One or More Message-Store Servers (Optional for Some Configurations)

For Cisco Unity systems configured for Unified Messaging, the message store software (IBM Lotus Domino or Microsoft Exchange) must be installed on a server other than the Cisco Unity server.

For Cisco Unity systems configured for Voice Messaging, Exchange can be installed on the Cisco Unity server or on a separate server. Domino must be installed on a separate server.

The number of subscribers homed on the Cisco Unity server cannot exceed the maximum listed for that type of server on the Cisco Unity Supported Platforms List at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_data_sheets_list.html.

One or More Dedicated Domain Controllers/Global Catalog Servers (Exchange Only, Large Voice Messaging Configurations Only)

For large Voice Messaging configurations, one or more dedicated domain controllers/global catalog (DC/GC) servers may be required. For more information, see Chapter 3, “Network Infrastructure Requirements.”

Cisco Unity Bridge Server (Required Only for Interoperating with Avaya Voice Messaging Systems)

If the customer wants Cisco Unity to interoperate with an Avaya voice messaging system, a dedicated Cisco Unity Bridge server is required. For more information, see the following documents:

•For information on how Cisco Unity can send voice messages to Avaya and receive voice messages from Avaya, see the applicable version of the Networking Guide for Cisco Unity Bridge at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guides_list.html.

•For requirements for connecting Cisco Unity and Avaya, see the System Requirements, and Supported Hardware and Software for Cisco Unity Bridge at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

Network Connection (Optional for Some Configurations)

For Cisco Unity systems that are configured for Unified Messaging, a network connection is required.

For Cisco Unity systems that are configured for Voice Messaging, a network connection is required only if the customer wants to do one or more of the following:

•Use Domino for the message store.

•Integrate Cisco Unity with an IP phone system (for example, Cisco Unified Communications Manager).
