Asterisk doesn't use very much RAM itself, but any swapping could
destroy call quality. My 2 main asterisk machines that are in production
only have 256 megs and perform just fine. All newer machines are getting
512meg or more but it is mainly because of the cost is negligible to do
the upgrade now.
