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.

GDPR call recording UK 2026: the rules in plain English

You need a lawful basis

Under UK GDPR Art. 6 you need one of: contract, legitimate interest, legal obligation, or consent. For most B2B "quality and training" recording, legitimate interest is the right answer.

You must notify the caller

A one-sentence pre-call announcement is sufficient. The default Silux Call prompt: "This call may be recorded for training and quality purposes. If you would prefer not to be recorded, please let us know."

Two-party consent regions

Some US states (California, Florida, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania, Washington) require positive consent from both parties. If your business takes calls from those regions, switch to require explicit DTMF consent on the Recording Settings page.

Retention

UK GDPR says "no longer than necessary". The sweet spot for most B2B is 90 days. HIPAA tenants get locked to 2,190 days (6 years). Insurance and FCA tenants typically pick 6 years too.

What you can never do

Record without notification (criminal under RIPA in some scenarios).
Sell call recordings to third parties.
Use recordings to train AI without explicit consent for that purpose.
Refuse a data-subject access request for a recorded conversation.

One-click compliance

Dashboard → Compliance Reports → Generate produces an auditor-ready PDF in 5 seconds: 12 months of consent events, recording inventory, retention proof, and a SHA-256 of the document for tamper-evidence.
