Where I can find hardware requirements list for 20 users size company ?
a Pentium 4 an up with 512 of ram would be more than good. Are you going to connect to the PSTN? How are you going to do this? fxo lines?
I've found the issue is less with the number of attached staff, and more with the volume of concurrent calls, and transcoding between codecs.
Basically if you've got 256MB RAM and can install Elastix, it'll probably suffice a few SIP calls.
If you were going to prepare for a 1:1 ratio, try and aim for around 60-70Mhz per-concurrent call, so 20 * 60 = 1.2Ghz. It's broad and generic and some calls require more CPU time than others when transcoding, same for MoH etc, but as a rough rule-of-thumb it'll give you a good idea
Yes, we are connecting to PSTN with FXO.
P.S. How about 50 users with same environment ?
