I'm have a phone extension lead that I then plug the phone in to but want to replace it with just one wire. The bit that plugs in to the phone is rj11 2pin with a 4pin phone end that plugs in master socket.
Do I need a 4pin cable, or a 2 pin for me to do this also cross over or straight
Tock pick of the phone back etc.
