If you speak to family and friends on Zoom, Skype or Whatsapp, you're likely already using the new system. With this in mind, let's take a look at what will replace them. In order to meet the growing need, BT plans to retire both PSTN and ISDN by the end of 2025. There's no doubt about it: the current system is ageing fast.ĭue to more complex demands, the network is struggling to keep up. However, even these digital calls still depend on the old PSTN circuits. This digital network, known as ISDN, has all but replaced PSTN.

Whether you're a tech-whiz or a novice, this guide will explain everything you need to know about the switchover. This change will affect homes and businesses throughout the UK, including Lifeline equipment, but there is no need to panic.
