[asterisk-users] Best config for 12 FXO system?

[Mojo with Horan & Company, LLC]

Those are all analog though, aren't they? What about a channel bank into 
a digital card?  Might that be cheaper than shelling out for 12 FXO 
ports and the cards to hold them? 

Just wanted to throw that out there before the discussion started :)
