I have a phone jack in the study, to which a phone and the ADSL broadband router connect. It is a bog-standard BT plug.All was working fine.
My klutzy partner has somehow managed to give the phone an almighty yank, which has literally ripped the jack off the wall.
So I have half the jack, with the phone plugged into it. The other half of the jack is still attached to the wall, with a red wire and a white wire hanging out of it. It looks a bit like this, but with just the red and white wires hanging free.

I am assuming I can (hopefully) just re-wire the red and white wires back to the jack, and screw it together again.
My question is how/where do the red and white wires connect back to the jack, and do I need any sort of special tool to do this?
