[SR-Users] Kamailio and rtpengine - client behind NAT
Martin Schiøtz
malinux at gmail.com
Fri Apr 24 00:01:21 CEST 2015
I did try rtpengine_manage() but rtpengine still saves 10.0.0.100 in redis.
I did also try without asymmetric with no luck.
I changed flags in my rtpengine_answer() and rtpengine_offer() to
"replace-session-connection
replace-origin" that saved the public ip correctly and forwarded SDP
correctly. The call is now established
Now I have problem when the remote user B-end hangs up. Why would kamailio
188.166.3.25 just send the BYE message back to 188.226.200.111 instead of
sending it to 80.71.132.X A-end behind NAT?
(the last 4 packeges in the dump)
The problem must be aroung t_relay() ?
Cheers,
Martin
