Free PBX maximum call limitation

Posted on 2008-10-25
Last Modified: 2013-11-12
I can do with alittle advice.

I'm building a system to ultimately handle 1000 simultanoues calls and have the option of using a simple Asterisk installation with A2 Billing or the full package e.g. Free PBX or PBX in A Flash Distro's. Can you see any call limitations in using the Distro's ?

My concern is the extra overhead they place on the server. However they make ones life simpler and also provide for graphical monitoring tools.

Any real life solutions welcome and comments.

The only theoretical maximum is based on server hardware limitations, network switching/routing hardware limitations, and internal/external bandwidth....

Other than that...multiple Asterisk servers can be clustered to support any number of calls much greater than 1000.  This adds complexity to the setup however.

I only use Cent i'm not the best person to attest to the stability of other distro's like Ubuntu or Red Hat...

The reason I use CentOS..... when I took my Asterisk lab course...every machine was using CentoOS....I asked the instructor why, he said it was the most stable for Asterisk, in "HIS" opinion....  so I went with that and been using it ever since in production...

I can't see why it would be an issue....
Like I said's limited only by what the hardware is capable of.
