[Freeswitch-users] Extension: No audio

Hi! I have FS natted and am connecting with an 'external' extension that is registered to FS. ie the extension 2000 is registered on the internet with a public IP through my router to FS (192.168.1.120 IP address). uPnP works and I see that the extension is registered successfully. The problem is that I do not get any audio When looking at the SIP trace, I see the INVITE but do not see a TRYING or RINGING message. The extension is actually ringing. I modified the RTP port range on the remote end to match the RTP ports of freeswitch. I have put a sip trace in the pastebin at http://pastebin.freeswitch.org/11035 If anyone has an idea what needs to be set to get audio, help appreciated. Thanks!
