Cisco Systems 5.x manual Deleting Vpim Subscribers, Extension Addresses

Chapter 7 VPIM Networking

VPIM Concepts and Definitions

Deleting VPIM Subscribers

Each VPIM subscriber is associated with an Active Directory contact. When you delete VPIM subscribers in the Cisco Unity Administrator by deleting the subscriber accounts individually, the underlying contacts are automatically deleted. To delete all of the VPIM subscribers associated with a delivery location, the underlying contacts associated with the subscribers, and the delivery location itself, use the Global Subscriber Manager, available in Tools Depot. Note that when you delete a VPIM delivery location, blind addressees are also removed from all private lists. Consider notifying subscribers of these potential changes to their private lists.

If enabled by the delivery location Subscriber Creation settings, Cisco Unity can automatically delete VPIM subscribers when non-delivery receipts are received from the delivery location in response to messages that are sent to VPIM subscribers. For further information, see the “Automatic VPIM Subscriber Directory Updates” section on page 7-46.

Extension Addresses

When you create a VPIM subscriber, Cisco Unity automatically generates an e-mail address in the following format:

VPIM:<Delivery Location Dial ID>_<Remote Mailbox Number>

This special e-mail address is called an extension address or a remote address. The extension address is a combination of the delivery location Dial ID with which the VPIM subscriber is associated, and the Remote Mailbox Number of the VPIM subscriber. Each contact in Active Directory that corresponds to a VPIM subscriber contains an extension address.

When subscribers use the phone to address messages to a VPIM subscriber, they dial an extension. Cisco Unity recognizes the recipient as a VPIM subscriber and retrieves the extension address from the SQL Server database on the Cisco Unity server.

Extension addresses are generated automatically when you create VPIM subscribers. Extension addresses are updated automatically when you change the remote mailbox number, and are automatically updated if you change the Dial ID of a delivery location.

Determining How VPIM Subscribers Appear in the Outlook Address Book

Depending on your installation, the users of the remote voice messaging system may already have Active Directory accounts and Exchange mailboxes on your local network that they use for e-mail. Therefore, when VPIM subscriber accounts are created for them, the Exchange address lists will contain duplicate listings—the existing user account that is used for e-mail and a new contact that is used only for voice mail. Both listings are included in the Outlook address book. This means that people may inadvertently send e-mail messages to the contact, which should be used only for addressing voice messages.

To discourage people from inadvertently sending e-mail messages to VPIM subscribers, you can prevent the associated contact from appearing in the Outlook address book. Alternatively, you can change how the display name for the contact appears in the Outlook address book so that subscribers can distinguish the contact from a user account. In this way, you can reduce the number of e-mail messages inadvertently sent to contacts and simplify addressing for those who send voice messages to VPIM subscribers at the same time.

Either before or after you create VPIM subscriber accounts, you can prevent the associated contact from appearing in the Outlook address book by hiding the contacts from Exchange address lists. When you do so, Exchange will still deliver e-mail messages addressed to an existing user account (if one exists)
