and are blocked.

No. Texts go to UK mobiles (07…) only. Overseas, landline and withheld callers are never texted.

No. Caller Texts are send-only: there is no text inbox and replies are not received, so do not ask callers to reply (for example "reply STOP"). Your business number still does not send or receive person-to-person texts.

Links to your own website (the domain of your business email) are used straight away. Any other link, for example a booking site, is checked by our team first to keep callers safe from fake links. Link shorteners such as bit.ly are not allowed.

It looked like marketing (offers, discounts, sales) or like a scam (asking for card or bank details, pretending to be a bank or HMRC). Repeated refused texts pause Caller Texts while we check the account.

Nothing more is sent until you buy another pack. Your calls are not affected.

One credit for up to 160 characters (70 if it includes emoji or special characters). Longer texts use more credits.

Buy SMS or WhatsApp call alerts, choose the mobile they go to and pick the events: every incoming call, missed calls, diverted calls and new voicemails. A text or WhatsApp message to your mobile when something happens on your business line, so you can call back before the customer tries someone else.

SMS call alerts and WhatsApp call alerts are £1.50 a month each, on any plan. Prices are shown on the button before you buy.

Alerts pause until the 1st of next month. Nothing else stops working.

SMS alerts go to UK mobiles only. WhatsApp alerts work with any mobile on WhatsApp.

Open Features & add-ons and press Remove on the alert add-on.

Receive business SMS notifications on your mobile the moment something happens: missed calls, voicemails and transcripts, callers who gave up waiting, suspicious calls, payments, number transfers and security alerts. You choose exactly which ones. Text notifications about your business line, sent to a UK mobile you choose, so you can call customers back quickly.

Enterprise includes them. On every other plan they are an add-on (£1.50 a month at the time of writing) in Features & add-ons.

Yes. Business SMS notifications go straight to your mobile, for up to 18 kinds of event that you choose.

Text notifications go to UK mobiles. For a mobile abroad, use WhatsApp notifications instead.

WhatsApp on your account: a shared WhatsApp Business inbox (Enterprise or £5/month add-on), WhatsApp missed-call notifications and WhatsApp call alerts. The WhatsApp menu takes you to your WhatsApp notification settings. WhatsApp is used three ways on Silux Call: the WhatsApp Business inbox, missed-call notifications, and the separate WhatsApp call alerts add-on.

The WhatsApp Business inbox is included on Enterprise and is an add-on on other plans. WhatsApp call alerts are a separate £1.50 add-on on every plan.

Book a support call and we will walk you through connecting your number.

The Chatbot Widget page explains the website chat bubble from our sister company Silux Chat and opens the Silux Chat app, where you build it. A chat bubble for your own website, provided by Silux Chat. It answers visitor questions, collects their details and lets a person take over. It is a separate product with its own account, managed in the Silux Chat app.

No. It is a separate product from our sister company Silux Chat, with its own account and pricing. Press Chat pricing on the Chatbot Widget page to see the prices.

No. It is one line of code pasted into your website. Most website builders have a box for custom code; if you are unsure, book a support call.

The SMS and WhatsApp add-ons explained (SMS call alerts, WhatsApp call alerts, SMS notifications and the WhatsApp Business inbox) with what each costs and exactly how to order it. Silux Call texts are notifications only: your business number does not send or receive texts. Silux Call texts are notifications to your own mobile about calls and voicemails; your business number does not send or receive texts. WhatsApp can also be used for notifications, or as a shared inbox for customers who WhatsApp you. Each is a separate add-on, so you only pay for the one you need.

At the time of writing: SMS call alerts £1.50/month, WhatsApp call alerts £1.50/month, SMS notifications £1.50/month and the WhatsApp Business inbox £5/month, all excluding VAT. The live price is always shown in your dashboard before you pay.

SMS notifications and the WhatsApp Business inbox are included on Enterprise. Call alerts are add-ons on every plan.

Yes. Business SMS notifications go straight to your mobile: missed calls, voicemails, callers who gave up waiting, suspicious calls, payments and more. You choose which.

As soon as payment goes through.

SMS goes to UK mobiles. WhatsApp works with any mobile number on WhatsApp.

Alerts pause until the 1st of next month; calls and voicemails still arrive as normal.

See your plan's Smart Voice features, which are active, and request ones that need setting up. Pro includes 20 Smart Voice minutes a month; Enterprise 300. Smart Voice is our voice product — natural voices that answer calls, take messages and book appointments. It runs on our own UK servers.

Pro (20 minutes a month) and Enterprise (300 minutes a month). On other plans the Smart Receptionist is an add-on.

It needs something connected before it can go live — for example a carrier or an external service. Our team will contact you.

Switch Smart Voice on, write the instructions it follows, set reply length and style, cap sessions per day, add an optional webhook, and test the connection. The settings behind smart answering. Nothing needs installing — it runs on Silux Call's own UK platform.

No. Smart Voice runs on our own UK platform.

Pro and Enterprise, or the Smart Receptionist add-on.

The Smart Receptionist answers in your chosen voice, finds out what the caller needs, answers routine questions, books appointments and passes real opportunities to you. An automated receptionist provided by our sister company Silux Voice. The page opens its control panel inside your dashboard.

Pro (20 minutes a month included) and Enterprise (300). On other plans it is an add-on at £15 a month.

Yes — tell it when and to whom to hand over in your instructions.

Calls are answered the normal way (menus, ringing, voicemail) until the month renews. You can buy an AI minute pack at any time from Minutes & top-ups: 50, 100 or 250 extra AI minutes, added straight away.

Buy 50, 100 or 250 extra AI receptionist minutes in one payment. They are added to this month straight away, so the AI keeps answering through a busy spell. A one-off top-up for the Smart Receptionist. Your plan includes a monthly AI allowance (20 minutes on Pro, 300 on Enterprise); a pack adds to it for the current calendar month.

50 minutes for £4.95, 100 for £8.95 or 250 for £19.95, excl. VAT. One payment, no subscription.

No. Pack minutes are added to the current calendar month and end with it, like your plan minutes.

Any account with the Smart Receptionist: Pro, Enterprise, or any plan with the Smart Receptionist add-on.

Nothing breaks. When the AI minutes are used, calls are answered the normal way (menus, ringing, voicemail) until the month renews.

Every inbound call is screened before your phone rings. Choose what happens to suspected scams, add your own block and allow rules, and test any number. Rule-based screening for fake and nuisance calls — for example a scammer showing a real HMRC or bank number that only ever receives calls.

Forged and impossible numbers cannot be real customers. For everything else you choose the action; Label and Press 1 never stop a real person getting through.

Growth and above. On lower plans it can be added on its own. A basic blocked-numbers list is included from Entry.

Register the installation address for your numbers so 999/112 operators know where to send help, and read the VoIP emergency-calling limitations. On VoIP, emergency operators are given the address you register — not your live location. This page is where you keep that address correct.

Yes, but over VoIP it depends on your power and internet working, and the operator is given your registered address. Keep a mobile for emergencies.

Register the address you usually call from and tell the operator your location if you call from elsewhere.

Callers type their card number on their own keypad, your staff never hear it, recordings pause automatically. See every payment, filter by status and refund. Secure phone payments (also called IVR or DTMF payments). Card details go straight to the payment provider, keeping them out of your business and your recordings.

Pro and Enterprise, or as an add-on on other plans.

It is built for PCI DSS: card numbers are entered by keypad, masked, and kept out of recordings. Your wider compliance depends on your own processes.

Connect Salesforce, HubSpot, Zoho, Pipedrive or any webhook-compatible system to log ended calls, missed calls and voicemails automatically. A link between your phone system and your customer records (CRM), so calls are logged against the right contact without anyone typing.

Growth and above. On lower plans it can be added on its own.

Yes, and it is free on every plan: see "Clio: log every call in Clio". Press Connect to Clio on this page.

Choose Custom Webhook and enter the address your system gives you.

Yes, with the Silux Call API (dashboard → API). Your CRM sends the number and the extension to ring; the extension rings, and when it is answered we dial the number. See the API guide.

Connect Clio Manage once and every call, missed call and voicemail is logged in Clio on the caller's contact and open matter. Free on every plan, including the free trial. A link between Silux Call and Clio Manage, the legal practice software, so phone calls are recorded in the client file without anyone typing a phone note.

No. Clio call logging is free on every Silux Call plan, including the 7-day free trial.

Under Communications, on the caller's contact and, when they have exactly one open matter, on that matter.

The number was not on a Clio contact. Add it to the contact and future calls link automatically.

LEAP call logging is in development. Until then you can send every call to any system with webhooks and the API.

The add-on store. Every feature shows whether your plan includes it, whether you already pay for it, or its monthly price. Add to basket, check out, and it switches on immediately. The shop for individual features. Instead of upgrading your whole plan, you can add just the one thing you need — it works on any plan.

Yes. An add-on switches the feature on whatever plan you are on, and you keep it if you change plan.

At checkout, then monthly with your subscription. Prices are shown excluding VAT; 20% VAT is added at checkout.

No. If your plan includes it, or you already pay for it, the store will not let you buy it.

Every price is on this page. The public Help Centre lists them per plan too.

See your current plan and usage, upgrade, manage cards and Direct Debit, and download PDF invoices and statements. Where you manage how you pay.

Prices are shown excluding VAT. UK VAT at 20% is added at checkout and shown on your invoice.

Yes, by BACS Direct Debit. It needs an extra verification step — set it up through the billing portal or ask support.

Your plan rate multiplied by your number of users, plus any add-ons and usage beyond your allowance.

How outgoing minutes are counted across all your lines, the fair-use minutes on each plan, calls at once, and how to top up or add a line in seconds. Every plan includes outgoing UK minutes each month. Plus, Growth and Pro say "unlimited UK calls": that is unlimited within generous fair-use minutes. Incoming calls are always free and unlimited.

No. Incoming calls are never counted and never limited.

Yes. Every outgoing call on the account counts towards one monthly total, whichever line, user or device makes it.

Outgoing calls pause until you top up, add a line or upgrade. Incoming calls and 999 keep working.

For accounts opened from 5 November 2026, straight away. For accounts opened before then, from 7 December 2026.

No. Minutes and top-ups last until the end of your billing month.

Your plan, monthly total, billing status, next charge, minutes used this period, trial end date, and cancel or reactivate your subscription. The plain-English summary of your subscription and what happens next.

The line is disconnected and the number returns to our pool. Order a plan before then to keep service.

We retry and tell you when. If it fails again the line is disconnected, so update your card as soon as you see the warning.

Port it to your new provider before your paid period ends.

See your international calling bundles: included destinations, included minutes, minutes used, overage minutes and overage charge. A bundle is a pool of minutes to specific countries for a fixed monthly price, cheaper than paying per minute.

No — UK calls are covered by your plan. Bundles are for international calls.

Yes. Every account calls UK numbers only as standard. Ask for international calling to be switched on (additional charges apply), and we can add a bundle at the same time.

Your organisation details, Beginner or Advanced mode, the features and limits on your account, webhooks, two-factor authentication and password. Account-wide settings and security.

You may be in Beginner mode — switch to Advanced in Interface Mode.

Entry 1, Plus 2, Growth 3, Pro 5 — plus one more for each extra landline. It is shown as Max Concurrent Calls.

Where the banner says so, yes.

When to upgrade versus buying one add-on, how plan pricing works, how to add extra landlines, and what changes the moment you upgrade. Every Silux Call plan includes 1 UK landline and a set number of users (Entry 1, Plus 3, Growth 6, Pro 10). Each plan unlocks more of the phone system; extra landlines are £5.99 a month and add-ons let you pick single features without upgrading.

No. Add-ons you pay for separately are kept on any plan.

Pro rata: your old plan for the days you used it and your new plan for the days left in the billing month. You are never charged for two plans at once, and from the next month you pay the new plan price.

No. Every self-serve plan starts at 1 landline and its included users, and you can add landlines as you grow. Enterprise is for teams of 25 or more.

Each plan includes 1 UK landline that its users share. Add more landlines for £5.99 a month each.

Start calls with one click from your own CRM, booking system or spreadsheet, and pull your call history and call recordings into it, using a secure API key. An API (a way for software to talk to Silux Call) for your own systems. Your system asks us to start a call, or asks for your call history and recordings, and we do the rest. You do not need to be a developer to use it with a ready-made tool, but someone will need to paste a few lines into your system once.

It is part of the package on Plus, Growth, Pro and Enterprise at no extra cost. On Entry, add API access for £2.50 a month from Features & add-ons. The Free Trial does not include it. There is no per-call API fee.

Account admins. Other users can open the API page but cannot create or revoke keys.

Yes. The extension you name rings on whatever it is signed in to: the mobile app, the browser softphone or the desktop app, with any headset used there.

The same as your phones: UK landlines, UK mobiles and freephone numbers.

Yes. The OpenAPI file is at https://www.siluxcall.co.uk/api/openapi.json. Most developer tools, and AI coding assistants, can read it directly.

A step-by-step test of the Silux Call API from a terminal: list your extensions, then ring your own extension and dial a number. A quick check that your key works before you connect your own system. You only need a computer with a terminal (Command Prompt, PowerShell, Terminal on a Mac, or any Linux shell). curl is built into Windows 10 and later, macOS and Linux.

It must be signed in somewhere: the mobile app, browser softphone or desktop app. If the reply said "ringing_extension" but nothing rang, open the app and try again.

No. Calls cost the same as calls from your phone, and the API itself has no per-call fee.

It is part of the package on Plus, Growth, Pro and Enterprise at no extra cost. On Entry, add API access for £2.50 a month from Features & add-ons. The Free Trial does not include it. There is no per-call API fee.

How Silux Call API keys work, where to keep them safe, how to change a key without downtime, and what to do if one is exposed. An API key is a long secret, starting sk_live_, that proves a request comes from your account. Anyone who has it can start calls and read your call history and recordings, so treat it like a password.

No. We only keep a scrambled copy, so nobody can read it back. Revoke the lost key and create a new one.

No. Anyone could copy it from the page. Your page should ask your own server, and your server calls the API with the key. See "Add a Call button to your own CRM".

No. A key works until you revoke it.

Only account admins see the key list, and even they only see the first characters after creation.

Everything about starting a call through the API: what to send, what comes back, what the caller and the customer see, and what can go wrong. One request that starts a call between one of your extensions and any UK number. Your extension rings first; when it is answered, we dial the number. To the person you are calling it looks exactly like a call from your business number.

Your business number, exactly as if you had dialled from your phone.

After 30 seconds the attempt ends and nothing is dialled. Nothing is charged.

No. Like your phones, the API calls UK landlines, mobiles and freephone numbers only. A non-UK number gets the error "international_not_enabled".

Up to 20 a minute per key. How many calls can be live at once follows your plan.

It follows your normal recording settings, exactly like a call from your phone.

Copy-ready recipes for putting a "Call" button next to every phone number in your own CRM, spreadsheet or booking system, safely. The safe pattern is always the same: the button in your page asks YOUR server to make the call, and your server calls Silux Call with the API key. The key never reaches the browser.

A tel: link opens whatever phone app the computer chooses. The API is better for a CRM: it always rings the right Silux Call extension and uses your business number.

Their own workflow or custom-code tools can send the same request from their servers. For call logging into them, use the CRM Integration page.

It is part of the package on Plus, Growth, Pro and Enterprise at no extra cost. On Entry, add API access for £2.50 a month from Features & add-ons. The Free Trial does not include it. There is no per-call API fee.

Pull your recent calls into your own system: what each field means, how to fetch only new calls, and how to match calls to your contacts. A list of the calls on your account, newest first, the same calls you see in Call Records in the dashboard.

No. Your bill and minutes are on the Billing and Minutes pages in the dashboard.

As far back as your Call Records page in the dashboard; use "before" to page back.

It is part of the package on Plus, Growth, Pro and Enterprise at no extra cost. On Entry, add API access for £2.50 a month from Features & add-ons. The Free Trial does not include it. There is no per-call API fee.

Get a message on your own server the moment a call starts, is answered, is missed or ends, when a voicemail arrives and when a recording is ready. Every event, its fields and how to check it came from us. A webhook is an address on your server. When something happens on a call we send it a short JSON message (an HTTP POST), so your CRM or dashboard updates by itself, with no polling.

No. Webhooks work on their own. You need a key only to download recordings or start calls from your system.

Yes. Add a webhook for each address.

Nobody picked up. Outgoing calls that are not answered send call.started and call.ended; incoming ones also send call.missed.

Copy your call recordings into your CRM or your own storage: list them, then download each one as an MP3. The same recordings you can play in the dashboard, available to your own system. Which calls are recorded depends on your plan and your recording settings; the API does not change that.

Either no calls have been recorded yet, or recording is not switched on. Check your plan and Recording Settings in the dashboard.

No. Delete them in the dashboard. The API only reads them.

The link only works with your API key, so it cannot be opened by someone else. Download the MP3 and share the file securely instead.

It is part of the package on Plus, Growth, Pro and Enterprise at no extra cost. On Entry, add API access for £2.50 a month from Features & add-ons. The Free Trial does not include it. There is no per-call API fee.

Every error the Silux Call API can return, what it means and how to fix it, plus the request limits. When something goes wrong, the API answers with an HTTP status and a JSON body like {"code":"invalid_api_key","message":"…"}. The code is for your software; the message is plain English you can show to a person.

Contact our support team with what you are building and we will look at it.

Every click-to-call made through the API is listed on your account's activity log, with the key name and extension.
