The great BT ISDN Switch Off is here

BT intends to switch off the PSTN and ISDN networks for good. This switch-off started in 2020 with a cease in supply, moving to complete migration by 2025.

The BT ISDN switch off could affect many practices soon, especially those unaware of BT phasing out ISDN and looking to invest in or upgrade their current telephone system.

How to prepare for the ISDN end of life

If you currently have a traditional ISDN/PSTN-based system, now is an excellent time to look into the alternatives. The BT ISDN switch-off marks the next evolution of telecommunications technology.

If your practice still uses ISDN or analogue, you can switch comfortably to VoIP telephone solutions with Microminder. Your number can be ported and retained, and the whole service can be set up within weeks.

I’ve got until 2025 – what’s the rush?

You may think you have until 2025 before the big switch-off takes place. However, major phone providers are currently reporting a 3-5 month backlog and anticipate this will increase as the deadline approaches. You could be left without a working phone if you do not act quickly!

Luckily, Microminder has a team of expert engineers on hand to make the transition as straightforward as possible.
