Chapter 5 AMIS Networking
AMIS Concepts and Definitions
• There could be times during the day when the number of AMIS messages spikes. The storage limit
must be high enough to handle this.
• If hard disk space on the Exchange server is limited, you may want to set a limit to ensure that
available space is not exceeded.
You may want to monitor the outgoing AMIS message traffic by running the AMIS Out Traffic Report
before setting limits on the UAmis mailbox. For more information, see the “AMIS Out Traffic Report”
section in the “Reports” chapter of the Maintenance Guide for Cisco Unity. The Maintenance Guide for
Cisco Unity is available at
http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_maintenance_guides_list.html.
The UAmis mailbox can be moved and deleted just like any other Exchange mailbox, by using standard
Microsoft tools. Be sure to let anyone who administers Active Directory and Exchange know about the
UAmis account so that it is not moved or deleted by mistake. To avoid inadvertently moving or deleting
the UAmis account, consider changing the Exchange display name so that the account is more clearly
identified to you or the Exchange administrator as requiring “special” treatment. You can also hide the
UAmis account so that it does not appear in the Outlook address book.
For information on moving the UAmis mailbox, see the “UAmis Mailbox” section in the “Cisco Unity
Data and Log Files” chapter of the Maintenance Guide for Cisco Unity, at
http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_maintenance_guides_list.html.
Messages are sent from the UAmis mailbox at one or more of the following times:
• When a message is marked urgent, and the AMIS delivery option settings allow urgent messages to
be sent immediately.
• When the AMIS restriction table allows the delivery number of a message.
• When the AMIS schedule becomes active.
Messages that have not been sent when the schedule becomes inactive remain in the UAmis mailbox until
the schedule becomes active again. An error is logged in the Windows Application Event log when
messages remain in the UAmis mailbox for more than 24 hours. See the “Maintenance” section on
page 5-40 for information about monitoring the UAmis mailbox.
In organizations with multiple Cisco Unity servers networked together, the UAmis account needs to be
created only on those Cisco Unity servers that will place and receive AMIS calls. See the
“Considerations for Networked Cisco Unity Servers” section on page 5-38 for more information.
Voice Connector and AMIS Networking
The Voice Connector allows Cisco Unity to send and receive AMIS messages. When subscribers use the
phone to address a message to an AMIS recipient, Cisco Unity constructs an address with the form
AMIS:<Location Dial ID>_<Remote Mailbox> for the message. The Voice Connector is registered with
Exchange to handle messages with the AMIS address type. For an outbound message to an AMIS
recipient, the Voice Connector transforms the message properties and delivers the message to the UAmis
mailbox. For installations with multiple Cisco Unity servers that are licensed for AMIS, the Voice
Connector delivers the message to the UAmis mailbox that is associated with the Cisco Unity server on
which the AMIS location or AMIS subscriber was created.
Install the Voice Connector for Exchange 2000. See the “Setting Up the Voice Connector for AMIS
Networking” section on page 5-4 for information about setting up the Voice Connector.
The Voice Connector for Exchange 2000 version 11.0(1) or later can be installed on either an
Exchange 2000 or Exchange 2003 server.
Installing the Voice Connector on an Exchange 2007 server is not supported.
