The old telephone network still works when there is no mains power, and I am not sure this IP everything is a good idea. During a power cut to an largish area, there will be NO telephone communication as most of the infrastructure is not battery backed up if everything is electronic. Accident or fire will happen but no communications from the public? Sounds like a disaster waiting to happen. Now does everyone see why "proper" electricity supplies are vital?
Battery backed up VOIP boxes are supposed to be available for people who rely on the land line phone. But customers may have to specifically ask for one.
Most people have a mobile phone these days and would use that if the land line goes down.
Of course that assumes the power cut does not affect the base station the mobile connects to. - given the short range of mobile phones, after all the average transmitter power is only a fraction of a watt, you are likely to lose the mobile connection and mains and fibre pretty much all at the same time, certainly for an HV side fault or a rota power cut.
