All tele comunications are ending copper wire to the house telephones - the standard landline. Its replacement is the VOIP (Voice over internet prtotocol) that runs the equivalent of the old landline through your home internet.
BT tell you how wonderful this is, how it is so much better than a landline. You cannot stop them doing the changeover, what you do not need to do is believe all the bullsh*t about how much better VOIP is, because it isn't.
DH and I prefer to keep our mobile phones for personal and emergency medical calls and do our 'business' through the landline, now VOIP. Only this morning, a call was cut off half way through, this happens to at least a third of our calls. Some calls will get cut off several times and have to be redialled.
We had a week when we could not make external calls, although we could receive calls. The solution turned out to require us to turn our router off and turn it back on again.
We have not restored our ansaphone, nor several other services we had on our phones because they are so complicated to set up - and also complicated to access.
Plus, of course, if your internet goes down, so does your phone.
I can cope with the complications. I cannot cope with all those telling me that I am getting an improved service - we aren't.
