Create or modify an unassigned number range in Skype for Business Server 2015

 

Topic Last Modified: 2015-08-17

Create, modify or delete unassigned number ranges for Announcement application in Skype for Business Server Enterprise Voice. This affects how calls to unassigned numbers are handled.

Skype for Business Server enables you to say what happens to incoming calls to phone numbers that are valid for your organization, but are not assigned to a user or a phone. To handle such calls, you set up an unassigned number table. You can use the table to route the calls to an Announcement application or to an Exchange UM server.

How you configure the unassigned number table depends on how you want to use it. You can configure the table with all the valid extensions for your organization, with only unassigned extensions, or with a combination of both types of numbers. The unassigned number table can include both assigned and unassigned numbers, but it is invoked only when a caller dials a number that is not currently assigned. If you include all the valid extensions in the unassigned number table, you can specify the action that occurs whenever someone leaves your organization, without needing to reconfigure the table. If you include unassigned extensions in the table, you can modify the action that occurs for specific numbers. For example, if you change the extension for your customer service desk, you can include the old customer service number in the table and then assign it to an announcement that provides the new number.

Use one of the following procedures to configure unassigned number ranges for the Announcement application.

importantImportant:
Before you configure the unassigned number table, your system must already either have Announcements defined or an Exchange Unified Messaging (UM) Auto Attendant set up.
tipTip:
When someone calls an unassigned number, Skype for Business Server searches the unassigned number table from top to bottom and uses the first matching range. Therefore, an action that you want to be performed as a last resort should be specified for the last range in the table.

  1. Log on to the computer as a member of the RTCUniversalServerAdmins group, or as a member of the CsVoiceAdministrator, CsServerAdministrator, or CsAdministrator role. For details, see Delegate setup permissions in Skype for Business Server 2015.

  2. Open a browser window, and then enter the Admin URL to open the Skype for Business Server Control Panel. For details about the different methods you can use to start Skype for Business Server Control Panel, see Open Skype for Business Server 2015 administrative tools.

  3. In the left navigation bar, click Voice Features, and then click Unassigned Number.

  4. On the Unassigned Number page, do one of the following:

    • To create a new number range, click New. In Name, type an identifying name for this range of numbers.

      noteNote:
      After you commit the new unassigned number range to the database, you cannot change this name.
    • To modify an existing number range, type all or part of the name of the number range in the search field. In the resulting list of number ranges, click the name you want, click Edit, and then click Show details.

  5. In the first Number range field, type the beginning number of the range, and in the second Number range field, type the ending number of the range.

    noteNote:
    • The beginning number of the range must be less than or equal to the ending number of the range.

    • If the beginning number of the range or the ending number of the range includes an extension number, both the beginning number and the ending number of the range must include an extension, and the extension number must be the same for both the beginning number and the ending number.

    • The number must match the regular expression (tel:)?(\+)?[1-9]\d{0,17}(;ext=[1-9]\d{0,9})?. This means the number may begin with the string tel: (if you don’t specify that string, it will be automatically added for you), a plus sign (+), and a digit 1 through 9. The phone number can be up to 17 digits and may be followed by an extension in the format ;ext= followed by the extension number.

  6. In Announcement service, do one of the following:

    • Click Announcement.

    • Click Exchange UM.

  7. If, in the previous step, you clicked Announcement, do the following:

    1. Under FQDN of destination server, click Select, click the service ID of the Application service that runs the Announcement application that will handle incoming calls to this range of unassigned numbers, and then click OK.

    2. In Announcement, click the announcement to be played for this range of unassigned numbers.

  8. If, in the previous step, you clicked Exchange UM, under Auto Attendant phone number, click Select, click the phone number to be used for this range of unassigned numbers, and then click OK.

  9. Click OK.

  10. On the Unassigned Number page, be sure that the unassigned number ranges are arranged in the order that you want. To change a range's position in the table, click one or more consecutive names in the list of ranges, and then click the up arrow or the down arrow.

    tipTip:
    Skype for Business Server searches the unassigned number table from top to bottom and uses the first range that matches the unassigned number. If you have overlapping ranges and one range specifies a last resort action, make sure that range is at the bottom of the list.
  11. When you have the unassigned number ranges in the order that you want, click Commit all.

  1. Log on to the computer where Skype for Business Server Management Shell is installed as a member of the RTCUniversalServerAdmins group or with the necessary user rights as described in Delegate setup permissions in Skype for Business Server 2015.

  2. Start the Skype for Business Server Management Shell: Click Start, click All Programs, click Skype for Business 2015, and then click Skype for Business Server Management Shell.

  3. Use New-CsUnassignedNumber to create a new unassigned number range. Use Set-CsUnassignedNumber to modify an existing unassigned number range.

    tipTip:
    If you have overlapping ranges and want the ranges to be applied in a specific order, include the Priority parameter. The range with the highest priority will be applied to the call.

    At the command line, do one of the following:

    • To create a number range for an Announcement service, run:

      New-CsUnassignedNumber -Identity <unique identifier for unassigned number range> -NumberRangeStart <first number in range> -NumberRangeEnd <last number in range> -AnnouncementName <announcement name> -AnnouncementService <FQDN or service ID of the Announcement service>
      
    • Or, to create a number range for Exchange UM Auto Attendant, run:

      New-CsUnassignedNumber -ExUmAutoAttendantPhoneNumber <phone number> -Identity <unique identifier for unassigned number range> -NumberRangeStart <first number in range> -NumberRangeEnd <last number in range>
      

    For example:

    New-CsUnassignedNumber -Identity "Unassigned range 1" -NumberRangeStart "+14255551000" -NumberRangeEnd "+14255551100" -AnnouncementName "Welcome Announcement" -AnnouncementService ApplicationServer:Redmond.contoso.com
    

    Or

    New-CsUnassignedNumber -ExUmAutoAttendantPhoneNumber "+12065551234" -Identity "Unassigned range 1" -NumberRangeStart "+14255551000" -NumberRangeEnd "+14255551100"
    

    The following example shows how to modify the numbers in an existing unassigned number range:

    Set-CsUnassignedNumber -Identity "Unassigned range 1" -NumberRangeStart "+14255551000" -NumberRangeEnd "+14255551900"
    

  1. Log on to the computer as a member of the RTCUniversalServerAdmins group, or as a member of the CsVoiceAdministrator, CsServerAdministrator, or CsAdministrator role. For details, see Delegate setup permissions in Skype for Business Server 2015.

  2. Open a browser window, and then enter the Admin URL to open the Skype for Business Server Control Panel. For details about the different methods you can use to start Skype for Business Server Control Panel, see Open Skype for Business Server 2015 administrative tools.

  3. In the left navigation bar, click Voice Features and then click Unassigned Number.

  4. On the Unassigned Number page, in the search field, type all or part of the name of the unassigned number range you want to delete.

  5. In the resulting list of number ranges, click the name, click Edit, and then click Delete.

  6. Click Commit all.

  1. Log on to the computer where Skype for Business Server Management Shell is installed as a member of the RTCUniversalServerAdmins group or with the necessary user rights as described in Delegate setup permissions in Skype for Business Server 2015.
