We had A power outage and when the power came back on only one phone(X100) is ringing in. We have four more phones which would all ring and could be answered before.We have 3 lines on the system which can all be used to call out.The back-up battery was low so I think we lost the programming linking the phones. I downloaded an adminstor's manual but still don't know if the other four phones were extensions of the first phone or in a hunt group. I can't figure out from the manual how to reprogram the system for either.
The system is old and the company which originally installed it is gone. I have been able to program some features from the manual (Time and Date) and (Trunk group for stations but don't really understand that) so I think there is no hardware damage. I need to get all my phones back on the same page so they all ring and can be answered by whichever phone is picked up.
