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,

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
