Hi,

There is a `write_sdp_pv` parameter in the rtpengine module that makes
rtpengine return the new SDP in a variable rather than in the message
body. Personally I find it's more convenient to transform a variable
several times than working directly on the message buffer and applying
msg_apply_changes() several times.
