[OpenSIPS-Users] RTPProxy + OpenSIPS 1.7 Integration
Hello Everyone,
I am having trouble getting the RTPProxy 1.2.0 to work with OpenISP 1.7.
Starting the proxy using:
./rtpproxy -s udp:127.0.0.1:12221 -l public/private -p
/var/run/rtpproxy.pid -u root root -F -d INFO LOG_LOCAL0
opensips.cf relevant pieces
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:12221")
modparam("rtpproxy", "rtpproxy_autobridge", 1)
modparam("rtpproxy", "rtpproxy_timeout", "0.5")
modparam("rtpproxy", "rtpproxy_retr", 3)
if (has_totag() && is_method("INVITE")) {
engage_rtp_proxy("ie");
}
if (is_method("ACK") && has_body("application/sdp")) {
rtpproxy_answer();
}
route[1] {
xlog("Enter route 1");
if (has_body("application/sdp")) rtpproxy_answer();
if (is_method("INVITE")) {
xlog("New Call for route [ fu=$fu/ tu=$tu /ru=$ru/ ci=$ci]");
if (rtpproxy_offer()) {
t_on_reply("1");
}
else {
t_on_reply("2");
}
t_on_branch("2");
t_on_failure("1");
}
if (!t_relay()) {
sl_reply_error();
}
exit;
}
onreply_route[1] {
xlog("incoming reply\n");
if (has_body("application/sdp")) rtpproxy_answer();
exit;
}
onreply_route[2] {
xlog("incoming reply\n");
if (has_body("application/sdp")) rtpproxy_offer();
exit;
}
When starting OpenSIPS everything looks fine:

Re: [OpenSIPS-Users] RTPProxy + OpenSIPS 1.7 Integration
Hi Nick,
are you sure the public and private IPs are local to the machine where
you run rtpproxy ? as I see that rtpproxy complain on not being able to
use the ips you configured via the "-l" param.
Regards,
Bogdan

Re: [OpenSIPS-Users] RTPProxy + OpenSIPS 1.7 Integration
Hello Bogdan, Thank you so much for your response and time. I've been really struggling trying to get two way audio going. I think at some point I broke down in tears! This is a test virtual machine setup before migrating to the host servers. What I have is the following Router--->OpenSIPS/RTPProxy> Asterisk 1..n---> WAN ITSP Router 192.168.2.1 UC Polycom: 192.168.2.11 OpenSIPS: 192.168.2.102 Asterisk 1: 192.168.2.10 Asterisk 2: 192.168.2.11 My frist question is, do I need NAT and/or RTP Proxy since everything but the ITSP is on the same subnet? If not, I guess there is something wrong with my configuration. Eventually I will need NAT, and RTP, so I might as well try to get a grasp, and correct configuration using them. Can RTP proxy work when behind a router? Kind Regards, Nick. ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
Re: [OpenSIPS-Users] RTPProxy + OpenSIPS 1.7 Integration
After resolving the incorrect rtp proxy -l flag, i'm still having a
hard time getting two way audio behind a router.
What I have in my config is the following:
./rtpproxy -s udp:127.0.0.1:7789 -l 192.168.2.102 -m 1 -M 2 -u
root root -F -d INFO LOG_LOCAL0
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7789")
route{
if (is_method("INVITE") && has_totag())
engage_rtp_proxy("ie","192.168.2.102");
if (is_method("ACK") && has_body("application/sdp")) rtpproxy_answer();
}
route[1] {
if (is_method("INVITE")) {
xlog("Start Call for route [ fu=$fu/ tu=$tu /ru=$ru/ ci=$ci]");
if (has_body("application/sdp")) {
if (rtpproxy_offer("ie","192.168.2.102"))
t_on_reply("1");
else t_on_reply("2");
}
t_on_branch("2");
t_on_failure("1");
}
...
}
onreply_route[1] {
xlog("incoming reply\n");
if (has_body("application/sdp")) rtpproxy_answer();
exit;
}
onreply_route[2] {
xlog("incoming reply\n");
if (has_body("application/sdp")) rtpproxy_offer();
exit;
}
I do have two way audio once every 30-50 calls, but cannot pin any
combination that would keep things
working. Outgoing audio always works. I really appreciate any help on this.
Kind Regards,
Nick.
