Hopefully the right place to post... I have a phone with a basestation which has an RJ11 port that connects via a cable to the BT style plug in the socket on the wall.
I'm trying to get rid of as much noise/interferance as possible, so was looking to get a shorter (and twisted pair if possible!) cable than the 2 meter one that goes between the phone and the socket at the moment (that came in the original box with the phone etc.). 30cm would be a perfect length, but looking online on Amazon etc. I can't find one less than 1 meter in length.
