That's kind of a chicken-egg problem. If BRI isn't advertised/offered/encouraged, then who's going to buy the right cards? As for the cost: in the example I provided, the difference is barely there -- if I get two calling features for each line, I'm better off with BRI on a one year contract. (Of course, I haven't taken into account analog bundle pricing, which would bring the cost for features on analog lines down some. But again, I don't see the difference being very big. It all ends up concentrating on the same telco equipment anyway.) > With fiber being deployed to most buildings (or at least RTs) nowadays, > the line cards do not play a factor since the DLC has to already be > there.

Most businesses are using relatively modern PBXs now, so -- provided the appropriate module is installed in the system -- you should be able to run the BRI right to the customer premises. The other stuff you describe just sounds like a way of getting more line density out of older infrastructure. -Stephen- _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
