For instance:
Find your concurrent calls in the first column, and view your recommended system requirements.
Concurrent Calls | Processor | RAM | Hard Drives* |
< 5 | 500 Mhz | 256 MB | 40 GB |
5-10 | 1 Ghz | 512 MB | 80 GB |
11-24 | 2Ghz (Single or Dual Core) | 1 GB | 500GB – 1TB |
25-50 | Quad Core Xeon | 2 GB | 40 GB + NAS |
51-100 | 2 x Quad Core Xeon | 4 GB | 40 GB + NAS |
