Preparing for the
PSTN switch-off in 2027

Hands-on support to ensure a seamless transition to
IP-based communications

In 2018, BT Openreach announced that the Public Switched Telephone Network (PSTN) would be retired in favour of Internet Protocol (IP)-based alternatives by January 2027. Legacy PSTN solutions are therefore being phased out, which means solutions that depend on these connections will need to have an alternative in place before the final switch-off. With 33% of large organisations reliant on the PSTN or ISDN networks to some extent[1], it is essential that they have an alternative solution in place by the designated switch-off date.

Future-Proof IP Solutions

Why are PSTN services
being phased out?

The copper network has long served as the foundation of telephony across the UK. However, it has become increasingly difficult to maintain. Furthermore, compared to newer technologies, its limitations with regard to security, reliability, and bandwidth have become increasingly clear.

What advantages
will IP-based communications offer?

IP-based solutions can be scaled up or down as necessary, without additional hardware needing to be deployed.

How will the stop-sell affect you?

As part of the transition to all-IP services, BT have instituted a stop-sell of new WLR services, which took place on September 5th, 2023. As a result, no new deployments of these services will take place, which means you must be aware of the alternatives and develop your VoIP phone system accordingly.

As the FTTP priority exchange stop-sell is rolled out in specific regions, FTTP will be the only option available. In regions where this is not yet the case, transitional solutions - such as SoGEA - will be available from your VoIP provider instead.
