Hardware Requirements

A server that meets Cisco Unity specifications. Refer to the Cisco Unity Supported Platforms List at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_data_sheets_list.html.


Caution Cisco TAC does not provide any assistance for installing, customizing, or troubleshooting Cisco Unity on a platform that is not on the Cisco Unity Supported Platforms List.

Voice cards that are approved for use with Cisco Unity. (If you are integrating Cisco Unity with Cisco Unified CM, the integration does not require voice cards.) See the "Supported Voice Cards" and "Supported Other Phone System Integrations" sections in Supported Hardware and Software, and Support Policies for Cisco Unity 4.2 and Later at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/unity42/42lsupp.htm.

Some voice cards that were supported with earlier versions of Cisco Unity are no longer supported. If you are upgrading from Cisco Unity version 2.x to version 4.2 and the existing server contains unsupported voice cards, you must replace those cards to upgrade to version 4.2.

If you are installing a Cisco Unity system outside the United States and you are connecting it directly to the central office by using an analog loop, you may need to install inline telco filters on the Intel Dialogic voice cards to filter tax impulse signals. For more information, refer to the Intel Dialogic documentation and regulatory notices that ship with the voice cards.

The necessary cables, line splitters, and adapters to connect the voice cards to the phone system. For information about the cables and other components required for each type of circuit-switched phone system integration, see the "Supported Other Phone System Integrations" section in Supported Hardware and Software, and Support Policies for Cisco Unity 4.2 and Later at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/unity42/42lsupp.htm.

If you are installing cards that have H.100 connectors, you need to connect the cards by using an H.100 cable that has at least as many connectors as you have cards (you must connect all cards by using a single cable) but no more than five extra connectors.
