When does the UK PSTN switch off?

BT Openreach is retiring the UK PSTN (WLR 2) on 31 January 2027. Every UK business landline must move to a digital service such as VoIP or full-fibre voice before that date.

What is the cheapest UK business VoIP?

Silux Call offers a free seat tier (1 user, 1 UK DDI, 30 minutes/month) and Pay-as-you-go from £0/month + £0.02 per UK landline minute, with no contract. Paid plans start at £6.95/user/month and come with a 30-day free trial.

Does Silux Call have a free trial, and do I need a credit card?

Yes. Every paid plan comes with a 30-day free trial and no credit card is required to start — most UK rivals offer only a 7 or 14-day trial, and several require a card up front. You can also stay on a permanently free seat with no card at all. Signing up takes about 60 seconds.

How quickly can I get a UK virtual landline number?

You can sign up in about 60 seconds and choose a UK virtual landline number (020, 0161, 03 or 0800) instantly — no engineer visit, no hardware and no contract. Existing numbers port across free on Plus and above, typically within 24 hours.

Can I keep my existing phone number?

Yes — Silux Call offers free UK number porting on Plus and above, typically completing in 24 hours. We support PAC and STAC porting workflows.

Does Silux Call work with Microsoft Teams?

Yes — Silux Call supports Microsoft Teams Direct Routing on the Pro tier, including a self-service onboarding wizard that issues the PowerShell snippet for your Teams admin.

Is Silux Call GDPR and HIPAA compliant?

Silux Call ships UK GDPR-compliant call recording with two-party consent flows, plus one-click HIPAA enrolment that locks 6-year retention, KMS-backed encryption, and PCI DTMF redaction. A one-click compliance report exports an auditor-ready PDF.

How does Silux Call block scam calls?

Silux Call screens every inbound call with an AI scam shield in under 0.5 seconds. Known HMRC, parcel, and account-spoof patterns are blocked before your phone rings — a feature no other UK business VoIP provider ships.

How to get a free virtual phone number in the UK (2026)

You can get a real UK phone number for £0/month with no card on the Silux Call free seat. It is a proper virtual number — geographic (020, 0161, 0121…) or 03 — that rings on an app, desk phone or mobile, with no copper line and no line rental.

What "free" actually includes

One UK number on the permanently free seat (not a 30-day teaser).
Free voicemail-to-email with transcripts.
Free call forwarding/divert to your mobile.
30 outbound UK minutes a month; inbound is unlimited.

Where the limits are (honestly)

The free seat is one user with 30 outbound minutes. Need more? Run a 30-day free trial of a paid plan, or move to Pay-as-you-go at £0.02/min. Extra numbers are £1/month and 0800 numbers sit on a paid plan because freephone carries an inbound cost to you.

How to set it up

Register for the free seat — no card.
Pick a local area code (e.g. an
020 London number
or
0161 Manchester number
).
Install the app on your phone or open the browser softphone.
Set voicemail and call-divert rules. Done.

Because it is VoIP, your free virtual number already survives the 2027 PSTN switch-off — unlike the copper line it replaces.
