Thanks but the hub is wired to the computer (upstairs in study) and the master socket is downstairs in the dining room.
I did not think the adaptors plugged into the existing sockets would work but VM said they would and made no reference to needing wiring. The route from the study to the dining room would mean cables all over the place - under carpets, along the edges of the stairs, round door frames preventing doors closing - the rooms are just not near each other. Also from when they wired in the hub their focus is on speed of job not tidy wiring out of eyesight.
It isn't practical to carry a cordless phone about the house - in the same way no-one really carried around "mobile" phones in the early 1980s - they're too large and it would be bound to be put down somewhere and then inaccessible in an emergency. I also find there buttons too small: I have large-button handsets for my landline so I can see what I am doing.
I did read (whilst trying to find if someone else had this issue) on this board that the switchover can be delayed until 2025? Which would at least give VM a chance to catch technology up with what is actually needed by some people?
Is everyone (ie all suppliers) going to VOIP because I'm assuming in some parts of the country this won't happen - there are areas VM doesn't cover and in some of those areas there isn't a reliable mobile signal, so I am assuming those places will have another provider who will stick to traditional landlines?
