[Freeswitch-users] doublenat outgoing call issue

[Brian West]

Step 1. Revert everything back to SVN trunk.
Step 2. Enable UPNP/NATPMP on both routers.
Step 3. It should just work.  The doublenat profile is NO LONGER NEEDED.

If you can't enable UPNP/NATPMP then by all means static map the ports correctly or put the FreeSWITCH box in the DMZ on both ends.  It should just work.
