The Openreach PSTN Withdrawal


Openreach have announced its decision to switch off its PSTN (Public Switch Telephone Network) services and products after weeks of consultation with communication providers.

The PSTN and ISDN withdrawal will affect both business and residential customers.

PSTN switch off - what it means for you

What services are affected by the PSTN switch off?

Services directly affected:

  • WLR (Wholesale Line Rental)
  • ISDN2 & ISDN30 (Integrated Services Digital Network)
  • Local Loop Unbundling Shared Metallic Path Facility (LLUSMPF)

Services indirectly affected:

The most affected services for the customer are voice services over a landline and broadband products (FTTC and ADSL) that run over a PSTN line.

Other products and services affected by the change are alarms and payment terminals. Customers should begin looking in to IP based solutions for these products before the PSTN network reaches end of life. They can do this by contacting their existing provider.

When is the PSTN shutdown happening?

Openreach have decided that the PSTN is aging and therefor will reach end of life in December 2025. Openreach have clarified that this date is set in stone and the deadline will be met.

They have also announced that by September 2023 they plan to stop supplying any new WLR services.

What will replace the PSTN network?

This PSTN withdrawal means that both residential and business customers must upgrade from using a landline to a VoIP (Voice Over IP) phone system to make calls.

Customers will also need to upgrade from ADSL or FTTC broadband to a new broadband product called SOGEA (Single Order Generic Ethernet Access) which does require a landline.

VoIP vs landline

A Voice Over IP phone system is (in my opinion) is a lot better than a landline when it comes to making and receiving calls. This is because, with most VoIP solutions you can intelligently route calls with its advanced features and UK call costs are (most of the time) included.

For more information on moving from a landline to VoIP see our article here.

Getting ahead of the PSTN withdrawal


Before December 2025, you will need to upgrade your current broadband if you are with a provider on the Openreach network and have FTTC or ADSL broadband. These need to be upgraded as they both are installed on a WLR line.

If you are looking to upgrade to the new broadband service that does require a phone line, get in touch here.


Customers will also need to migrate from using a landline to an IP solution such as a VoIP phone system.

We can port your landline number to our VoIP phone system within 10 working days.

See our telephony page for more information about our phone system.

Alarms and payment terminals:

Any services such as those listed above will need to be upgraded to an internet-based solution. You will need to contact your existing provider for more information about this.

To conclude:

After the recent announcements it is worth doing some research on how the PSTN withdrawal can affect you and how you can mitigate the impact of it. If you need someone to talk to about upgrading to SOGEA you can contact us here.
