2025 PSTN/ISDN Switch Off

Openreach is switching off the PSTN & ISDN network in 2025, so what does this mean for you?

In 2025 the final elements of the PSTN (analogue telephone lines) & ISDN (digital lines) network will be turned off with all IP (internet based lines) replacing these legacy services. The project has already begun, so do not hesitate to consider your options.
