Annunciator Configuration
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.
Use the following topics to find and update annunciators:
• Annunciator Configuration Settings, page 72-1
• Finding an Annunciator, page 72-3
• Updating an Annunciator, page 72-4
• Resetting an Annunciator, page 72-5

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 on page 72-3.
