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>
