Hi Justin,
Typically when you see the message "StationInit - Keep alive timeout"
in the trace it is coming from CallManager. It seems strange that it
would be a StationInit message but the timeout is coming from the
StationInit process within the CallManager. CCM/SDL traces from the
same time frame may help to confirm this. A packet capture of the
problem would be best though.
At some point, don't remember when, the KeepAliveAck message was taken
out of the CCM trace. One thing you can do is to go backwards in the
trace from the "Keep alive timeout" message and see when the last
KeepAlive from the phone was. I suspect you will find one missing.
HTH,
Kevin
