Trying to find out why I have some 7960's de registering by themselves...
Wireshark shows keep alives at the regular intervals... then all of a sudden, 2 seconds after the last keep alive I get
a Skinny un-register message from the phone to the CCM . Then a FIN from the phone to the CCM and a FIN from the CCM to the phone.
i've attached the capture of packets for people here to see.
right now the phone is on SCCP 8.0.7, i've tried 8.0.5 as well, still happens.
the system has 25 phone's on it, it's definatly not over burdened.
in RTMT the trace is showing a reason code of 8 for why it deregistered -- which is missing Keep alives... I'm expecting that, because the phone closes it's connection and stops sending -- so the CCM kills the connection.
The phone comes back by itself after about 3-4 minutes...
