I’ve looked on various sites and can’t find a definitive answer or the answers I can find are at least 5 years old.

Is there a place where I can find the hardware requirements for an asterisk machine? A site where I can punch in my requirements and it makes a suggestion?

I have 100 ddi’s
1 have 150 internal extensions.
Don’t expect to receive more than 30 concurrent calls.
Am a heavy user of conference calls.
Would like to use voicemail to email.

I’m sorry to ask but the hardware is what is causing me to scratch my head rather than the configuration.


There is no exact formula for selecting the correct hardware. But according to you spec, almost any mid-range server will do the job with ease.
