In the biggest change to the telecoms industry for over 30 years, BT announced back in 2015 that they’ll be switching off PSTN and ISDN in December 2025.
What does that mean in non-technical speak?
They will no longer be using infrastructure that currently supports landline calls, so businesses and home users alike will have to switch to internet- based services (VoIP) in order to still be able to make calls. This change will also affect some payment terminals which run using a phone line.
There isn’t a published plan yet for how the legacy services will be withdrawn in 2025, but it’s good to be aware of if you’re considering implementing a business communication strategy that stands the test of time.
