[Freeswitch-users] RTP NAT No Audio on EC2

Fri Dec 19 01:17:59 MSK 2014

Thanks for responding. I've retested from another location and the calls
are now working as expected without any change so I presume it was an issue
with the device/network I was calling from. Sorry to waste your time but I
still struggle with a workflow for determining RTP issues. Does anyone have
any advice for a good article/book which would help? Cheers
