[This is preliminary documentation and is subject to change. Blank topics are included as placeholders.]

Creates a new Microsoft Communications Server 2010 announcement. Announcements are played when users dial a valid but unassigned phone number. With announcements, users who dial one of these numbers can be given a message (such as "This number is temporarily out of service") or can be presented with a busy signal.

Parameter Required Type Description



Xds Identity

A unique identifier for the Announcement. For this value you must enter the Identity of the Application Server running the Response Group application. For example, ApplicationServer:redmond.litwareinc.com.

More than one Announcement can be assigned to a single service. Because of that, in order to make the Identity a unique value a globally unique identifier (GUID) will be automatically generated and assigned to the Identity when you create the Announcement. The new Announcement will have an Identity in the format service:<service ID>/<GUID>. For example: service: ApplicationServer:redmond.litwareinc.com/bef5fa3b-3c97-4af0-abe7-611deee7616c. You do not need to supply a GUID when you call this cmdlet; simply supply the service Identity, and the GUID will be auto-generated and added to the Identity.

You don’t have to supply a GUID, but you can. You might want to do this if an announcement was assigned to an unassigned number range, then the announcement was deleted. You can create a new announcement with a matching Identity (including the GUID) and in that case not have to update the unassigned number range.




This parameter is identical to Identity, except that Identity will accept the service Identity and the GUID, whereas Parent will accept only the service Identity and the GUID will be automatically generated. You cannot specify an Identity and a Parent.




A descriptive name for the Announcement. This name must be unique within the service. This name will be used in the call to New-CsUnassignedNumber or Set-CsUnassignedNumber to specify the Announcement associated with an unassigned number range.




The name of the audio file to be played for the announcement. Audio files are stored in the File Store. To save an audio file to the File Store, use the Import-CsAnnouncementFile cmdlet.

Valid file types: WAV and WMA




A text-to-speech (TTS) prompt. This is a string that will be converted to audio and played as the announcement.

If both AudioFilePrompt and TextToSpeechPromp are specified for a single announcement, you will receive a warning that the audio file will take precedence and the TTS prompt will be ignored.

Maximum length: 4096 characters.




The language in which the TTS prompt will be played. If a value is entered for TextToSpeechPrompt this parameter is required.

Values are entered as a string representing the language and locale to be used. The following is a list of valid values, followed by the language and locale in parentheses (): ca-ES (Catalan, Catalan); da-DK (Danish, Denmark); de-DE (German, Germany); en-AU (English, Australia); en-CA (English, Canada); en-GB (English, United Kingdom); en-IN (English, India); en-US (English, United States); es-ES (Spanish, Spain); es-MX (Spanish, Mexico); fi-FI (Finnish, Finland); fr-CA (French, Canada); fr-FR (French, France); it-IT (Italian, Italy); ja-JP (Japanese, Japan); ko-KR (Korean, Korea); nb-NO (Norwegian, Bokmal, Norway); nl-NL (Dutch, Netherlands); pl-PL (Polish, Poland); pt-BR (Portuguese, Brazil); pt-PT (Portuguese, Portugal); ru-RU (Russian, Russia); sv-SE (Swedish, Sweden); zh-CN (Chinese, People’s Republic of China); zh-HK (Chinese, Hong Kong S.A.R.); zh-TW (Chinese, Taiwan)




The URI to which the caller will be transferred after the announcement has been played. This value must be a SIP address entered in the format sip: followed by the SIP address. For example, sip:kmyer@litwareinc.com. Note that the SIP address can also be a telephone number, for example +14255551212@litwareinc.com;user=phone for a phone number of kmyer@litwareinc.com;opaque=app:voicemail for voicemail.



Switch Parameter

Creates an object reference without actually committing the object as a permanent change. If you assign the output of this cmdlet called with this parameter to a variable, you can make changes to the properties of the object reference and then commit those changes by calling this cmdlet’s matching Set- cmdlet.



Switch Parameter

Describes what would happen if you executed the command without actually executing the command.


Switch Parameter

Prompts you for confirmation before executing the command.




Suppresses any confirmation prompts that would otherwise be displayed before making changes.

Detailed Description

An enterprise can own phone numbers that are not assigned to users or phones, but which are still valid numbers that can be called. By default when someone dials one of those numbers he or she will receive a busy signal and the call may result in an error returned to the SIP client. By applying announcement settings to unassigned numbers, administrators have the option of playing a message, returning a busy signal, or redirecting the call. This cmdlet creates these announcement settings.

You can assign announcements to unassigned numbers by calling the New-CsUnassignedNumber or Set-CsUnassignedNumber cmdlet.

Available scopes: Service (Application Server only)

Return Types

Creates an object of type Microsoft.Rtc.Management.WritableConfig.Settings.AnnouncementServiceSettings.Announcement.


-------------------------- Example 1 ------------------------

Copy Code
New-CsAnnouncement -Identity ApplicationServer:redmond.litwareinc.com -Name "Help Desk Announcement" -TextToSpeechPrompt "Welcome to the Help Desk." -Language "en-US"

Example 1 demonstrates how you can create a new announcement that will play a TTS prompt in English (U.S.). The first parameter we specify is Identity. The Identity must be at the service scope, followed by the service ID of the Application Server (ApplicationServer:redmond.litwareinc.com). Next we give the announcement a Name, in this case Help Desk Announcement. To assign a TTS prompt to this announcement we use the TextToSpeechPrompt parameter followed by a string (up to 4096 characters) with the announcement text. When a TTS prompt is used for an announcement you must specify a language, which we do here by including the Language parameter followed by a string representing U.S. English (en-US).

Note that announcement identities are composed of two parts: the service where the announcement is to be stored, and a 36-character GUID (globally unique identifier). You will see the full Identity after you create the new announcement, the GUID is generated and applied automatically. That Identity will be similar to this: service:ApplicationServer:redmond.litwareinc.com/1951f734-c80f-4fb2-965d-51807c792b90.

-------------------------- Example 2 ------------------------

Copy Code
New-CsAnnouncement -Identity ApplicationServer:redmond.litwareinc.com -Name "Welcome Announcement" -AudioFilePrompt "WelcomeMessage.wav"

Example 2 is similar to Example 1 in that we begin by entering the required parameters, Identity and Name. In this example, however, instead of a TTS prompt we want the announcement to play an audio file. To do that we include the AudioFilePrompt parameter and pass it a string containing the name of the audio file (WelcomeMessage.wav). This file must be in the File Store in order for this announcement to play. You can add audio files to the File Store by calling the Import-CsAnnouncementFile cmdlet.

-------------------------- Example 3 ------------------------

Copy Code
New-CsAnnouncement -Identity ApplicationServer:redmond.litwareinc.com -Name "Forward Announcement" -AudioFilePrompt "WelcomeMessage.wav" -TargetUri sip:kmyer@litwareinc.com

Like Example 2, this example creates an announcement that plays an audio file when the number is reached. However, in this example in addition to the Identity, Name, and AudioFilePrompt parameters we also specify the TargetUri parameter. We pass this parameter the SIP URI of the user or phone to which the caller will be forwarded after the announcement has been played.

-------------------------- Example 4 ------------------------

Copy Code
New-CsAnnouncement -Identity ApplicationServer:redmond.litwareinc.com -Name "Busy"

In this example we don’t specify a prompt or a target URI, we include only an Identity and a Name. That means the caller will hear a busy signal when a call to an unassigned number associated with this announcement is connected.
