[Freeswitch-users] RTP NAT No Audio on EC2

Fri Dec 19 12:40:22 MSK 2014

Hello Luke - didn't expect you to pop up - hope all is going well for you!
Merry Xmas

Cool thanks guys, i'll have a read. I do have a general understanding of
NAT but i'm not able to recognise whether an issue is due to my box
configuration or something natty just from looking at a trace - maybe i'm
hoping for too much! You know, if my wireshark trace is showing RTP being
initialised to a remote internal IP i'm assuming that means its not
correct... Maybe its a case of Jack of all trades!
