I think I couldn't explain myself clearly.
I want to see the following media lines in resulting SDP:
m=audio 10076 RTP/AVP 97 98
c=IN IP4 rtpproxy1.example.com
a=rtpmap:97 speex/8000
a=fmtp:97 vbr=on
a=rtpmap:98 telephone-event/8000
m=video 20007 RTP/AVP 96
c=IN IP4 rtpproxy2.example.com
a=rtpmap:96 VP8/90000

Do you want to change/update the SDP once the call is
established ?
shouldn't it just work like this:
if(has_totag() && is_method("INVITE")) {
if(search_body("video") {
set_rtpproxy_set("1");
unforce_rtpproxy();
set_rtpproxy_set("2");
offer_rtpproxy("$avp(myflags)");
}
}
Since it is already a ReINVITE any modification in the SDP c= part should
be happily accepted !?

Hi Sammy,
I'm not sure it will work.
Assume the following scenario:
Kamailio receives INVITE with audio only SDP and selects rtpproxy-1.
After a while video is enabled with REINVITE.
Now SDP has video and kamailio selects rtpproxy-2 according to your
solution.
In this case, most probably video and audio rtp packages will flow
through rtpproxy-2.
However what I want to do is to keep rtpproxy-1 for audio packages and
add rtpproxy-2 for video packages
and release audio ports from rtpproxy-1 and video ports from rtpproxy-2
when BYE received.
Is there any easy way to do that in Kamailio?

Hi,
Yes thats possible as I think you can do a search in SDP body for
"video" if found then select the rtpproxy instance else select other one.

Hi everybody,
Is there a way to use different rtpproxies for different media types?
I want to use one rtpproxy set for audio, and use another one for video.
Is this possible in kamailio?

Koray
