PSTN Switch off

We are now living very much in a digital world and PSTN (Public Switched Telephone Network) is an analogue complex system that is no longer fit for businesses and personal use So, in December 2025 this service will be switched of permanently in the UK by BT and everyone will be using IP (internet Protocol) or VOIP (Voice over Internet Protocol) which is where broadband or mobile data is utilised.

December 2025 may seem like an age away, but migrating over to IP services now means that you can ensure you, your staff and your business will not notice the switch off at all. Calder IT can make this transition as painless as possible. You may not realise what is connected to the PSTN, but Calder IT will ensure that any alarm systems, emergency points of contact or hardware utilising PSTN is migrated over to IP services too.
