Hi all, I have a ser(0.9.4/Freebsd) server well working, but in some cases, I have a strang behavior. I use rtpproxy for nat traversal,all my users can call pstn, but when we try to call one of our users from internal or from pstn, Ser sends many invites and callee never answer to these invite. I must conclude that they don't receive it... All the users having that problems are under a nated network. Any idea ? Olivier
