[Bruce Reeves]

Brandon

Your on the right track with what is can do. It will also be good to
look into what kind of QOS you can do on the T-1 connections between
offices. I have an 8 office setup similar to this and many of your
goals I have achieved and would be glad to offer ideas and such if you
want to email me off list.
