The Ultimate Guide To Surviving The ISDN Switch-Off

It’s out with old, in with the new. By December 2025, all PSTN and ISDN phone lines on the national grid will be obsolete. That means the end of traditional landlines and the start of a new era – IP (internet protocol) telephony.

The UK is moving full steam ahead to a full fibre connectivity setup, upgrading from the copper wire infrastructure that’s been around for over 100 years. In many parts of the country, this is already done. Wherever you are in the UK, by 2025, you’ll no longer be able to make calls using traditional landlines. All calls will be routed over the internet.

What does the PSTN & ISDN switch-off mean for businesses?

All products and services relying on PSTN and ISDN lines will become obsolete – including huge numbers of traditional phone systems. This impacts non-voice services too, such as broadband lines including FTTC and ADSL. All these copper connectivity types will be withdrawn. It’s also worth noting that devices such as alarms, EPOS machines, door entry systems, CCTV, and faxes that use the old phone network system will no longer be operational.

It’s a lot to take in, but you can make your transition easy and stress-free with Ericsson-LG’s iPECS Cloud phone system. It centralises your business communications and provides valuable business tools, which we’ll discuss later.

It’s also completely internet-based – which makes it futureproof for the new, post-switch-off era in telecoms.
