An annunciator, an SCCP device that uses the Cisco Media Streaming Application service, enables Cisco Unified Communications Manager to play prerecorded announcements (.wav files) and tones to Cisco Unified IP Phones and gateways. The annunciator, which works with Cisco Multilevel Precedence and Preemption (MLPP), enables Cisco Unified Communications Manager to alert callers as to why the call fails. Annunciator can also play tones for some transferred calls and some conferences.

Annunciator Configuration Settings

An annunciator, an SCCP device that uses the Cisco Media Streaming Application service, enables Cisco Unified Communications Manager to play prerecorded announcements (.wav files) and tones to Cisco Unified IP Phones and gateways. The annunciator, which works with Cisco Multilevel Precedence and Preemption (MLPP), enables Cisco Unified Communications Manager to alert callers as to why the call fails. Annunciator can also play tones for some transferred calls and some conferences.

Before You Begin

Verify that you have activated the Cisco IP Voice Media Streaming Application service on the server where you plan to configure the annunciator.

---

Tip When you add a Cisco Unified Communications Manager server, the annunciator for the server will automatically get added to the database. After you activate the Cisco IP Voice Media Streaming Application service, the annunciator device registers with Cisco Unified Communications Manager. Verify whether the annunciator exists by using the "Finding an Annunciator" section.

---

Verify that you have completed the following tasks:

•Configured the appropriate servers

•Configured device pools

Table 72-1 describes the annunciator configuration settings. For more information about related procedures, see the "Related Topics" section.

Table 72-1 Annunciator Configuration Settings 

Field	Description
Server	The system automatically displays the preconfigured server (servers get added at installation).
Name	This field designates the name that is used when the device registers with the Cisco Unified Communications Manager. Enter a name of up to 15 alphanumeric characters (you can use periods, dashes, and underscores).
Description	Enter a description of up to 128 alphanumeric characters (you can use periods, dashes, and underscores). Default uses the server name, which includes the prefix ANN_.
Device Pool	Choose Default or choose a device pool from the drop-down list of configured device pools.
Location	Use locations to implement call admission control (CAC) in a centralized call-processing system. CAC allows you to regulate audio quality and video availability by limiting the bandwidth that is available for audio and video calls over links between locations. The location specifies the total bandwidth that is available for calls to and from this location. From the drop-down list box, choose the appropriate location for this annunciator. A location setting of Hub_None means that the locations feature does not keep track of the bandwidth that this annunciator consumes. A location setting of Phantom specifies a location that enables successful CAC across intercluster trunks that use H.323 protocol or SIP. To configure a new location, use the System > Location menu option. For more details about locations, see the "Location Configuration" section on page 17-1. For an explanation of location-based CAC across intercluster trunks, see "Location-Based Call Admission Control Over Intercluster Trunk" in the Cisco Unified Communications Manager System Guide.
Use Trusted Relay Point	From the drop-down list box, enable or disable whether Cisco Unified Communications Manager inserts a trusted relay point (TRP) device with this media endpoint. Choose one of the following values: •Off—Choose this value to disable the use of a TRP with this device. •On—Choose this value to enable the use of a TRP with this device. A Trusted Relay Point (TRP) device designates an MTP or transcoder device that is labeled as Trusted Relay Point. Cisco Unified Communications Manager places the TRP closest to the associated endpoint device if more than one resource is needed for the endpoint (for example, a transcoder or RSVPAgent). If both TRP and MTP are required for the endpoint, TRP gets used as the required MTP. For details of call behavior, see "TRP Insertion in Cisco Unified Communications Manager" in the Cisco Unified Communications Manager System Guide. If both TRP and RSVPAgent are needed for the endpoint, Cisco Unified Communications Manager first tries to find an RSVPAgent that can also be used as a TRP. If both TRP and transcoder are needed for the endpoint, Cisco Unified Communications Manager first tries to find a transcoder that is also designated as a TRP. Refer to "Trusted Relay Point" and its subtopics in the "Media Resource Management" chapter of the Cisco Unified Communications Manager System Guide for a complete discussion of network virtualization and trusted relay points.
