› VitalPBX Community Support › General Discussion › VitalPBX on AWS EC2 – NO AUDIO
I’ve just installed VitalPBX on AWS EC2. I’ve set up Security Group as shown here, also I have an AWS Elastic IP, which points statically to my instance.
I can connect my Extensions, correctly set-up Time Conditions, Ring Groups and Announcements, I only have a problem: audio.
To recap: I have a Static Public IP for my Instance which is located at Frankfurt, and my phones are in my Home Network, so two different places.
When I try to call an external number (my mobile phone), the call lasts 5-10 seconds and then it fails. I’ve also set up codecs supported by VoIP providers. I believe that this is a NAT problem.
In every part of the system (Trunks, Extensions) NAT is set to Default.
In Settings > SIP Settings, NAT is set to Force, Comedia and External Address is set to the AWS Elastic IP.
Can anyone help me? I don’t have any other idea.
Thanks a lot.
You may install the sngrep tool in order to get a full call trace for determinating what is happening, is an error with the tunk configuration.
yum install sngrep -y
