I've got a problem identical to the one described in thread940-1138614, and haven't been able to figure out the cause.
I've got a 4622SW phone plugged into our voice network, and it was functioning correctly until I upgraded it to the newer version of firmware that was released in February 06. Now it boots up, asks for an extension number and then give a blank screen. MUTE-R-E-S-E-T, V-I-E-W, C-L-E-A-R, etc all work fine, but the phone itself is unreachable, and can't make outgoing calls.
I've tried forcing the thing back to the older version of firmware (Nov 05 I think), but that doesn't seem to change the problem at all.
Any suggestions?
Thanks,
Andrew
