Soon to be repeated in the UK, by the end of January 2027. We've now passed the tipping point where doing telephony end-to-end entirely over IP is cheaper that keeping the baseband analog PSTN going. The main network backbone, of course, has been all-VoIP for years.
It's taken British telcos years to plan for this, and it's been put off a couple of times to deal with practical problems such as situations where you absolutely can't put fiber-to-the-premises in in any reasonable timescale.
This time they really seem to be determined to make it happen, even if it involves bizarro products like SOGEA, and if I recall correctly a sort of exchange-hosted baseband-only single-line DSLAM for the most intractable cases such as elderly people with no access to mains power - but even then it will implement the standard Digital Voice protocols, not the legacy DSLAM stuff.
What are the plans for people who can't get fibre to the property?
Over the past couple of years, my parents have had several multi-day outages with their phone line. Each time, we contacted Sky, who contacted Openreach and they eventually fixed things, but then it would stop working again months later.
I guess they're just not maintaining that infrastructure like they used to.
Finally my parents succumbed and now their phone is plugged into their router.
