46 Chapter 2: Using Your Cisco Uniﬁed Communications System
To beneﬁt fully from this section, it is recommended that you have the following prerequisite
skills and knowledge. (If you need a quick review, see the designated chapter, where you can
ﬁnd more information on the topic.)
• Knowledge of how calls are handled in a Cisco Unity system (See Chapter 5, “Uniﬁed
Communications System Customization”)
• Knowledge of the interaction between Cisco Unity and Microsoft Exchange/Active
Directory and/or Lotus Domino (see Chapter 8, “Cisco Uniﬁed Communications System
When an inbound call arrives, it is processed by a telephone system like Cisco CallManager.
You can have a Cisco CallManager interact with the Cisco Unity system and pass along any
pertinent information that can be provided. This may include caller ID, name of the caller, or
other information. The information passed is dependent on Cisco CallManager and its
conﬁguration. Once the Cisco Unity system receives the call, numerous possibilities can be
explored in handling the call.
Upon seeing that the call is not sourced from a conﬁgured Cisco Unity subscriber, the Standard
Opening Greeting is played to the caller. In cases where a subscriber-to-subscriber call is being
made, the caller simply hears the subscriber conversation as conﬁgured by the individual.
Understanding the TUI
When the Cisco Unity System receives a call from an outside caller, the caller hears the Cisco
Unity conversation, a prerecorded set of instructions and options that is made available to
callers and subscribers to meet the needs of each. The Cisco Unity conversation enables the
caller to access the Cisco Unity Automated Attendant, conduct subscriber searches using
directory assistance, use call-routing options, and play audiotext messages. Subscribers hear the
subscriber conversation, which enables them to enroll as new subscribers, send or receive
messages, record greetings, and change personal settings.
For subscribers, there are two types of conversations, the standard conversation and the optional
conversation. The standard conversation is the default subscriber conversation. The optional
conversation allows subscribers to hear message-retrieval menus that closely resemble
traditional voice-messaging choices with which they may be familiar. The optional
conversation needs to be activated to use it.
As a best practice, you should always conﬁgure an option to “0-out” during the personal
greeting or while in the Auto Attendant to get a human operator. There are a number of options
that can be conﬁgured using one-key dialing beyond the simple operator functionality.
