Chapter 5 AMIS Networking
AMIS Concepts and Definitions
Note the following:
• Live reply to AMIS subscribers is enabled automatically, and cannot be disabled.
• Live replies to AMIS subscribers with accounts on other Cisco Unity servers do not use the
cross-server live reply functionality that can be used to live reply to Cisco Unity subscribers with
accounts on other Cisco Unity servers. However, for live reply to be offered when a Cisco Unity
subscriber replies to a message from an AMIS subscriber with a subscriber account on another
Cisco Unity server, the servers must be in the same dialing domain.
Deleting AMIS Subscribers
Each AMIS subscriber is associated with an Active Directory contact. When you delete AMIS
subscribers in the Cisco Unity Administrator by deleting the subscriber accounts individually, the
underlying directory objects are automatically deleted. To delete all of the AMIS subscribers that are
associated with a delivery location, the underlying contacts for those subscribers, and the delivery
location itself, use the Global Subscriber Manager, available in Tools Depot.
Note that when you delete an AMIS delivery location, blind addressees are also removed from all private
lists. Consider notifying subscribers of these potential changes to their private lists.
Extension Addresses
When you create an AMIS subscriber, Cisco Unity automatically generates an e-mail address in the
following format:
AMIS:<Location Dial ID>_<Remote Mailbox>
This special e-mail address is referred to as an extension address (or a remote address). The extension
address is a combination of the delivery location Dial ID with which the AMIS subscriber is associated,
and the Remote Mailbox Number of the AMIS subscriber. Each contact in Active Directory that
corresponds to an AMIS subscriber contains an extension address.
When subscribers use the phone to address messages to an AMIS subscriber, they dial an extension.
Cisco Unity recognizes the recipient as an AMIS subscriber and retrieves the extension address from the
SQL Server database on the Cisco Unity server.
Extension addresses are generated automatically when you create AMIS subscribers, and are
automatically updated if you change the Dial ID of a delivery location or the remote mailbox number.
Determining How AMIS 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 AMIS 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 AMIS 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
