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, De : Daniel-Constantin Mierla [mailto:mico...@gmail.com] Envoyé : jeudi 27 juillet 2017 11:41 À : Kamailio (SER) - Users Mailing List <sr-users@lists.kamailio.org>; Nicolas Breuer <nicolas.bre...@belcenter.biz> Objet : Re: [SR-Users] Add SDP Body Hello, On 27.07.17 09:57, Nicolas Breuer wrote: 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)?
