i have configured CUCM 8.5 and 50 CIPC, almost all of them works well but 5 softphones have the problem below:
Invalid SCCP message! : Invalid length = 335544320 - close connection and alarm in future
all CIPC are configured in the same location. These CIPC get loaded without any problem but in phone display is only shown hour and date not extension or soft keys. I have tested in another PC with same info device, it works. Into CUCM the fail phones are registered.
How could I solve this problem?.
