The UK's copper phone network is being switched off. If your business still relies on PSTN lines, ISDN circuits or landline-dependent broadband, this page is your starting point for what replaces them, and how to move without disruption.
It's not just phone lines. Anything that quietly relies on an analogue connection is exposed:
None of this fails gracefully. When your local exchange migrates, unmigrated services don't get a warning, they simply stop. For phone lines that means lost calls. For alarm signalling and lift lines, it can mean a safety-critical system going silent without anyone noticing until it's tested. Planning the move now, rather than reacting to an outage, is the difference between a managed project and an emergency call-out.
We map every PSTN and ISDN-dependent line and service across your business, including the ones nobody remembers are still on copper.
We match each service to the right replacement - SIP trunking, FTTP, SoGEA, hosted voice, or resilient 4G/5G backup - based on what you actually need, not a one-size-fits-all switch.
We test the replacement on a small site or line group first, checking call quality, failover and number routing before wider rollout.
We coordinate the wider migration, port your existing numbers, and schedule changes to avoid disruption to calls or connectivity.
Once you're migrated, we monitor and support the new setup as part of your existing Wavenet service.
Fire and intruder alarms, lift emergency phones, door entry systems and other connected devices often rely on the same copper lines as your phones, and they're just as exposed. The principle is the same as the rest of this page: replace the analogue line with a resilient digital connection, typically 4G or 5G backup sitting behind your existing signalling equipment. If you're not sure which of your critical systems are still running on copper, that's exactly what the audit step above is for - talk to us and we'll help you work out what needs attention and in what order.
