Anthony,
If the only thing you want to do, is NAT traversal, then that's been done
before. Have a look at http://onsip.org/ The Getting Started document and
config files explains how to do NAT traversal with rtpproxy and mediaproxy.

Subject: [Serusers] Rewriting SDP Infos for NAT Traversal
Hi,
When an INVITE request is incoming, I need to rewrite VIA Header Field,
Contact Header Field, (c=) field in SDP message core and (o=) field in SDP
message core too with IP public adress of UAC. Those are needed by my SIP
Server before SER Proxy forward the request to him.
I got some success with rewriting Contact Header File by using
fix_nated_contact() function and (c=) field with fix_nated_sdp("1")
function. But I don't succeed at all in rewriting (o=) field and partially
for VIA Header Field.
To do so, I tried to use the following function :
fix_nated_sdp("8"); No Result :(
forcerport(); It seems to add real IP public adress and
port in VIA header field but it's not
rewriting IP private adress
So, finally is it the good way to do this thing or is there something
wrong with my behaviour ?
Thanks,
