Message Administrator by using the options in Table 2-1, which result in a system broadcast being
transmitted to all subscribers on the local server or to all subscribers on multiple servers within the
directory.
Individual Cisco Unity servers within the directory can be added by location dial ID as shown in the
example above. Public distribution lists are only used for sending system broadcast messages to VPIM
locations. For more information on sending system broadcast messages by using VPIM, see the
“Addressing System Broadcast Messages to Multiple Servers” section on page 8-7.
Note that when a system broadcast message is sent to multiple locations, a copy of the message is sent
to each server and then distributed to the subscribers who are homed on that server. As a result, the
subscriber who is sending the system broadcast message must make updates to each message locally. In
this example, after the ChicagoUnity subscriber has sent a message, if updates need to be made to any
properties on the message at a later time, he or she would need to have permission to log on to the
Cisco Unity Broadcast Administrator on each server to make the updates.
How Networked System Broadcast Messages are Processed by Cisco Unity
When Cisco Unity is installed, a new Windows service called CsBMessageConnector is created, along
with a special mailbox that has the display name USbms_<Servername>. The USbms mailbox is created
in the default directory container for Cisco Unity, and is hidden from the address book. The
CsBMessageConnector service processes messages that are placed in the USBms mailbox. For systems
that use failover, the CsBMessageConnector service runs on both the primary and secondary servers, and
both services access the same USbms mailbox, but only the service on the currently active server will
process messages.
When a system broadcast message is addressed to multiple Cisco Unity servers, a copy of the message
is placed in the USbms mailbox for each server; the CsBMessageConnector service on each server
processes the message and makes it available to all Cisco Unity subscribers on the server, based on the
start and end dates configured for the message.
