Illustrative scenarios showing how teams use Silux Call.
We were dreading the 2027 switch-off. Silux Call ported our 0207 numbers in under 24 hours and the smart receptionist now picks up out-of-hours bookings we used to lose. Saved us hiring a second receptionist.
Practice Manager · Camden Dental Practice
We take client-account top-ups over the phone. DTMF redaction kept us in SAQ-A scope and saved roughly £20k a year in audit costs vs our previous setup. Setup took an afternoon.
Founder · Whitford Legal LLP
Our consultants went from 30 calls/day to 70. The intelligent post-call summary writes itself into Bullhorn — none of the typing we used to lose 90 minutes a day to.
Operations Director · Mercer Recruitment
We rebranded the Flutter softphone in 15 minutes through the dashboard. Stripe Connect handles our customer billing. Margin is exactly what they said it would be.

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 Plus and above, typically within 24 hours, with no loss of calls.
For a 1–10 user UK SMB, expect £6.95–£17.95 per user/month plus £0–£30 one-off porting. Ancillary devices (lifts, alarms, EPOS) are £50–£400 per endpoint.
Yes. Every Silux Call paid plan comes with a 30-day free trial and no credit card is required — one of the longest no-card trials in UK business VoIP, where 7 or 14-day (often card-required) trials are the norm and several providers offer no trial at all. You can also stay on a permanently free seat for as long as you like. Signing up takes about 60 seconds, with no sales call.
Silux Call has a permanently free seat (1 user, 1 UK DDI, 30 minutes/month) and Pay-as-you-go from £0/month plus £0.02 per UK landline minute, with no contract — among the cheapest entry points in UK business VoIP.
Move your UK numbers to Silux Call. 30-day free trial, no card, 60-second signup, GBP pricing and free 24-hour porting.
