What's Happening and When
Openreach is retiring the copper PSTN network that has carried UK phone calls for over a century. Here's the timeline every business should know.
Stop-sell in many areas
Openreach has already stopped selling new ISDN and PSTN lines in many UK exchanges. New connections are VoIP-only.
Full PSTN switch-off
All remaining analogue and ISDN lines will be permanently switched off. Any business still relying on traditional lines will lose service.
All-IP future
The UK moves to an all-IP network. Businesses on cloud phone systems and VoIP will be fully prepared and unaffected.
What Happens If You Don't Act?
Complete loss of phone service
Traditional phone lines will simply stop working. No calls in, no calls out.
Alarm and payment systems affected
PSTN-connected alarms, EPOS terminals, and fax machines will also stop functioning.
Last-minute migration headaches
Leaving it late means longer lead times for number porting, limited engineer availability, and rushed deployments.
Why Moving to VoIP Is an Upgrade, Not Just a Swap
The PSTN switch-off isn't just about compliance - it's a chance to get a better business phone system at a lower cost.
Cloud PBX with no hardware
Move to a hosted VoIP phone system with zero upfront hardware costs. Pay monthly, scale easily.
Better call quality
HD voice quality over modern broadband far exceeds what analogue PSTN lines deliver.
