hi all...fresh install of Unity 7.x. Wondering if we should install as a Unified Environment or Voice-Mail only? Our setup is that we have Exchange 2007 in-house. Our in-house users will have voice mail pushed to Outlook via Exchange. In the future, we will have hosted VoIP customers in our CUCM and Unity environments. The customers will never be part of our Exchange box, they will have their own.
Also, will another instance of Exchange need to be loaded on the Unity server to achieve this scenario?
Thanks in advance.
Putting aside the questions of scalability/security/etc. for the moment, it
is possible to have a UM experience for your internal users and a VM-only
experience for the external/hosted users on a single Unity solution. While
the hosted users won't have access to your Exchange servers from an Outlook
client (for example) the mailboxes will still need to be stored in Exchange.
You can have separate message stores (Unity can handle that). You will need
an AD account for each hosted mailbox (though the account can be disabled in
AD if needed).
I would recommend a separate message store and I would also recommend that
Exchange is NOT loaded on the Unity servers. Given that this will be a
hosted service at some point, it makes sense that you provide some level of
assurance with respect to fault tolerance. Which implies at least two Unity
servers. Having the Exchange service off box increases scalability options.
Cisco has switched stance on whether Exchange can be co-res with Unity or
not. I believe the latest I heard was you could, but scalability is a
consideration. A search on CCO would clear that up....maybe.
One additional thought. Depending on how expansive your hosted solution is
going to be, you may want to consider Unity Connection. It has the ability
to cleanly segregate multiple tenants on the same system. Meaning, it can
be configured as a true multi-tenant solution whereas Unity cannot (though,
you may be able to establish a perception of separation).
Unity Connection does not have true Unified Messaging today, but rumor is
that 8.5 will address this. Just a rumor at this point. Until then Unity
Connection can provide integrated messaging, which is "close" but opinions
