asterisk users - Jul 2005 - Referrals/Success Stories would be greatly appreciated

Hello,

    I am looking to replace my company's Avaya Merlin Magix system with 
an Asterisk based PBX when our current lease is up.  I had a meeting 
with upper management yesterday, and they would like some assurance that 
other companies are running Asterisk with success.  We are a relatively 
small company, with about 70 total extensions.  I would be purchasing a 
Dell Poweredge 2850 Server and most likely a Sangoma A101U.  The phone 
service would be provided by a ISDN PRI from SBC, with Caller ID and 
DID.  The phones we are looking at are the Uniden UIP-200, and the Cisco 
7940G on the high end.  I've become fairly familiar with Asterisk, and 
i'm pretty confident that I should be able to squash most of the 
problems that come up with the help of Google.  If anyone would be so 
kind as to post success stories, or even potential problems we should 
look out for, I would greatly appreciate it.

Thank you,
