[Freeswitch-users] How to get the network address of registered Endpoint (NAT Problem)

[Mitja]

Hey Steven,

actually that was one of the first things I tried. I also upgraded my FS 
to the newest stable and tried it without success.

BUT: Just to be save, I did the test again. And it worked as described. 
Maybe I had a typo or some.

Thank you for your time.

Once again the inbuilt greatness of FreeSWITCH prevails :)
