[Freeswitch-users] FS behind NAT encounter no audio

[Jimmy Chang]

Yes, problem was the firewall of the softphone pc.

I also found another problem.
When I used linphone for the softphone client, the agent could't hear 
voice from linphone.
I have set "Direct connection to the Internet" of the linphone but still 
got the one way audio.

Thank you all.
