First off I think you would have a rough time making one server handle so 
many calls.  It also depends heavily on whether or not you will be 
transcoding those calls.  Regardless you should split the load for the 
simple reason that such a high density service would be in absolute 
tatters if your single point of failure failed for any reason.
