PIAF not able do 500 concurrent calls on EC2 on any node.

For example on c1.medium will be 50-80 calls.

500 concurrent call task is not task for asterisk. You should use kamailio/opensips or scale to multiple asterisk boxes.

Extension2extensions calling also have use some protocol(usually sip).

Considering question you asked very likly you need outsource project to team with asterisk experience.

    500 calls is setup for hi-perfomance hardware server, even on that it can be not reachable(will greatly depend of dialplan and optimization). On ec2 no way run it. – arheops Jun 04 '16 at 04:48
  • Appreciate your concerns. What about any other server like dedicated or google cowed servers. I am running 250 concurrent calls on Pinless application over SIP Trunk. Here in my application using pjsip based library, csipsimple android, siphone iOS. Extension to extension calling only. – Dhananjay Kashyap Jun 06 '16 at 08:44

    Question like "how much power need to get 500 calls" have no any sence. It will GREATLY depend of dialplan and module usage. 500 calls should not be placed on one server (any hardware) if you have such questions. – arheops Jun 06 '16 at 12:40
