Frequently asked questions

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 every paid plan (Entry and above). Porting is handled by our team and typically takes approximately 14 working days from submission; your old line keeps working until it completes.

For a 1–10 person UK business, expect £4.75–£14.95 per user/month (Enterprise is quoted) with free UK porting on paid plans. Ancillary devices (lifts, alarms, EPOS) are £50–£400 per endpoint.

There is a 14-day Free Trial with no credit card: one user and one UK number allocated at random, with 30 outbound minutes. Paid plans do not carry their own trial; Plus instead starts at 99p for your first user for the first 2 months, one per customer. There is no free plan after the trial. Signing up takes about 60 seconds, with no sales call.

Silux Call starts with a 14-day Free Trial (1 user, 1 UK number allocated at random, 30 outbound minutes, no card), then Entry at £4.75 per user/month ex VAT with 2,000 outbound UK minutes, with no contract. Prices are per user, and every user gets their own UK number.

Free Trial £0 for 14 days; Entry £4.75/user/month (2,000 outbound UK minutes); Plus £8.95/user/month (unlimited UK calls, 99p for your first user for the first 2 months); Growth £9.95/user/month; Pro £14.95/user/month (includes 20 AI receptionist minutes); Enterprise priced on application. The AI receptionist is a £15/month add-on on other plans. Pay annually and get 2 months free. Prices are per user (every user gets their own UK number), in GBP, ex-VAT, no contract; Growth and Pro start at 2 users.

No. Every Silux Call plan is rolling and cancellable. The 14-day free trial needs no card.

Yes. Silux Call is a UK-domestic service billed only in GBP, so there is no FX or rounding risk, unlike USD- or EUR-anchored global providers.

An AI receptionist is software that answers your business phone in your brand voice, understands the caller, and resolves the request, books an appointment, or routes to a human — 24/7.

Silux Call’s AI receptionist is a £15/month add-on, and the Pro plan includes 20 AI receptionist minutes — typically far cheaper than a £2,000/month outsourced answering service.

Silux Call screens every inbound call before your phone rings. On Growth and above (or as a £3.95/month add-on) the scam & spam shield checks each caller ID against rules — spoofed HMRC or government numbers, impossible or forged caller IDs and your own block list — and labels the call as a likely scam or blocks it, per your policy.

Yes. Recorded calls and voicemails are transcribed on the platform’s own speech engine with timestamps, full-text search and automatic card-number redaction, so you can read and search calls instead of re-listening.

Yes. From your dashboard you can book a 30-minute support callback in a UK time slot between 9am and 5pm, Monday to Friday, and grab a same-day emergency slot for urgent, service-affecting issues. See /support/book.

Yes. When a call is out of scope the AI hands off to a human agent in under 3 seconds, and a per-DDI toggle lets you keep sensitive lines fully human.

Silux Call supports UK GDPR-compliant call recording with a caller consent prompt, and publishes a Data Processing Agreement for customers. Silux Call does not offer HIPAA agreements and is not PCI DSS certified.

Yes, with a lawful basis (legitimate interest, contract, or consent) and a caller notification before recording starts, under UK GDPR and the Data Protection Act 2018. Silux Call ships a consent-prompt macro.

Yes. Ofcom requires VoIP providers to support 999/112. Silux Call routes emergency calls with your registered address and recommends battery/4G backup so it survives a power cut.

Yes when done properly. Silux Call encrypts signalling with TLS and media with SRTP on every call, supports SAML SSO and MFA, and offers KMS-backed recording encryption for regulated tenants.

No. Silux Call runs on iOS, Android, Windows, macOS, Linux and browser softphones, so existing computers and smartphones work immediately. IP desk phones are optional and auto-provisioned.

Silux Call does not currently offer Microsoft Teams Direct Routing. Teams users can run the Silux Call desktop or browser softphone alongside Teams for their UK business number.

HubSpot, Salesforce, Pipedrive and Zoho for click-to-dial and screen-pop, plus Xero, QuickBooks, Sage, Google Workspace, Microsoft 365, Zapier and Slack.

A VoIP call needs connectivity, but Silux Call fails inbound calls over to 4G/mobile or an alternate site automatically during a broadband outage, so you stay reachable.

Yes. UK MSPs can rebrand the mobile and desktop softphone, bill end-customers via Stripe Connect, set per-tenant feature flags and earn 30–40% revenue share — including on Pro + AI.

Yes. The reseller portal provides multi-tenant provisioning, per-tenant SLA dashboards and affiliate attribution by signup link. Onboarding is typically three weeks.
