This house is old and the wiring house is a mess. There are two almost inaccessible old fashioned UK style phone sockets located together behind a desk. The phone plugs into one and this works ok, the broadband is the other socket, but I don't know if it is on the same wire as the phone. If I plug the phone into the broadband socket it is silent, no dial tone. I can't find the BT master socket to test the connection from there.
