Hardware Components of a Cisco Unity System

The message store contains only Cisco Unity voice messages, not e-mails or faxes.

Exchange can be installed either on the Cisco Unity server or on a separate server, depending on the number of subscribers that need to be supported by Cisco Unity. Domino must be installed on a separate server.

•Subscribers check messages:

–With Domino or Exchange, by using the phone or Cisco Personal Communicator.

–With Exchange, by using the Cisco Unity Inbox (accessed through the Cisco PCA) or an IMAP e-mail client.

•E-mail attributes, if any, and voice mail attributes on subscriber accounts must be administered separately.

•Cisco Unity can play back electronic messages over the phone by using Text to Speech, and can support identifying, redirecting, and printing third-party faxes.

Cisco Unified Communications Manager or Another Supported Phone System

Cisco Unity can be integrated with Cisco Unified Communications Manager (Cisco Unified CM) or another supported phone system. For a list of supported phone systems, see the applicable version of Supported Hardware and Software, and Support Policies for Cisco Unity at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

For integrations with circuit-switched phone systems, the customer may require special cables, line splitters, and so on. For more information, see the integration guide for the phone system that the customer uses. Cisco Unity integration guides are available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_g uides_list.html.
