Hello,
I'm trying to set up opensips (v2.2.2) and rtpproxy (2.0.beta.20150106)
one the same server, using loopback interfaces.
------------------------------
network config :
lo:2 : inet 111.122.100.18/32 (SIG address)
lo:4 : inet 111.122.100.20/32 (MEDIA address)
eth1 : 192.168.157.121/24
routing :
222.251.208.61 via 192.168.157.1 dev eth1 src 111.122.100.18
222.251.120.61 via 192.168.157.1 dev eth1 src 111.122.100.20
------------------------------
opensips setup :
listen=udp:0.0.0.0:5060
loadmodule "rtpproxy.so"
modparam("rtpproxy", "rtpproxy_sock",
"unix:/var/run/rtpproxy/rtpproxy.sock")
#routing
...
if (is_method("INVITE")) {
t_on_reply("handle_nat");
$rd="192.168.157.141";
if (has_body("application/sdp"))
{
rtpproxy_offer("afeiroc");
}
}
onreply_route[handle_nat] {
if ( has_body("application/sdp") ){
rtpproxy_answer("afieroc");
}
}
...
------------------------------
rtpproxy setup :
/usr/local/bin/rtpproxy -s unix:/var/run/rtpproxy/rtpproxy.sock -u
rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.157.121
111.122.100.20 -d DBUG LOG_LOCAL5 -m 10000 -M 20000 -w rw
------------------------------
When I'm making a call from 222.251.208.61 :
- INVITE arrives on the external side of opensips (111.122.100.18), SDP
contains 222.251.208.61:18592
- INVITE is relayed on the internal side to 192.168.157.141, SDP is
modified to 192.168.157.121:17226
- 200 OK : 192.168.157.141 replies with a 200 OK, SDP contains
192.168.157.141:12704
- 200 OK : opensips relays 200 OK to 193.252.208.61, SDP is modified to
111.122.100.20:17826
So everything looks good in the SDP.
Now looking to the rtp streams :
stream from 222.251.208.61:18592 to 111.122.100.20:17826 : OK
stream from 192.168.157.121:17226 to 192.168.157.141:12704 : MISSING
stream from 192.168.157.141:12704 to 192.168.157.121:17226 : OK
stream from 111.122.100.20:17826 to 222.251.208.61:18592 : OK
It seems that rtpproxy fails to bridge the "external -> internal" part
of the media.

I can't figure out what's wrong in my config. Can you please help me ?
Should I post this message on rtpproxy mailing list too ?
Best regards,
Cédric
