<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:FR-BE">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.<br>
<br>
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)?<br>
<br>
Cheers,<br>
