Darren,

channels, I either have to use this kind of setup or an analog adapter? 
It's good to know that this setup will indeed work.  However, I don't think 
that I'm going to get approval to purchase a $3,000 fax card and a $1,500 T1 
card.

So I guess I'm stuck with the analog adapters....

Thanks for your help.
