Re: [Freeswitch-dev] Call to registered phone behind NAT
Hi, I little narrowed problem with NATed client.

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. -MC Sent from my iPhone On May 25, 2010, at 10:08 PM, Oleg Khovayko <khovayko@gmail.com> wrote:
