We have moved into a house and have phone sockets in one part of the house working fine but other phone wall sockets are dead - used to be two separate lines.
We were told by Swisscom that they can send someone to connect the two 'branches' in our house together, or can do it ourselves. As a DIY'er and used to UK phone wiring etc, I would to do this myself.
One box near the incoming line looks like it has two sockets - so wonder if that is where some briding connections are needed. I have taken the cover off and see grey blue green and purple connections as shown in the photo. My instinct would be to put two jumpers (the wire kind) to bridge between grey<->green and blue<->purple.
But if this is the main box I would have expected more wires. i.e. incoming swisscom & outgoing to other sockets...
Has anyone done this themselves and can advise?
