[VoiceOps] question about campus installations

[Shripal Daphtary]

Hey all, i have a question that i could use some help on.

I have a customer that wants to replace a PBX that is shared between
administration and residences in a campus environment with a VoIP solution.
 PBX currently has a digital phone in each residence connected via
CAT3/rj11 back to a RJ21x the MDF.  There are 238 units.  customer would
like to provide POTs service to each residence with some class 5 features,
VM, CLID, 3WAY, etc. There is not Cat5/rj45 connections in any of the units.

I was thinking of bringing in several Adit600 chassis, with 5x8port FXS
cards in each, which would give me 40 FXS ports/chassis.  meaning  6
chassis.  i would likely use MGCP, b/c it works well with the Adit.

I can't seem to find a better/larger device that does more than 40 FXS
ports, besides a PBX.  does anyone know of a product/channel bank that can
handle more?  i can do SIP or MGCP.

oh, i know that i can get a CAT 6500 and populate it with a couple CMMs and
populate the CMMs with 24 port FXS cards (WS-SVC-CMM-24FXS), but the client
can't maintain it.


I'm running an Broadsoft M6.

thanks!
