Digital voice with copper line

fredc — Thu, 04 Jun 2026 08:50:23 GMT

I'm due to get changed over to Digital Voice soon and still have a copper line, I'm aware of linking my current phone network (extensions) to the green socket on the hub to my master socket with a phone patch lead to keep the network active, but I've been told by a guide that my extensions will become redundant. I would be grateful of any advice please, I've searched the forum but couldn't find an answer. Thanks. Fredc.

A short summary is:
If you're on DV but still get broadband via FTTC and a copper line, then you can't connect the green socket on the hub to the BT master socket because that is still providing your broadband. There are too options:
1. Separate your extension wiring from the BT master socket and connect just the extension wiring to the hub green socket.
2. Instead of your extension sockets, use what BT confusingly call "DV adapters", which are really portable phone sockets that plug into electricity outlets anywhere in the house and connect to the Hub via DECT.

Thanks Crisjp, That's what I need to know, separate the extension wiring as the master socket is still in use for the broadband connection on the copper line, the guide couldn't tell me that, they're sending me an adaptor as well so should be covered. Thank you. Fredc.
