VPIM Concepts and Definitions
Identified Subscriber Messaging
Identified subscriber messaging (ISM) affects what subscribers hear when they call other subscribers
from their primary or alternate extensions and are forwarded to the greetings of the subscribers they call.
If they then leave a message, ISM affects what the called subscriber hears and can do when listening to
the message. When ISM is enabled, Cisco Unity recognizes that the calling extension is associated with
a subscriber and accordingly plays the internal greeting of the called subscriber. Additionally, when the
called subscriber later listens to the message, Cisco Unity plays the recorded voice name of the
subscriber who left the message and allows the called subscriber to record a reply.
When a call to a Cisco Unity subscriber is forwarded to the subscriber greeting and ISM is enabled,
Cisco Unity compares the calling number (ANI or caller ID) to the primary and alternate extensions of
subscribers. If a match is found, Cisco Unity identifies the caller as a subscriber. When Cisco Unity
compares the calling number to extensions, by default, only “regular” Cisco Unity subscribers on the
local system are included in the comparison. ISM can be expanded to include all Cisco Unity subscribers
throughout a dialing domain.
You can enable ISM for AMIS, Bridge, and VPIM subscribers (collectively referred to as external
subscribers), so that Cisco Unity will include them when comparing calling numbers to extensions. Note
the following:
• After enabling ISM for external subscribers, Cisco Unity must be restarted.
• If multiple Cisco Unity servers are networked via Digital Networking, ISM functionality can be
made available only on the Cisco Unity servers that are in the same dialing domain as the bridgehead
server.
