The difference is due to the fact that rtpengine rewrites and replaces 
the entire SDP body, while rtpproxy only manipulates bits and pieces of 
it (like ports and IP addresses). Since Kamailio doesn't perform SDP 
changes immediately but rather collects them in a lump list and applies 
them only when requested (or when the message is sent out), trying to 
apply two rewrite operations on the same SDP portion doesn't work.
