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.

FAQs — Sheffield

Can I keep my Sheffield phone number?

Yes. We port South Yorkshire landline and mobile numbers free on Plus and above, typically within 24 hours via the PAC/STAC process. Existing 0114 numbers move across without losing a call.

When does the PSTN switch off for Sheffield?

BT Openreach is retiring the UK PSTN (WLR2) nationally on 31 January 2027. Many Openreach exchanges serving Sheffield are already on stop-sell, so analogue lines can no longer be ordered there — migrating early avoids a rushed cut-over.

Is Silux Call regulated in the UK?

Silux Call is operated by Silux Telecom Ltd, registered in England & Wales, and UK business telephony is regulated by Ofcom. That framework is what sets your right to keep your number when you switch (via the PAC/STAC process), the rules on emergency 999/112 access from a VoIP line, and the complaints route we publish in our Complaints Code of Practice. Silux Call follows Ofcom's General Conditions of Entitlement for Sheffield customers as for every other UK location.

Can I call 999 from a VoIP phone in Sheffield?

Yes. Emergency calls to 999 and 112 work from Silux Call, and we hold the Sheffield service address you register so emergency operators receive a location. Because a VoIP line depends on power and broadband, Ofcom expects providers to be clear about that: keep a charged mobile as a backup for a power cut, exactly as you would with any internet-based phone service.

What does business VoIP cost in Sheffield?

Silux Call has a permanently free seat, Pay-as-you-go at £0.02/min UK landline, and paid plans from £6.95/user/month, all billed in GBP with no contract. There is no premium for Sheffield or any other UK location.

Do I need new phones for my Sheffield office?

No. Silux Call runs on the mobile, desktop and web softphone, so existing computers and smartphones work immediately. IP desk phones are optional and provisioned automatically if you want them.

Can Sheffield businesses get a local 0114 number?

Yes. New 0114 area-code DDIs are provisioned in seconds, or you can port your existing Sheffield number for free on Plus and above.

Can I get a free phone number in Sheffield?

Yes. Silux Call's permanently free seat includes one free UK number — a local 0114 Sheffield number or an 03 number — with free voicemail-to-email and call divert, no card required. You get 30 outbound minutes a month free; add more numbers from £1/month.
