FreePBX estimated configuration

Good morning,

I’m looking for a PBX to handle ~300 concurrent calls and maybe 50 calls per second, I’m already using FreePBX with smaller customers (~10 CC) but I’m not quite sure about the machine sizing (it will be on AWS).

Is there someone that have/had a similar experience? Or maybe is there a way to calculate what I need? The functionalities will be very basics: no call recordings, (preferably) G711 and a very simple CLI translation rule.

Also I’m not quite sure how to test this since we don’t have 300 numbers to dial…

Thank you in advance to everyone that will help!

Simple, setup a second FreePBX system and setup 300 trunks between the 2 systems.

I’m sure you can get some ideas on scripting this from here:
