We were migrating from a Toshiba digital system to VoIP in phases. I
had 4 PRIs between the systems and 5 PRIs to the phone company. It's
running on a Dell R710 with two Intel E5520 quad cores and 6GB of
memory. The hardware is probably overkill, but dual processors are
cheap compared to PRI cards. During the middle of the day we average
50-60 concurrent calls with around 4,000 calls per day. System load
stays right around 1.00.
