You'll do absolutely fine with this setup.  I have an office that has
about the same amount of phones and traffic as this (all using g711),
but probably with quite a bit more conferencing.  It runs on a Xeon
2.8ghz, 1GB Ram, 2 73 GB SCSI Raid 1.

I've been considering buying one of these, but don't have one yet.  If
anyone can comment, I'd like an answer, too.
