BT Synergy 3505 - no dialling tone / incoming calls?
I have a BT Synergy 3505 trio home phone. Whenever I try to make a call, there is no dialling tone, plus when I phone the number, it just rings and rings on the line, but the phones don't ring or seem to recognise there's an incoming call. Phone line is fine as internet and other phone working.
