Because the drivers for the Dialogic cards are not open source, you have
to pay Digium for each phone line that will be in use. I think the cost
was $15, but I may be wrong. So for your 6 line install, you are looking
at the cost of the cards plus the cost of the license at $90 or so. 

None of us are pushing you to a channel bank because we will make money
on this. We are trying to help you out. If you go the channel bank
route, replacement parts are easier to come by and expansion is much
easier. It is a lot easier to justify an expenditure that has growth
ability at essentially the same cost as an option that has less.
