I have the RJ11 adaptor for the switch over to VOIP, my telephone socket is wired directly into the external Virgin junction box. I need to know about the colour codes, in the box the virgin wires used are blue and white, the cable to my house socket is connected with blue/white, orange/white and white/orange, (I thought that only 2 wires were required), the RJ11 adaptor has 4 wires in the plug, orange, blue, green & white.
I want to use a salvaged phone plug, to plug into the adaptor and to be connected, via a terminal block, to the wire going to the home phone socket, this has wires red, black, green & yellow.
Does anyone know which of these four wires I should connect to the RJ11 plug/adaptor.
