Mix and Match VMO and Unified Design Question

All,

We're currently looking at two vendors to replace our current voicemail system. Cisco Unity is one of the two products we're looking at.

Immediately, we're looking to replace voicemail for 3000 users in our home office. However, we'll be replacing the voicemail systems of our other offices as their current voicemail systems come off lease.

Currently, all offices receive their email from Exchange servers located in the home office.

What we're looking to do is provide voicemail only capabilities for 2800 users and unified messaging for another 200. We may, as time progresses, move more users over to unified.

From a design standpoint, from what I understand, we can:

1. Implement a single Unity server for unified messaging and implement another Unity server for the voicemail only users.

2. Implement a single Unity server. For those that are unified, point their Unity accounts to their primary Exchange inbox. For those users that are voicemail only, we can create an additional 2800 Exchange inboxes that the users cannot access through Outlook.

3. Go unified for all users.

Other than going unified for all users, our Active Directory and Exchange administrators are not excited about options #1 and #2. #1 seems like it'd be pain to manage as we would need additional servers, like a second Unity server, additional domain controllers, etc. #2 would require additional Exchange servers and it seems like it'd also be a pain to manage.

Am I missing something here? Are options #1 and #2 really our only options outside of going unified for all users?

Please let me know what you think. Thanks.

Re: Mix and Match VMO and Unified Design Question

The combination of voice messaging and unified messaging licenses on a single Cisco Unity server is not supported. If any users on the Cisco Unity server intend to immediately use unified messaging, then all of the licenses on the Cisco Unity server must be licensed for unified messaging.it is supported to have more than one Unity server in the organization to do what you are wanting to do. You could have one server for UM and the other for VM. You could then have the two digitally networked to pass messages between the two. The only caveate here is that this is for Exchange organizations. Domino is strictly UM

only.

Re: Mix and Match VMO and Unified Design Question

Hi -

If you check out this link - you will see Cisco does offer a mixed licensing model on a Unity server as of version 4.2, but you need to check out the caveats and conditions - http://www.cisco.com/en/US/customer/products/sw/voicesw/ps2237/products_white_paper09186a0080623fa8.shtml

Hope this helps.
