In my experience of having certain functions like that I clearly favor using
dedicated h/w. It allows you to do things with your normal machine without
interrupting your communications (phones and the like).

It's like having a dedicated firewall. Does not matter what I do internally,
it's still there doing its job. Of course I do have a few machines around so
it's not so hard. Still, any old machine will usually do for SOHO type
setups. I've run Asterisk on a 200MHz machine and 20G drive. (Just stay the
hell away from USB TELCO devices. They are nothing short of wast of time.)
