<br><br>Callee is firewalled, but not NAT. callee is on the same subnet as the asterisk box. Asterisk box has been completely excluded from the firewall rules, and all traffic is being passed to it. Provider says everything is good on their end.
<br><br>Incoming calls work fine.<br><br>Here is the config from sip.conf for the provider:<br><br><br><br>[general]<br>context=incoming<br>srvlookup=yes<br>canreinvite=no<br>videosupport=yes<br>qualify=yes<br><br>; trunk links
