One thing to keep in mind when dealing with Cisco 3600 routers (and
others with ALG functionality) is that if you are using mediaproxy or
rtpproxy and accidentially call use_media_session() or
force_rtp_session() more than once when dealing with NATed clients,
that SER will corrupt the c= field in the SDP payload and the Cisco
3600 will refuse to pass that message -- we can call this a "feature"
:-)<br>
