Re: dect phone problems!
 

How many wires are connected up in the master socket? You'll have to unscrew it from the wall to tell us.

What colours and to which numbers
e.g.
1 - Blue / White
2 - White / Blue
3 - Orange / White
4 - White / Orange
BTW - this is an example, not how it actually is wired. Pritch can probably answer that in his sleep. Me I need the card that came with the tool for pushing phone wires into phone sockets (and why don't you get one of those on your swiss army knife?)
