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)?

Hello Daniel,
I added this
if (status=~"[1][8][0-3]"){ setflag(22); if (is_method("INVITE")) { xlog("L_NOTICE", " No SDP"); append_hf("Content-Type: application/sdp\r\n"); append_hf("\r\n"); append_hf("v=0\r\n"); append_hf("o=XX 10 10 IN IP4 217.112.180.9\r\n"); append_hf("s=XX \r\n"); append_hf("c=IN IP4 217.121.180.9\r\n"); append_hf("t=0 0\r\n"); append_hf("m=audio 0 RTP/AVP 8 101\r\n"); append_hf("a=rtpmap:8 PCMA/8000\r\n"); append_hf("a=rtpmap:101 telephone-event/8000\r\n"); append_hf("a=fmtp:101 0-15\r\n"); append_hf("a=sendrecv\r\n"); append_hf("a=ptime:20\r\n"); msg_apply_changes();
rtpproxy_manage("corbf");
#rtpproxy_stream2uac("/root/wait.wav", "-1");
}
Seems that proxy was not engaged. -> The port is not altered.. Trace :

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.

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. c=IN IP4 217.112.180.9. t=0 0. m=audio 0 RTP/AVP 8 101. a=rtpmap:8 PCMA/8000. a=rtpmap:101 telephone-event/8000. a=fmtp:101 0-15. a=sendrecv. a=ptime:20. a=nortpproxy:yes

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

Hello Daniel,
I can now modify the SDP but streaming the ringback tone seems not to work. Where can I put the prompt ? I didn't find the prompt directory of the rtpproxy on my server.
I also tried the "old" fashion. Allow: INVITE,ACK,CANCEL,BYE,REGISTER,REFER,INFO,SUBSCRIBE,NOTIFY,PRACK,UPDATE,OPTIONS,MESSAGE,PUBLISH. Content-Length: 182. Content-Type: application/sdp. Content-Type: Content-Type: application/sdp. Server: Belcenter SIP Voice Gateway. . v=0. o=XX 0 0 IN IP4 0.0.0.0. s=XX. c=IN IP4 0.0.0.0. t=0 0. m=audio 0 RTP/AVP 8 101. a=rtpmap:8 PCMA/8000. a=rtpmap:101 telephone-event/8000. a=fmtp:101 0-15. a=sendrecv. a=ptime:20
No ring back tone for the callee
If you have any ideas,

I'm trying to add a SDP Body on 183 replies.
From some carriers I don't get any SDP.
