I was thinking of building a small asterisk machine for a non-profit. I was reading the hardware requirements, and the site lists a pentium 4 3ghz with 512 megs ram on a 20 gig HD for an office that runs 60 did numbers, with 100 phones in two offices to handle all the call routing.
I want to run 10 phones, will a dual core 1.8 atom processor be enough to run it? http://www.newegg.com/Product/Product.aspx?Item=N82E16813138299
is what I had in mind. A small SSD, 4gb of ram, the 64 bit version of Asterisk. End phones will most likely be cisco 5108G.
