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. 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 But the port is not correct (no changes) ..

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)?
