Hello,
Yeah, I also noticed I forgot the / . Now the SDP c parameter is set correctly,
but the audio from private to public isn’t relayed by rtpproxy.
I ran a tcp dump on both interfaces (private and public), and it showed me RTP
is being received from Freeswitch and also from our carrier, but nothing is
passed between the two interfaces by rtpproxy. Any ideas?
Below a slim version of my config:
Request_route {
if (is_method("INVITE")) {
record_route();
if (has_body("application/sdp")) {
rtpproxy_offer("ei");
}
}
}
onreply_route[MANAGE_REPLY] {
if (has_body("application/sdp")) {
rtpproxy_answer("ie");
}
}
route[WITHINDLG] {
if (!has_totag()) return;
if (loose_route()) {
if(is_method("BYE")) {
rtpproxy_manage();
}
route(RELAY);
exit;
}
}

Hi,
Try starting rtpprpxy with a / in between the two IP addresses.
For example -l 1.1.1.1/2.2.2.2<http://1.1.1.1/2.2.2.2>
Besides that it depends where you are placing your rtpproxy function.
BR,
Sammy

Hello,
I’m using RTPproxy for the first time in bridged mode and I can’t get
kamailio/rtpproxy to rewrite the c parameter to the correct public ip address
of kamailio.
The setup is as following:
Carrier ------[fiber]------ Kamailio ---------[lan]--------- Freeswitch
Kamailio is listening on two interfaces:
1) Private: 172.0.0.1
2) Public: 192.168.0.1 (since we have a dedicated fiber with our carrier,
this is its public address)
Freeswitch is listening on:
1) 172.0.0.2
Carrier is on:
1) 10.0.0.1
I’ve started an rtpproxy instance on the Kamailio box using:
rtpproxy -s udp:127.0.0.1:7721<http://127.0.0.1:7721> -u rtpproxy rtpproxy -p
/var/run/rtpproxy/rtpproxy.pid -l 192.168.0.1 172.0.0.1
I’ve played around with rtpproxy_manage() and the various flags (ie, ei), but I
can’t get kamailio to set the correct public IP when the 200 OK has to be sent
back to the carrier.
It always sets it to its private address, instead of its public address.
I’m using Kamailio 4.2 with sippy/rtpproxy 2.0.
Could someone please point me into the right direction?
Thanks!
Grant
