Cisco Systems 5.x manual Considerations for Digitally Networked Cisco Unity Servers

Chapter 7 VPIM Networking

VPIM Concepts and Definitions

4.Run Global Subscriber Manager from Tools Depot to delete the VPIM delivery locations and the associated VPIM subscribers and underlying contacts.

5.If the people migrating from the remote voice messaging system do not already have Active Directory accounts and Exchange mailboxes, create them. Alternatively, you can let the Cisco Unity Bulk Import wizard create the accounts.

6.Run the Cisco Unity Bulk Import wizard by using the input file that you prepared in Step 3.

Migrating Subscribers One at a Time

If you have set up VPIM subscriber accounts for the subscribers on another voice messaging system, and if they have existing Exchange mailboxes, you can use the Migrate Subscriber Data utility when the time comes to migrate them to Cisco Unity. The Migrate Subscriber Data utility creates a Cisco Unity subscriber account by combining the Cisco Unity-specific data from an existing VPIM subscriber account (such as the voice name) with an existing mail user. The utility then deletes the VPIM subscriber account and the associated Active Directory contact.

The Migrate Subscriber Data utility is available in Tools Depot (the Tools Depot icon is installed on the Cisco Unity server desktop). See the Help file that comes with the utility for more information.

Private List Considerations for Migrating Subscribers

When you migrate VPIM subscribers, consider notifying Cisco Unity subscribers of these potential effects on private distribution list membership:

•When you delete a delivery location, blind addressees are removed from all private lists.

•When a VPIM subscriber becomes a regular subscriber, the VPIM subscriber is removed from all private lists.

Considerations for Digitally Networked Cisco Unity Servers

A small subset of subscriber and distribution list data is stored in Active Directory, as is most location data. In organizations with multiple Cisco Unity servers networked together such that they access a common directory, the Cisco Unity-specific data replicates to all Cisco Unity servers in the network. Therefore, all Cisco Unity servers on the network have the information that subscribers need to address messages to users at a VPIM location.

Because of directory replication, VPIM delivery locations and VPIM subscribers need to be created only on one Cisco Unity server in the network. If allowed by the primary location addressing options on each server, all subscribers, no matter which Cisco Unity server they are associated with, can send messages to a VPIM delivery location or to a VPIM subscriber created on another server. The Cisco Unity server configured for VPIM acts as the VPIM “bridgehead” server for the other Cisco Unity servers in the network.
