did you do all the things in https://wiki.freeswitch.org/wiki/Amazon_EC2
Also are you using the external or internal profile (port 5065 is the

if you want to use internal you have to comment out the auth-calls and the
inbound acl lines.
Most of this should be available in our various books and wiki articles.
