What the switch-off actually means for your business
The PSTN is the analogue network that has carried UK phone calls for decades. Openreach is retiring it and moving every voice service onto IP — a straightforward change for a simple phone line, and a project for a site with alarms, card machines and lifts wired into it.
Most businesses we review are still running at least one line nobody has accounted for. Those are the lines that fail silently after the switch-off, so a free line review is the first step, not a new phone system.
Lines and devices that must move
If any of these are on your site, they need a migration plan before 31 January 2027.
- Business phone lines, ISDN2 and ISDN30 circuits
- Alarm and intruder signalling lines
- Card payment terminals (PDQ) and older EPOS kit
- Lift, gate, door-entry and emergency phones
- Fax machines and dial-up monitoring equipment
- Out-of-hours and separate voice-only lines
How we get you off analogue
1. Free line review
We audit every analogue line and device on your site and map what genuinely needs to move — and what can be retired with no replacement.
2. Voice to the cloud
We port your geographic and 03 numbers onto Cloud Voice with auto-attendant, hunt groups and call recording, usually within 7–10 working days.
3. Devices that can't move to VoIP
Alarms, PDQs, lifts and telemetry get a 4G/5G data SIM instead — a dedicated connection on a 30-day rolling contract, delivered next day.
4. Broadband that stays up
Pair voice with full-fibre broadband and automatic 4G/5G failover, so a fibre fault never takes your calls or card payments offline.
One migration, one supplier, one bill
- Voice, alarm-line SIMs, broadband and failover handled as one project, not three suppliers.
- Keep your existing numbers — ported onto Cloud Voice, typically in 7–10 working days.
- 30-day rolling terms on SIMs, so lines you replace aren't locked into a long contract.
- Managed support with one UK helpdesk for every service on the bill.

PSTN switch-off FAQ
What is the PSTN switch-off?
The PSTN is the UK's old analogue telephone network. Openreach is retiring it and moving all voice services onto internet-based (IP) connections. New analogue lines can no longer be ordered, and the network is scheduled to be switched off on 31 January 2027.
When do I actually have to move?
Before 31 January 2027. Anything still running on an analogue line — voice, alarm, PDQ, lift or fax — stops working when the network is retired, so migration needs to be planned well ahead of the deadline.
Will I lose my business number?
No. Geographic and 03 numbers port onto our cloud platform, usually within 7–10 working days, so your customers keep calling the number they already know.
What happens to alarm lines, card machines and lift phones?
Many of those devices can't run over VoIP. We replace the analogue line with a 4G/5G data SIM — a dedicated connection at a fixed monthly price, on a 30-day rolling contract with next-day delivery and no minimum order volume.
Do I need to buy new phone hardware?
Not necessarily. If you have SIP-compatible handsets you can keep them, or we supply pre-configured Yealink desk phones that arrive ready to call. Many sites run entirely on softphones from a mobile or laptop.
Can I keep my on-premise phone system?
Yes. SIP trunking connects an existing PBX to the cloud with channels that scale to your call volume, so you can move off analogue without ripping out equipment that still works.
What does migration cost?
Cloud voice licences start from £5 per user per month, and replacement SIMs are priced per line. Request a quote and we'll build your migration as a single proposal with one monthly bill.
Do you cover the whole UK?
Yes — we work UK-wide. SIMs ship next day, and broadband is available wherever Openreach fibre is live. One supplier, one bill, one support desk for voice, broadband, mobile and energy.
