Mapping Subscribers to Cisco Unity Servers
Each Cisco Unity server handles a distinct group of subscribers. In large organizations, it is possible that
more than one Cisco Unity server will be in use at the same physical location. In this case, you need to
determine which subscriber accounts to create on each of the Cisco Unity servers (the “home”
Cisco Unity server for each subscriber), and keep a record of the mapping. This record is needed for the
following reasons:
Subscriber phones must forward calls to the Cisco Unity server on which the subscribers are homed.
If subscriber phones have a “Messages” or a speed-dial button that dials the number to access
Cisco Unity, the buttons must be configured to call the Cisco Unity server on which the subscribers
are homed.
To check their messages, subscribers must dial the Cisco Unity server that they are associated with;
therefore you need to tell subscribers the correct number to dial when calling into Cisco Unity. Note
that if your Cisco Unity servers are integrated with Cisco Unified Communications Manager (CM)
(formerly known as Cisco Unified CallManager), you may want to configure cross-server logon. For
more information, see the “Cross-Server Logon, Transfers, and Live Reply” chapter.
To create a record of the mapping, run the Subscribers report on each Cisco Unity server. The
information in this report includes the subscriber name and primary location. See the “Subscribers
Report” section in the “Reports” chapter of the Maintenance Guide for Cisco Unity for more
information. (The Maintenance Guide for Cisco Unity is available at
