About Annunciator Setup
In Cisco Unified Communications Manager Administration, use the menu path to configure annunciators.
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 Tips
Verify that you have activated the Cisco IP Voice Media Streaming Application service on the server where you plan to configure the annunciator. For information on activating services, see the Cisco Unified Serviceability Administration Guide.
Tip |
When you add a Cisco Unified Communications Manager server, the annunciator for the sever automatically gets added to the database. After you activate the Cisco IP Voice Media Streaming Application service, the annunciator device registers with Cisco Unified Communications Manager. |
Tip |
The annunciator provided by the Cisco IP Voice Media Streaming Application service supports both IPv4 and IPv6 audio media connections. The annunciator is configured automatically in dual mode when the platform is configured for IPv6 and the IPv6 enterprise parameter is enabled. The annunciator supports only IPv4 for the TCP control channel. The annunciator supports secure media SRTP connections to both IPv4 and IPv6 addresses. |
Before you begin to configure an annunciator, verify that you have completed the following tasks:
-
Configured the appropriate servers
-
Configured device pools
