I wasn't really sure if this was the right place to put this but im sure it will be moved if not.

Im having troubles with one of the phone jacks in my house. It will only work when i use a cord which only has the 2 wires in it (Green & Red) As soon as i plug the cable with 4 wires it won't work. (I have opened the Jack up and it only has 2 wires running into it)

Is there anyway to solve this problem? I really want to run a double adapter through it but all the ones i find have 4 wires and they won't work.

I've checked all the other phone jacks in the house and they have 2 wires coming in also. Except one which i presume is the master it has 4 wires?

Can someone point me in the right direction here?
