[Freeswitch-dev] Call to registered phone behind NAT

Tue May 25 22:48:19 PDT 2010

If you have a web server then use tcpdump to make a pcap file that we  
can download and analyze with Wireshark. Check out this page:
http://wiki.freeswitch.org/wiki/Packet_Capture

For some hints on how to collect pcaps in a FreeSWITCH environment. It  
can be difficult to do a siptrace on the conole. Also, you can rotate  
log files with "fsctl send_sighup" which can help isolate log data.  
Alternatively you can use logger.pl script in the source support  
directory.
