So you know mine. What are your thoughts ?
I think that a significant minority are still attached to their landline phone numbers - perhaps mainly in the older demographic, but there is a lot of those. And the vast majority of people of all age ranges are non-technical.
I think it's going to cause annoyance if people are told that they'll lose their phone number on (forced) migration to FTTP; but it will be worse if they lose their phone service without realising it in advance, and on top of that find their number can't be recovered. Many people will assume that their phone number will remain as part of the service, because, isn't it obvious that it should?
At very least then, these providers must make it *very* clear in advance that this will happen, and what the available options are.
From the service providers point of view: the big winners here are likely to be BT, because the simplest solution for many in that situation will be "switch to BT". It will be harder for the likes of Sky and Vodafone to get the message across that migrating to *them* will also solve the problem.
Of course, Plusnet doesn't really care about losing customers to BT. That really leaves only Talktalk out of the major providers that don't yet do voice with FTTP, and I believe they have some solution under development. if they get it ready in time, then most of the problem is gone.
Voice has never really been a priority with Talktalk though. Some years ago, I knew someone who worked for Talktalk (actually quite senior in network operations), who moved house within the same area and for whom keeping the phone number was important. His line was with Talktalk, but they were unable to move the number to the new property; they simply didn't have the process in place to allow this. So he was forced to move his line to BT, then move house, and then at the end of the BT contract move it back to Talktalk.
