Buy new socket, a length of telephone cable and some cable clips.
Daisy-chain the new extension socket by connecting Pin 2 on the existing socket to Pin 2 on the new one, Pin 5 to Pin 5, and Pin 3 to Pin 3.
It doesn't really matter which colour core you use, so long as you use the same colour at the other end.
Common convention is to use;
Pin 1 - Green & white
Pin 2 - Blue & white
Pin 3 - Orange & white
Pin 4 - White & orange
Pin 5 - White & blue
Pin 6 - White & green
Telephones use Pins 2 & 5 for conversation. Pin 3 makes the bell ring.
If you don't fancy that, you can buy an extension flex which has a plug at one end which goes into your existing socket (your exiting 'phone plugs into that) and a socket at the other end for your new 'phone.
