[Asterisk-Users] Pitching Asterisk

[Sean Cook]

The company I work for is looking at vendors for a PBX, one of the
requirements is VoIP.  I have been sitting there listening to people
pitch very proprietary implementations of VoIP where you are locked in
to their hardware, their interface...

I know a little bit about asterisk (set up a couple offices with it...
run it at home...) and would like to pitch it to this company.  Does
someone have a decent presentation that I could use as a starting point?
Basically I am looking for a "business" oriented (not too technical)
overview of asterisk, or "asterisk for suits".  

any help would be appreciated.
