Norstar, at least some models, apparently supports something called T1/E1 QSIQ which allows for EUM integration. Most people since the release of OCS 2007 R2 are using SIP trunking.
Sorry. Exchange UM is no longer my area of expertise. :( (I used to be a Unity expert, long ago and far away.) The Exchange upgrade path is certainly doable and can be planned for UM/OCS at later date. That I can say with certainty. Regards, Michael B.

That helps put things into the appropriate boxes, which is unfortunately the rudimentary knowledge level at which I find myself right now. I've uncovered innumerable references to Dialogics and Audiocodes media gateways, but I didn't know how to interpret the results. Our (very old, but going strong) Norstar system may, or may not, have a compatible gateway product that would allow us to leverage it -juuuuust a little bit longer-... (Boy, would it be nice if one exists...) My ideal upgrade path for our ~100 user environment (subject to much amendment / correction / improvement) is to migrate from on-premise Exchange 2003 (single server) to on-premise Exchange 2010 Standard with Enterprise CALs on Server 2008 R2 Enterprise (two servers with fully redundant roles). Server Enterprise would be deployed to take advantage of mailbox resiliency, and Enteprise CALs to immediately utilize archiving, custom retention, and delegated multi-mailbox search. Down the line I would like to add UM, but that is almost certainly a phase 2 project because of the likely cost involved in ripping out and replacing the Norstar. If a Norstar-compatible gateway happens to exist, that might allow us to add UM on the front end. As always, comments, and corrections (and even the occasional humiliation) are always appreciated.

I'd have to hunt it down, but there is a certified gateway partner listing somewhere on Microsoft.com. In general, anything that talks TCP SIP should work. Exchange UM is more-or-less equivalent in concept to Unity - that is, Unified Messaging (Unity and its various add-ons are far more mature in feature set - but the average business user wouldn't notice). OCS 2007 R2 is more-or-less equivalent in concept to CallManager - that is, a software-based PBX. In terms of PBX functionality, CallManager wins, hands-down. In terms of other functionality - IM, presence, Office integration, whiteboarding, screen sharing; OCS 2007 R2 wins, hands-down. Regards, Michael B.

I haven't been able to find any good/definitive resources. To the original poster, does this question mean that you are looking at replacing Unity with OCS 2007 R2? Please forgive me if that's a ridiculous question. I'm coming to the whole UC/UM arena from a place of complete ignorance.

In Unity you can assign multiple extensions to a single mailbox. Is this possible with Exchange UM? I have not found anywhere to indicate a extra number location. Thanks
