# Presence Overview

The Speech Auto Attendant feature provides the ability to optionally play back the current presence state of the matched person prior to transferring the caller. A caller hears the user’s current presence state, spoken by the Speech Auto Attendant, before being transferred to the user’s phone. For example, SAA might say, "Alice Brown is currently Away.” before transferring the call to Alice Brown's phone.

Note: The Presence feature is only supported with installations that use Active Directory as their user repository. See User Data Sources for more information.

Presence status information is for reference only, so a call will be transferred regardless of presence status. Standard universal barge-in commands such as "cancel" and "help" during a call transfer are supported.

The presence status information is optional. It is enabled by default for both internal and external callers, and is independent of whether the caller is trusted or non-trusted. It can be turned off using the Presence for Internal Callers and Presence for External Callers check boxes in the Miscellaneous Parameters menu of the Web Console.

### Server Support

The presence feature in Release 4.0 and later supports the Microsoft Live Communication server (LCS 2005 SP2), Office Communications server 2007, and Mitel MiCollab Client Service.

### Licensing

This feature is licensed as a single license, “NuPoint Messenger: Enable Presence (Speech AA)”, which enables Presence on the system. The license can be activated at any time and becomes available within one minute of activation. No reboot or restart is necessary.

### Installation

Presence information is supplied to the Speech Auto Attendant by the Presence Proxy service. The Presence Proxy is part of the NuPoint Unified Messaging system, and is installed using the “NPMPresence” blade. See Presence Installation for more information.
