Depends on what you are doing with those channels. Are you recording calls, Transcoding calls, Playing IVR, Conferencing calls, Dialing SIP Endpoints …? There’s no simple answer to your question!
Best way is to use a tool like sipp to generate calls for Asterisk and check the load on the server and Asterisk CLI for any possible warnings and errors.
Personally even when using sipp, I would have some human making real calls in Asterisk to check the audio quality.
P.S. Note that there’s a difference between CPS and Concurrent calls in Asterisk. However sipp can help you test both the cases.
Hi thank you for your answer.
We are working as transit carrier and using asterisk as mediaserver to reduce latency. So we just passing call to another endpoint.
Hmm so there is no way to figure it out without testing ?
No. Asterisk is just a toolkit and load depends on what you are building on top of Asterisk.
There is no magic formula, only actual testing.
Okay thank you for answer guys, I understood! Apprecaite!
