Help please... how many simultaneous calls can it handle?

How many simultaneous calls can asterisk handle? Does it depend on the server it resides? Can anyone give me some specification of the server for different simultaneous calls…

Check out Chapter 2 of the O’Reilly Asterisk book, particularly p. 12.
