I use the MCK key, then I go to the frame and listen for the lamp pulse. I find that the switch no longer sending the lpa signal, but the phone still flashes... I unplugged a phone this was happening to for 5 min. plugged it back in and it still flashed. After 30 min. it then stopped flashing and worked fine, however, the other 154 faults like this were not able to be fixed this way.
Tried:
DISU, ENLU
DELETING VM and re-enabling
made sure Call Pilot was sending the clear request
It all seems to come down to the type of phone, hard to beleive anybody else who gets this same upgrade isn't seeing this fault.
