Hi David,
Kamailio is a proxy, so it cannot endogenously originate either requests
or most replies. A 200 OK to an INVITE transaction can only come from a
user agent (endpoint), and Kamailio's sole job is to forward it. So, the
200 OK is going to come from the auto-answering callee.
To engage RTPEngine in both directions, you need to intercept the 200 OK
that is generated from the callee and call rtpengine_answer() /
rtpengine_manage() on it:
---
route {
...
if(is_method("INVITE")) {
...
rtpengine_offer("...");
t_on_reply("REPLY");
if(!t_relay())
sl_reply_error();
exit;
}
...
}
onreply_route[REPLY] {
if(is_method("INVITE") && sdp_content())
rtpengine_answer("...");
}

Hi all,
I'm building an automated load testing system for an rtp media server with TURN that
uses Kamailio for SIP.
When a client sends an INVITE to Kamailio, I need Kamailio to respond with "200
OK" and the SDP generated by rtpengine.
I've enabled auto-answer in the client, so as soon as it receives the response from
Kamailio it will start sending RTP packets.
Right now I'm usingĀ send_reply("200", "OK"); which is sending the
right 200 response back to the client, but it doesn't include any body.
How can I get Kamailio to send a "200 OK" and add theĀ rtpengine_answer into the
body?
Appreciate any help, I've been struggling with this for three days.
Cheers.
rtpengine_offer("SIP-source-address ICE=force-relay
RTP");send_reply("200", "OK");
