Hi Mike (and everyone else!),
We've got some experience in this area as well. In addition to some
smaller accounts, we've provided consulting and deployment to a couple
large companies that are evaluating or actively deploying Exchange UM
to their employees. They run the gamut as far as location and
industry but range in scale from 2000 users of Exchange UM currently
deployed and more planned, 11,000+ currently deployed with end-state
at 25,000+ and a deployed pilot with end-state of over 100k users
internationally.
The larger companies that we deal with are certainly very active in
planning now for Exchange UM and many are picking up the pace for OCS
as well, so I'd say there is certainly precedence for the 10k users
you're talking about.
I think one of the key things that has resonated with our customers
and prospects is how they can have aging, disparate PBXs yet provide a
consistent messaging platform for their users. This allows them to
phase out older call control systems over time, over years, yet have a
consistent UM solution. Saves money, time and training dollars.
Hopefully that helps.
