In my experience I don't see any benefit from dual cpu's on asterisk 
boxes unless you are doing a lot of transcoding and generally I would 
suggest trying to avoid transcoding as it generally works out more cost 
effective in the long run than continually adding hardware. I've found 
chan_sip to be a limiter long before the hardware is stressed.
