Hi- I've run extensive load testing with both single and dual P4's and Xeon's (all at least 2.8GHz), and I've got 6 installed IVR systems of this size in various configurations.
Asterisk can run 4 E1's (120 channels) in an IVR scenario, but just barely. With this many simultaneous calls, you may notice a bunch of frame retransmissions in the error logs, but these don’t seem to effect the calls. There seems to be lots of call setup overhead, because I notice that shorter calls (<5 seconds) seem to load the processor more heavily. For IVR only, I don’t think its necessary to use the Xeon, or really dual processors for that matter - unless you're going to start doing transcoding or other processor-loading tasks. Please see my notes on the Wiki on this topic: http://www.voip-info.org/wiki-Asterisk+dimensioning Regards, Scott Stingel Scott M. Stingel President, Emerging Voice Technology, Inc.
