It's much easier to analyze if you send the original pcap files rather
than a text dump (we all have wireshark).  Even better, is to use the
internal message flow tracing in sipXecs - See:

http://sipx-wiki.calivia.com/index.php/Display_SIP_message_flow_using_Sipviewer#Getting_SIP_Messages_to_display

when you get the trace data, take a look at it using sipviewer and/or
post the trace with a description of your configuration (identify
components by IP address), what you were doing, and which call in the
trace you're talking about (by call-id or frame number in the trace,
preferably).
