Digital voice seems to offer few if any advantages over the normal analogue 'phone service. It is evident from my conversations with BT personnel that even employees do not fully understand the way in which digital voice works. I live in an old house with very thick stone walls, and I was assured that digital voice would solve existing landline connection problems that I have in parts of the house. I have resolved internet wireless connection issues by installing a mesh network. I was told by BT employees that the digital voice range could be extended by using BT's WiFi discs. This is not the case. Digital voice is a DECT system that requires all phones to be able to connect to the BT hub. My advice to people thinking about switching to digital voice is DON'T. You will lose the ability to drop the local area code when you dial local numbers. You will have to connect older phones directly to your hub (or use another connector) if you want to use you old answerphone. The DECT range is not what is claimed when walls are taken into account. And, of course, if your broadband goes down, you will have no landline connectivity.
