Yet another thread as I run into another problem 
Anyone knows who is responsible for the wiring up to and including the master BT socket?
The BT engineer could get the line working up to the common point of my floor, but said it seems the final piece of cable connecting my flat to the common board in the small room were all the wires are is crushed and the copper leaks signals on all pairs!
I know the socket is "BT's property", but the wiring isn't? I thought I would ask here before arguing with BT if anyone has any experience of this sort.
Thanks a lot.
