Asterisk Server Sizing Tool

Does anybody have or know where you can get a detailed server sizing tool for Asterisk that would give the required CPU, RAM and Storage?

This would need to take into call volume (in/out), end users, SIP/PSTN trunks and use of other applications (i.e. Voice mail)

Thank you.

Because of the constantly evolving nature of Asterisk as well as the nearly infinite possibilities for its use, no such tool exists.
