Ever since 1876, the PSTN network has been in operation ensuring that we all have communication methods that are fit for purpose. Until now, the PSTN network has served millions of users, and with technological advancement growing increasingly quick, it’s not surprising the network is now old and in-efficient.

From December 2025, the PSTN network is reported to reach the end of its life and will cease to exist from then.

Whilst this network is made up of single lines, it also supports several other products like ISDN2 and ISDN30, and therefore from December 2025, these connections will also cease.

What should I be doing to prepare?

The telephone network as you know it is made-up of single copper lines, which is now not fit for purpose in the way in which we communicate now-a-days. Services like VoIP are increasingly popular but they do need a good reliable internet connection to run seamlessly. VoIP (Voice over Internet Protocol) is the new breed of telephony communication, allowing you to be flexible and work remotely and seamlessly.

If your telephony is currently running on PSTN or ISDN, then you really need to start looking at upgrading this onto the VoIP network. For a free complimentary telephony review, simply schedule yours today by calling us on 0330 094 0170.

What happens with my internet?

More than likely your internet will be running over the same copper line as your phone line, and therefore your provider will be contacting you in due course to arrange the migration of this service.

Your broadband is a crucial element to the PSTN and ISDN switch off, meaning that you need a single order broadband in order for your VoIP system to work seamlessly.

Whats the timescale?

In 2023, BT Openreach report that they will not be supplying any new PSTN lines or ISDN.
