Caller ID shows name unavailable out of area, even though the number shows up on all the phones. It also locked up today I relized it when I walked downstairs and i heard the turbo prop fan they have in there going full throttle. Tried a power button reset 622 was unresponsive. Had to pull the plug and plug it back in.....
Try testing your caller ID and see if you have the same problem
