<tt>Hi, Jeff!<br>
<br>
Unfortunately you can't use both rtpengine and codec_delete_*,
that's because each change different buffers. The codec_delete_*
function runs on the initial SDP received, then rtpengine
completely overwrites the SDP with whatever rtpengine replied.<br>
The only way you can do something like this (although it may be
very ugly) is to store the rtpengine reply in a pvar using the
3rd[1] parameter of the rtpengine_* functions and perform some
text replaces[2] on it, then replace the body "manually".<br>
