<div>See my post entitled '"show voice trace" and
"battery-reversal answer"' which no one responded to yet and
I really think might be relevant.</div>
<div><br></div>
<div>There are states and events for the FXO port in question that
"show voice trace" that I saw when I was having a similar
problem. If this is the cause then it has nothing to do with the stuff
your debugging, but rather with errors at the FXO state machine level
which are propagating (back).</div>

<div>Does this make sense or am I way off track?</div>

I can't really tell if that is the h225 or h245 session being
aborted. I'm guessing h245 since the router still composes a
RELEASE_COMPLETE message to send over h225. But it could be that
the router only received a TCP FIN on the h225 session, so it could
still send data to the CM.</font></blockquote>

just reset TCP sessions out of the blue. Turn on the h245
decodes in CM traces and turn trace level up to
detailed. Maybe also get a sniffer trace (microsoft netmon
is installed on win-os images) to see if the TCP FIN/SRT is
originating from CM or maybe an intermediary
device.</font></blockquote>
