Digital Networking Concepts and Definitions
By default, each Unaddressed Messages and System Event Messages distribution list has the same
recorded voice name, but they are not assigned an extension because subscribers typically do not address
messages to these lists.
Private Lists
When creating private lists, subscribers can add members from other locations if allowed by the
Addressing Options settings for your default location. The location addressing options allow you to
control the search that Cisco Unity performs when a subscriber adds members to a private list and when
a subscriber addresses a message. For more information, see the “Primary Location Addressing Option
Settings” section on page 9-3.
Consider notifying subscribers in the event that the following members are inadvertently removed from
their lists:
• When you delete a delivery location, blind addressees are removed from all private lists.
• When an external subscriber (that is, an AMIS, Bridge, or VPIM subscriber) becomes a regular
subscriber, the external subscriber is removed from all private lists.
System Broadcast Messages
System broadcast messages are recorded announcements that are sent to everyone in an organization (or
to particular location(s) within an organization). System broadcast messages are played immediately
after subscribers log on to Cisco Unity by phone—even before they hear message counts for new and
saved messages. Subscribers must listen to each system broadcast message in its entirety before
Cisco Unity allows them to hear new and saved messages or to change setup options. They cannot
fast-forward or skip a system broadcast message.
System broadcast messages do not light message waiting indicators (MWIs) on subscriber phones, nor
do they cause distinctive dial tones to notify subscribers of a new message when they pick up their desk
phone receiver. System broadcast messages also do not trigger message notifications for alternative
devices, such as a pager or another phone.
System broadcast messages can be networked to all subscribers on one or more Cisco Unity servers that
access the same subscriber directory by using Digital Networking. In organizations where there are
multiple Cisco Unity or Cisco Unity Express servers that access different directories, system broadcast
messages can be sent to all subscribers in the organization (or to all subscribers who are associated with
specific sets of digitally networked servers), provided that the networks are connected by using the
VPIM Networking option.

Addressing System Broadcast Messages to Digitally Networked Servers

Depending on the desired set of recipients and the options selected in the Cisco Unity Broadcast
Administrator, a subscriber who has been granted permission to send system broadcast messages to
subscribers on multiple servers can address messages to all subscribers on the local server, to all
subscribers on one or more digitally networked servers, or to all subscribers on all servers in the domain
by using Digital Networking.
For example, consider a situation in which three Cisco Unity servers share the same directory. The
servers are named ChicagoUnity (dial ID 344), NewYorkUnity (dial ID 444), and AtlantaUnity (dial ID
544). A subscriber on ChicagoUnity who has been granted permission to send system broadcast
messages to subscribers on multiple servers can address a message from the Cisco Unity Broadcast
