Cisco Systems 5.x manual Live Reply to Vpim Subscribers

Chapter 7 VPIM Networking

VPIM Concepts and Definitions

•You must enable ISM for external subscribers for each Cisco Unity server on which the functionality is desired.

•If a single Cisco Unity server is in use, the Cisco Unity server must be a member of a dialing domain for this functionality to be used.

Note the difference between leaving a messaging and sending a message. When a person on the remote voice messaging system with a corresponding external subscriber account records and sends a message to a Cisco Unity subscriber (as opposed to calling and leaving a message), all versions of Cisco Unity identify the message as being from the corresponding external subscriber.

The phone system provides the calling number to Cisco Unity. The number of digits included in the calling number is configurable in most phone systems. For Cisco Unity to find a matching subscriber extension, the phone system must be configured to provide the applicable number of digits in the calling number. You may also need to add alternate extensions to the subscriber accounts to match the calling number. Additionally, there may be other phone system-specific issues that prevent Cisco Unity from matching the calling number to a subscriber extension. Refer to your phone system documentation and the applicable Cisco Unity integration guide for details about the call information provided by the phone system.

Live Reply to VPIM Subscribers

Live reply allows subscribers who listen to their messages by phone to respond to messages from other subscribers by calling them. When live reply is enabled, subscribers listening to messages by phone can reply to a subscriber message choosing the “call the subscriber” option to have Cisco Unity call the subscriber directly. Note that whether subscribers have access to the live reply feature depends on their class of service settings. (Live reply is enabled on the Subscribers > Class of Service > Messages page in the Cisco Unity Administrator.)

Subscribers can live reply to messages from subscribers on other voice messaging systems who have corresponding VPIM subscriber accounts in Cisco Unity. In order for the live reply call to be successfully transferred, a call transfer number must be configured for the VPIM subscribers.

Note that a live reply to a VPIM subscriber is always done via a release to phone system transfer, even when both the Cisco Unity subscriber who is replying to a message and the VPIM subscriber have accounts on the same Cisco Unity server. On a release to switch transfer, Cisco Unity dials the call transfer number configured for the VPIM subscriber and hangs up, leaving the phone system to handle the call. Note the following limitations with release to switch transfers:

•The VPIM subscriber call screening, call holding, and announce features are ignored.

•The call transfer setting “No (Send Directly to Subscriber's Greeting)” is ignored. Cisco Unity dials the VPIM subscriber extension and hangs up. If the subscriber extension is a valid extension on the phone system that Cisco Unity is integrated with, then the subscriber phone rings. If the subscriber extension is not a valid phone extension, what happens to the call after that depends on the phone system and how it is configured. If you do not configure the phone system to handle calls to the subscriber extensions, the caller may be disconnected.

Note the following:

•Live reply to VPIM subscribers is enabled automatically, and cannot be disabled.

•Live replies to VPIM 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 a VPIM subscriber with a subscriber account on another Cisco Unity server, the servers must be in the same dialing domain.
