How will the BIG BT SWITCH OFF affect your business? And what to do about it!

The BT 2025 switch off

Over the next four years the UK’s telecoms networks will undergo massive change with the Big BT switch off, shutting down BT’s traditional phone lines in favour of internet-based systems.

BT announced its big switch off in November 2017, stating it would not provide ISDN and PSTN services in the UK past December 2025, swapping all its business customers to VoIP (Voice over Internet Protocol) and SIP (Session Initiation Protocol) solutions. And, as of September 2023, BT will no longer sell ISDN or PSTN. This means from that date you will no longer be able to purchase or upgrade any new, or existing, PSTN or ISDN services. The final switch off of these services will be in December 2025.

After the switch off, all PSTN and ISDN service will cease to operate and there will be no maintenance available on any of these types of circuits.

Who is affected by the Big switch off?

As a result of the switch off over 16 million telephone lines will need to be transferred to IP-based networks which support broadband-based call services.  This will affect over two million UK businesses, with the biggest impact felt by those with a substantial use of landline telephones, alarm systems and other telemetry based services using PSTN lines.

Why is the BT switch off happening?

The PSTN has been in place for many decades and generally consists of copper telephone lines, fibre optic cables, microwave transmission links, satellites, undersea telephone cables and mobile networks. The PSTN is reaching the end of its life and becoming increasingly difficult and costly to maintain.

Over the last decade there has also been a huge reduction in customers actually using PSTN and ISDN services because they’ve already migrated to new IP telephony solutions. Today, there are plenty of other methods of voice and data transmission available that are cheaper, faster and more reliable.
