AFAIK (there's that acronym again :):) ), the Dell issues were related to interrupt sharing and multiple PSTN interface cards. You mention below SIP/SIP only, so I wouldn't worry. The HP should be fine. > > As for CPU, the question is mostly one about more GHz or more cores? Dual > cores are cheaper by GHz. What`s best for Asterisk? That's actually a decent question. Anyone have any benchmarks? It is the transcoding that will eat your CPU. I think with minimal transcoding you would have a hard time overloading a 2.4GHz machine before other factors came into play. > > I am doing only SIP to SIP calls.

If you want a redundant setup, run multiple smaller cheaper machines with a load balancing front end.
