The UK’s PSTN network will switch off in 2027

BT plans to discontinue ISDN and PSTN services in 2027. But what is going on, and how will the switch-off affect your business?

BT’s press release said this:

"Following the industry-wide pause to non-voluntary migrations in December 2023, we now expect to have migrated all customers off the PSTN by the end of January 2027, allowing us to align the programme with full fibre broadband customer upgrades where available."

What’s happening?

UK telecoms provider BT is moving all their customers from the old analogue public switched telephone network (PSTN) to a fully digital network. They've already started. They plan to have moved everyone over before Openreach stop the PSTN (and ISDN) service in 2027.

By then, every phone line in the UK will be digital, routing calls over IP (Internet Protocol) rather than the traditional PSTN.

What do I need to do?

If you currently have a traditional ISDN (Integrated Services Digital Network) or PSTN (Public Switched Telephone Network) based system, now is a good point to look into the alternative.

Although there is plenty of time until 2027 rolls around, it’s best to plan ahead and you may actually find you want to migrate sooner rather than later after finding out all of the benefits the replacement internet-based systems have to offer your business.
