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). _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users
