I have been under the house and tried to reconnect these wires, however I haven't managed to fix the problem. I have followed the phone line in from the street and this was the first phone jack of the three in the house. The other two were also wired into this one, hence why they are dead too.
We have always used the phone jack in the bedroom and don't really need more than one phone jack in the house, so I have rewired the jack in the bedroom with the cable that comes into the house from the street (so there is nothing between the two points). I have replicated the wire placement as it was before, however I'm still not having any luck. Having read other forums online it appears that the wiring we have isn't very common? There are six wires (red, white, orange, black, green and blue)
I have uploaded a photo showing what I have done.

Red wire in the '5' slot, white in the '2'
Please help!
