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 trial is TIME-LIMITED to 14 days and capped at 1 user, one randomly allocated number and 30 outbound minutes. At the end the line is disconnected unless you order a plan. One trial per person/household.

14-day free trial: 1 user, one UK landline allocated at random, 30 minutes, no card; Plus at 99p per line for the first 3 months (one line per customer); 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 trial 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.
