[asterisk-users] Need Reference sites

[Michael Davidson]

Hi,
    I'am comparative newbie to the world of Asterisk. I'd like to 
introduce an Asterisk based PBX into my company but need to convince my 
executive of it's worthiness. I need some reference sites to quote in my 
discussion, preferably well known companies of course. I have surfed the 
net but not come up with anything of note, if anyone can help it would 
be greatly appreciated.

Thanks, Mike D.
