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.
