I have an old BT dial phone which worked perfectly till we moved and someone cut the wire going into the wall leaving about a metre coming out the back of the phone. I have established that it needs a BT431A phone plug to connect to the wall socket BUT......... The cable is round, not 'D' shaped, which I do not think is a problem, but the colours are: there are four wires, Green/Blue/Red/White. Does anyone know which order they should be fitted into the phone jack, and would it matter if they are wrong? If not, does anyone know where I could find someone who does know? BT have got no idea what I am talking about!!!!!!!! Is there an 'Old' (with respect) BT engineer out there who knows about these things? Many thanks for any advice offered.
