Free VoIP trial for UK businesses

Silux Call’s free VoIP trial lets a UK business test the full hosted phone system — UK number, app, IVR, voicemail and AI features — at £0, with no card required, no contract and no obligation to continue. At 30 days it is one of the longest no-card trials in UK business VoIP (most rivals offer 7–14 days or none), and signup takes about 60 seconds. The free seat is permanent (not time-limited) but capped at 1 user, 1 number and 30 outbound minutes a month. The 30-day paid-plan trial unlocks every feature; you only add a card if you keep it.

Permanently free seat: 1 user, 1 UK DDI, 30 mins/month, no card; 30-day free trial of any paid plan (Lite, Plus or Pro); Mobile, desktop and browser softphone; Voicemail-to-email and call forwarding included; Free PSTN switch-off audit with every account.

No. You can start the Silux Call free seat and free trials without a card. You only add payment details if you choose to upgrade to a paid plan.

Yes. Silux Call runs entirely over IP, so it is unaffected by the 31 January 2027 PSTN switch-off — and every account includes a free WLR2 migration audit.
