ISDN Switch Off

From 2023 there is a hard stop-sell on traditional phone lines, known nationally as the ISDN Switch Off. From 2025 the network will be ceased entirely. You will need to upgrade your phone system as soon as possible to avoid any disturbances to your business. Don’t worry, switching now is likely going to save you a lot of money!

What is the ISDN switch off?

Put simply, many current phone, CCTV and even security systems run on a copper based PSTN and ISDN network. This network will be turned off in 2025. This means any systems you currently have using these lines will cease working. You will need to switch to handsets that can use IP (internet protocol).

Don’t panic, most businesses will save money by switching to Virtual Numbers, so many have already made the switch to a future proof system.
