Maybe the message gets looped to your openser before rewriting the SDP?
Watch the loopback device for looped messages:
ngrep -d any port 5060

I call fix_nated_sdp()

t_on_failure("1");

I'm using openser 1.1.0 notls, on a dual opteron server running CentOS 4.3
here is a trace of the code in action.. (names changed.. because I enjoy
search and replace)

As you can see, the code is appending 127.0.0.1 for no good reason (at
least that I can tell)
Any ideas (bug fixes, or tricks...)?
