Chapter 2 Cisco Unity Concepts
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.
