Also known as Digital Voice, the project is underway and the impact is already being seen at premises across the UK.

The UK’s analogue phone service is undergoing significant changes. PSTN lines have already started to disappear, which is affecting older signalling systems that rely on analogue lines. Over the coming months, this is set to ramp up and as soon as June 2021, over 1.2 million premises are estimated to be affected by All IP. By January 2022, this figure will rise to over 2 million. 

The table below shows the priority exchanges that Openreach have confirmed will be involved in the first tranches of the project. As part of the project’s trial, Salisbury was the first area to move into the ‘stop sell’ stage in December 2020, which means no new PSTN connections are now available in this area. The next 117 exchanges will transition into this stage from June 2021, with a further 51 being added in October 2021 and again in January 2022. These, combined with Salisbury, will see 220 exchanges start to migrate to the All IP Network within the next 12 months.
