[quote=“zmanea”]One server should accomodate 40 users, depending on your environment. All 40 users are probably not going to be on the phone at the same time all day, but this could be the case for you. Are you going to have many meetme rooms?
I would suggest the following:
Processor: P4 3Ghz
Ram: 1 gig
Hard drive: 2 80 gig sata drives mirrored
Telephony card: Digium TE110P (assuming you are using PRIs)
Make sure to use good components in your box, don’t go cheap.[/quote]
I doubt that processor will cut it. I’d suggest the P4 830 (or better) or one of the Athlon 64 X2 chips. Multiple cores will only add about $100 to the system cost and you’ll really see the improvement with multiple calls.
As to the memory, I’d probably go with 2 GB to be safe. RAM is cheap so that won’t cost you but an extra $50-100. My estimates for building a box similar to that one (not including the Zaptel card) were less than $1000.
One thing to mention though, when building your own box, make sure you go with an Intel (for a P4 system) or nVidia (for an Athlon 64 system) chipset. Sis and Via are crap.
