I don't know what the remote carrier is using for
their RTP. I set a custom nortpproxy_str to try and
avoid this (instead of leaving it as the default
a=nortpproxy:yes). Is it correct for them to leave
our custom a=schipmangled:yes record in the SDP? I
have had problems with the "f" flag and failover
routing (basically rewrites the IP in the SDP twice
like this yyy.yyy.yyy.yyyyyy.yyy.yyy.yyy). Is there
an easy way for me to just remove the
a=schipmangle:yes in my onreply_route?<br>
<br>
Thanks,<br>

I am having a problem with RTPProxy where in
the reply, the remote carrier is sending the
"nortpproxy_str" in the reply SDP (example
below). I would like to know what the best
way is to detect this, and remove it from the
sip message before calling rtpproxy_answer
function, because rtpproxy_answer will fail if
the nortpproxy_str already exists in the SDP.<br>
<br>
Thanks in advance,<br>
