How will you connect your site with your customer's site?  A data-only 
point-to-point T-1?  Or a channelized T-1?  At the customer site will 
you have a CSU/DSU and router terminating the T-1?  SIP phones on the LAN?

Some of my clients are not very computer savvy (Win98).  When I 
suggested web, mail, and file servers for their operation, they replied 
"what's that".  Now they couldn't be without their file server (Samba), 
they've brought their web server in house (Apache), and they have their 
own mail using their domain name (qmail).  They love it.

While I can see Asterisk centrex services (al la ICG), I prefer 
providing a complete IT solution for their needs.  I can manage the 
boxes from afar, and the clients are happy.
