Procedures for Setting Up Cisco Unity to Use VPIM Networking
Extending Identified Subscriber Messaging to Include VPIM Subscribers
When a person on a remote voice messaging system who has a corresponding VPIM subscriber account
calls a Cisco Unity subscriber and leaves a message, by default Cisco Unity will not identify the message
as being from the VPIM subscriber. For Cisco Unity to identify callers whose calling number matches
the extension or alternate extension of a VPIM subscriber, identified subscriber messaging (ISM) must
be extended to include VPIM subscribers. See the following sections as applicable to your installation.
• Installation with Multiple Cisco Unity Servers Networked via Digital Networking, page 7-34
• Single-Server Installations, page 7-34
• Setting Permissions on Active Directory Containers Used for Importing Subscribers, page 7-35
• Enabling Identified Subscriber Messaging, page 7-35
• Extending Identified Subscriber Messaging, page 7-36

Installation with Multiple Cisco Unity Servers Networked via Digital Networking

In installations with multiple Cisco Unity servers networked via Digital Networking, enabling ISM to
include VPIM subscribers requires the following:
1. The Cisco Unity servers must be connected to the same phone system or phone system network as
described in the “Dialing Domains” section on page 2-15.
2. The servers must be configured to be in the same dialing domain, as described in the “Customizing
the Primary Location” section on page 7-18.
3. The automated attendant search scope on each server must be set to the dialing domain as described
in the “Setting the Automated Attendant Search Scope” section on page 2-7.
4. The applicable permissions on each server must be set, as described in the “Setting Permissions on
Active Directory Containers Used for Importing Subscribers” section on page 7-35.
5. Identified subscriber messaging on each server must be enabled as described in the “Enabling
Identified Subscriber Messaging” section on page 7-35.
6. Identified subscriber messaging on each server must be enabled for VPIM subscribers as described
in the “Extending Identified Subscriber Messaging” section on page 7-36.

Single-Server Installations

In installations with only one Cisco Unity server, enabling ISM to include VPIM subscribers requires
the following:
1. The server must be configured with a dialing domain name, as described in the “Customizing the
Primary Location” section on page 7-18.
2. The applicable permissions must be set, as described in the “Setting Permissions on Active
Directory Containers Used for Importing Subscribers” section on page 7-35.
3. Identified subscriber messaging must be enabled as described in the “Enabling Identified Subscriber
Messaging” section on page 7-35.
4. Identified subscriber messaging must be enabled for VPIM subscribers as described in the
“Extending Identified Subscriber Messaging” section on page 7-36.
