Chapter 8 Using VPIM for Networking with Cisco Unity Express or Other Cisco Unity Systems
Messaging Between Cisco Unity Servers in Different Directories
Correspondence Between Locations
As Figure 8-1 illustrates, you create a VPIM delivery location on the local Cisco Unity server to
correspond to each remote Cisco Unity Bridgehead server. Typically, the Domain Name that you enter
on the delivery location matches the Domain Name for the corresponding primary location on the remote
Cisco Unity server and vice versa. However, the domain names that you enter depend on your e-mail
addresses/recipient policy. In addition, the Dial ID and Display Name on the local delivery location are
typically the same as the Dial ID and Display Name on the remote primary location and vice versa (this
is for convenience only and is not a requirement). If prefixes are needed to accommodate numbering
plans and subscriber dialing habits, enter applicable prefixes on the local and/or remote delivery
locations.
Figure 8-1 Correspondence Between Locations
VPIM Subscribers Correspond to Remote Cisco Unity Subscribers
If you do not want to use blind addressing, you can create VPIM subscriber accounts on the local server
that correspond to subscribers on the remote Cisco Unity server. On the remote Cisco Unity server,
VPIM subscriber accounts can be created that correspond to the Cisco Unity subscribers on your local
server. Figure 8-2 illustrates the relationship of VPIM subscribers to remote Cisco Unity subscribers.
By creating VPIM subscribers, you manually duplicate the subscriber directory of the remote
Cisco Unity server on the local server, and vice versa. Such a setup provides the benefits listed in the
“Subscriber Experience with VPIM Subscribers” section on page 7-45.
In addition to manually creating VPIM subscribers, you can configure Cisco Unity to automatically
update the VPIM subscriber directory based on information contained in VPIM messages that are
received from the remote Cisco Unity server. You configure the settings for automatic directory updates
on the delivery location that corresponds to the remote Cisco Unity server. If the remote Cisco Unity
server is configured to include the vCard of the sender in outgoing messages, you can specify that the
vCard be used as the source of information for the directory update. Otherwise, the message headers can
be used instead. By default, no automatic directory updates will occur. For further information about
enabling automatic updates and configuring these settings, see the “Customizing VPIM Subscriber
Directory Update Settings” section on page 7-28.
