Hello,
do you use something for nat traversal in kamailio config? Is the
re-INVITE handled properly?
There might be a deadlock if the endpoint behind the nat is not sending
any RTP packet, then the rtp relay (being it asterisk or rtpproxy)
cannot learn the port in the nat router where to send the fax.
Cheers,
Daniel

Dear All,
I'm trying to send FAX to an endpoint Behind NAT...The scenario i the
following:
PSTN_GW-->Asterisk-->kamailio-->Endpoint behind NAT..
The FAX is failed and I got the following error log on asterisk:
Mar 20 09:21:09] WARNING[20388]: chan_sip.c:12409
handle_response_invite: Re-invite to non-existing call leg on other
UA. SIP dialog '76c64f8373def68d5088690816c67493@Asterisk_IP'. Giving up
On kamilio everything looks great except the received value in the
INVITE message...I guess it should be the Public IP of the endpoint
and not asterisk IP address...
Can you please help me in order to find the real issue? the log is
under http://pastebin.com/d1e7ba841
