Everything you need to know about the PSTN switch-off

What's happening?

The UK’s traditional phone network will close at the end of 2025.

 

By then, every phone line in the UK will have moved to a fully digital network that uses Internet Protocol (IP) across a fibre-based service. The change affects the Public Switch Telephone Network (PSTN) and Integrated Services Digital Network (ISDN).

 

We’ll be switching all our customers who use our existing phone service to a fully digital service before then. It means that fully digital networks using Internet Protocol (IP) will replace the traditional phone lines used for calls and data services.

 

Make the move early and it’ll be business as usual.

In the run up to 2025

To help make this possible, Openreach is busy rolling out the full fibre network (fibre to the premises or FTTP) in phases across the UK.

 

It means that once an exchange area is over 75% full fibre-enabled, we’ll stop selling traditional phone line services to new and existing customers at fully fibre-enabled premises. By September 2023, we’ll stop selling traditional phone line services altogether. 

 

But if you decide you don’t want to move to a fully digital network just yet, your current service will still work as it does until the switchover.

How does this affect my business?

Along with upgrading your broadband and phone services, you’ll need to identify everything that connects to your phone lines as devices and equipment that currently uses PSTN and ISDN networks will also stop working. 

 

Here are some common examples (not an exhaustive list): telemetry devices, alarms, EPOS machines, faxes, and so on. 

 

If you use products or services that work using our phone network, this is for you. You'll need to contact the provider of those devices to check that they'll be compatible with the digital network - or you'll need to upgrade them.

Why’s this happening? And why now?

The PSTN and ISDN networks are old and difficult to maintain. They’re essentially a 20th century technology that can’t keep up with the demands of modern-day communications. We all expect much more from modern phone services than the traditional technologies can deliver. 

 

And it’s not just us: the switch to digital is happening everywhere, fast. Germany, Japan and Sweden are ahead of us in making the shift. Estonia and The Netherlands are already there and have decommissioned their PSTN networks.

Things you need to know

Terms, conditions and legal stuff

Can I take and make calls on any device?

In most cases, yes.

As long as there’s adequate connectivity and suitable hardware with the right system requirements.

Can I add new users if I need to?

Administrators have real-time access to the services through an online portal that can be securely accessed across the internet. 

Depending on the volume of users contracted to, the administrator can add, change, and remove users as they need.

Can I access customer information whenever I want?

Yes, provided that there’s adequate provisioning and access rights have been enabled.

Many BT cloud communication systems can be integrated into line-of-business applications that give end users a real-time view of customer information.
