Hello Again,
I found a way to engage.
I added in the code
append_hf("Content-Type: application/sdp\r\n");
before set_body
I can now see the proxy is engaged
v=0.
o=XX 10 10 IN IP4 217.112.180.9.
s=XX.

a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-15.
a=sendrecv.
a=ptime:20.
a=nortpproxy:yes
But the port is not correct (no changes) ..

Hello,
there is a dedicated function to set the body, do not use append_hf(), because
kamailio doesn't detect there is a change of the body and content length is 0.
Cheers,
Daniel

Seems that proxy was not engaged. -> The port is not altered..

Hello,
I'm trying to add a SDP Body on 183 replies.
>From some carriers I don't get any SDP.
The goal is to add SDP , Engage PROXY & stream2uac on all 183 packets without
SDP
Do you think it's possible ? :)
it may be possible, if you try to combine adding content-type header and the
sdp body, then use msg_apply_changes() inside reply_route{}. Later engage the
rtpproxy. However, if you don't know the codecs of caller/callee, it may end in
a mismatch.
Just dropping such 183 is not ok? If not, what about turning 183 in an 180? Or
setting an SDP with media IP 0.0.0.0 (old on hold style)?
Cheers,
Daniel
