<font face="monospace">Hi Wadii,<br>
<br>
I haven;t checked the implementation, but the rtpproxy_engage
should take care of the 183 with SDP. Have you tested it?<br>
<br>
Regards,<br>

hello , i do have a question related to rtpproxy module
documentation.<br>
<br>
The doc describes that rewriting sdp body should happen during
either INVITE , 200 OK or ACK.<br>
In the case of SDP presence on invite <=> 200 , one should
rtpproxy_offer during the invite and rtpproxy_answer during the
200 OK.<br>

I think those sdp packets should also be rewritten with the
right rtp proxy ip/port. In which case the doc should mention
"SDPs are in INVITE and 200 OK /183 Session Progress".<br>
<br>
My second question : since we can handle most cases with
rtpproxy_offer/answer methods, what is the purpose of
rtpproxy_engage ? is it to ease the management i described above
? <br>
<br>
Thank you<br>
