Chapter 2 Cisco Unity Concepts

Hardware Components of a Cisco Unity System

Cisco Unity can also be integrated with multiple telephone systems. For more information, see the Multiple Telephone System Integrations Guide for Cisco Unity 5.0 at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_g uides_list.html.

One or More Cisco Unity Servers

For a detailed list of servers that are qualified for use with Cisco Unity, see the Cisco Unity Supported Platforms List at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_data_sheets_list.html.

Each qualified Cisco Unity server can service a specified number of Cisco Unity subscribers depending on the type of server and, for Voice Messaging configurations, depending on whether Exchange is installed on the Cisco Unity server. The Cisco Unity Supported Platforms List indicates how many subscribers can be serviced by each type of server.

For Unified Messaging configurations, at least one Cisco Unity server is required for each:

•Domino domain

•Exchange organization

If the customer purchases Cisco Unity failover, two Cisco Unity servers are required:

•The primary server, which takes calls the majority of the time; and

•The secondary server, which takes calls when the customer wants to perform maintenance on the primary server or when the primary server stops functioning for any reason.

If the customer purchases Voice Recognition licenses, one voice-recognition server is required for each Cisco Unity server. For a list of servers that are qualified as voice-recognition servers, see the

Cisco Unity Supported Platforms List at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_data_sheets_list.html.

Note Voice recognition is not supported with phone system integrations that use voice cards.

Voice Cards or PIMG Units (Required for Integrations with Circuit-Switched Phone Systems)

If the customer integrates Cisco Unity with a circuit-switched phone system, either voice cards or PIMG units are required. For a list of supported voice cards, see the Supported Hardware and Software, and Support Policies for Cisco Unity Release 5.x at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

Expansion Chassis (Required Only for Some Integrations with Circuit-Switched Phone Systems)

If the customer is integrating Cisco Unity with a circuit-switched phone system and needs more voice cards than will fit in the Cisco Unity server, an expansion chassis is required for the voice cards (see the

Cisco Unity Supported Platforms List at
