<br><font size="2" face="sans-serif">I want to verify I'm reading this debug
correctly before I throw everything I have at Telco. Intermittent
calls are getting disconnected during the conversation mid-sentence. Every
one of these that are reported, I match up the CM traces with the debug.
I see the call comes in with the below SETUP message and I use the
callref = to find when the call ended. All calls say Normal call
clearing. Does the RX <- DISCONNECT mean that either Telco or
the customer hung up first?</font>

means our side hung up the call first.</font>
