Hi

This might be due to the fact that EC2 uses SNAT  to map the private IP
address of the actual instance to the public IP address clients use to
connect.

To get around this you should use the "advertise" parameter to the listen
directives, like:

listen=tcp:<your private IP address>:5060 advertise  <hostname or public IP
address>:5060
listen=udp:<your private IP address>:5060 advertise  <hostname or public IP
address>:5060

So, if your ip address (as shown by ifconfig) is 10.212.129.99 and your
external floating address is 107.22.60.14 you would do

listen=tcp:10.212.129.99:5060 advertise 107.22.60.14:5060
listen=udp:10.212.129.99:5060 advertise 107.22.60.14:5060

Hope this helps.
