Problem with outgoing calls on AWS EC2 instance

I have installed FreePBX on an AWS EC2 instance and have not been able to make outgoing calls.

I am using a Zoiper softphone. It registers okay using the Elastic IP I have associated with this instance.

I am able to place calls to extensions using the Softphone but if I try to dial a call using my trunk, it fails. I see messages that refer to joining “simple_bridge” and I have a feeling that this may be the problem.

Any ideas on how to debug or any configuration changes I might make?

I believe the call is being established but I cannot hear anything.

The CDR is showing that the call was answered so the problem is that I cannot hear anything

One-way audio, even when it’s both ways, is almost always a problem with NAT settings.

In this case, since you’re on AWS, it’s possible that you are not passing the correct RTP ports from the AWS firewall to the server. More information would yield better guesses.

It turned out that my account was blocked for too many failed authentications. Problem has been solved
