[Freeswitch-users] FS behind NAT encounter no audio

[Jimmy Chang]

Hi ,
I've added <action application="set" 
data="disable_rtp_auto_adjust=true"/> to my dialplan, but not worked.
I need to explain the architecture of our environment.
We have a IVVR server.
FS, IVVR server and agents are all in the same LAN. The clients are in 
the internet.
Here is the scenario.
1) A client makes call to FS.
2) FS bridges to a IVVR server for playing ivvr.
3) IVVR server bridges the call back to FS queue.
4) Available agent pickups the call.

I know it may be NAT setting problems, and I've tried to create a new 
profile(template from external) for the ivvr gateway.
Now the client can hear the agent, but the agent can't hear client.

Any advice?
Thanks.
Jimmy
