NAT ISSUE

michel freiha
Dear All,

I have the following issue...When I try to make a call from a Softphone behind a NAT, the IP address that appears in the SDP header of the INVITE message is the private IP of the Softphone instead of its public IP...I know that I should force rtp proxy in INVITE and onreply route and already did that but it seems that i sill face the same issue...

Kindly find my Opensips.cfg file on http://pastebin.com/d43aec87c....

Please let me know if I'm missing something

Regards

I think nobody will check a full opensips.cfg file (al least not me).
I suggest you to capture the SIP flow (using ngrep for example) and
check if the SDP's are modified. By doing so, you will realize of
which SDP is not modified and the issue will be easier to fix.

Try using the nat_traversal module, it helped me.
