Broadband and phone provider BT<\/a> (EE<\/a>) has today revealed that the majority of its landline phone using customers, over 3 million UK households, have now successfully switched to its IP<\/a>-based Digital Voice service. But there’s still more to go ahead of the analogue phone switch-off in January 2027. Some 80% of BT<\/a>’s business voice customers have also switched.<\/p>\n

Just to recap. The legacy phone switch-off was previously delayed to 31st January 2027<\/strong> in order to give broadband ISPs, phone, telecare providers, councils and consumers more time to adapt (details<\/a>). The main focus of this was the 1.8 million UK people who use vital home telecare systems (e.g. elderly, disabled \u2013 vulnerable users), which aren\u2019t always compatible with digital phone services because telecare providers were slow to adapt.<\/p>\n

NOTE:<\/strong> Openreach<\/a> are withdrawing their old Wholesale Line Rental (WLR) products as part of this change, while BT are retiring their related Public Switched Telephone Network (PSTN).<\/div>\n

Nevertheless, BT is known to account for a significant portion of UK landline phone services and so the news that they’ve already been able to switch 3 million households to their broadband-based (IP<\/a>) phone services (Digital Voice<\/strong>) represents good progress. But the provider doesn’t clarify how many households are yet to make the switch.<\/p>\n

BT claims that the majority (99%) of handsets should be compatible with their digital landline service, while customers will “generally keep their existing number and pricing<\/em>” when moving over. Extra protections are also available for vulnerable customers, including free engineer visits and backup (battery) power where required.<\/p>\n

Allison Kirkby, BT Group CEO, said:<\/strong><\/p>\n

“Upgrading the UK\u2019s digital backbone is essential to make sure everyone has the modern, secure and resilient connectivity they can trust to help them prosper in a connected world. Failing, decades-old infrastructure holds back homes, businesses and digital inclusion ambitions.<\/p>\n

BT is currently one of the biggest investors into UK infrastructure and will have invested more than \u00a340bn into the country between 2020 and 2030. We know that growth and opportunity is unleashed, as a result of our investment and when people, businesses and communities connect to our digital networks.”<\/p><\/blockquote>\n

However, Openreach<\/a> recently confirmed that there are currently still c.2.8 million lines on the old phone network that need to migrate (across all providers), with more than half a million of those serving business premises. The operator has also previously stated that prices for these legacy lines are set to double by October 2026 (details<\/a>), which is another good reason not to leave upgrading until the last minute.<\/p>\n

In the final year of the nationwide upgrade, BT are thus today reminding customers of what support is available and warning that “failing to respond to messages from their provider may result in disruption to their phone or broadband services as the switchover deadline approaches<\/em>“.<\/p>\n

In most cases such upgrades merely involve a fairly seamless change of service by your ISP, which often results in you needing to connect your home phone into the back of either a broadband router or small Analogue Terminal Adapter<\/strong> (ATA), instead of directly into the NTE5A\/B\/C socket on your wall or skirting board. Special solutions also exist for telecare users.<\/p>\n

Just to clarify something that catches a lot of people out, only the PSTN phone service is being removed \u2013 copper lines still exist and can also handle digital IP-based voice and broadband services, so this isn\u2019t just about the wider switch to full fibre (FTTP<\/a>) lines, yet.<\/p>\n","protected":false},"excerpt":{"rendered":"
