Managing network regions in Skype for Business Server

Network regions are the network hubs or backbones used in the configuration of call admission control, E9-1-1, and media bypass. Use the following procedures to view, create, or modify network regions. For example, if you have already created network regions for one Voice feature, you do not need to create new network regions; other advanced Enterprise Voice features will use those same network regions. You may, however, need to modify an existing network region definition to apply feature-specific settings. For example, if you have created network regions for E9-1-1 (which do not require an associated central site) and you then deploy call admission control, you need to modify the network region definitions to specify a central site.

Use the procedures in this article to view network region information or create, modify, or delete network regions.

View network region information

A network region interconnects various parts of a network across multiple geographic areas. Every network region must be associated with a central site. The central site is the data center site on which the call admission control (CAC) bandwidth policy service is running. You can use Skype for Business Server Control Panel to view network regions. Network regions include settings that determine whether alternate paths through the Internet are allowed for audio and video connections. Use this topic to view existing network regions.

To view information about a network region with Skype for Business Server Control Panel

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or is assigned to the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Skype for Business Server Control Panel.

  3. In the left navigation bar, click Network Configuration, and then click Region.

  4. On the Region page, click the region you want to view.

    Note

    You can only view one region at a time.

  5. On the Edit menu, click Show details.

Viewing network region information by using Windows PowerShell cmdlets

You can view network region information by using Windows PowerShell and the Get-CsNetworkRegion cmdlet. You can run this cmdlet either from the Skype for Business Server Management Shell or from a remote session of Windows PowerShell.

To view network region information

  • To view information about all your network regions, type the following command in the Skype for Business Server Management Shell, and then press ENTER:

    Get-CsNetworkRegion
    

    That will return information similar to this:

    Identity         : Pacific Northwest
    Description      :
    BypassID         : 3b232b84-2c1d-4da2-8181-e9330bafebe9
    CentralSite      : Site:Redmond1
    BWAlternatePaths : {BWPolicyModality=Audio;AlternatePath=True, 
                       BWPolicyModality=Video;AlternatePath=True}
    NetworkRegionID  : Pacific Northwest
    

For more information, see the help topic for the Get-CsNetworkRegion cmdlet.

Create or modify network regions

A network region interconnects various parts of a network across multiple geographic areas. Every network region must be associated with a central site. The central site is the data center site on which the call admission control (CAC) bandwidth policy service is running. You can use the Skype for Business Server Control Panel to configure network regions. Network regions include settings that determine whether alternate paths through the Internet are allowed for audio and video connections. From the Skype for Business Server Control Panel, you can create, modify, or delete a network region. Use this topic to create and modify network regions.

To create a network region

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or is assigned to the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Skype for Business Server Control Panel.

  3. In the left navigation bar, click Network Configuration, and then click Region.

  4. On the Region page, click New.

  5. In the New Region page, type a value in the Name field. This value must be unique within your Skype for Business Server deployment.

  6. From the Central site drop-down list, select the central site for this network region.

  7. The Enable audio alternate path check box is checked by default. This field determines whether audio calls will be routed through an alternate path if adequate bandwidth does not exist in the primary path. Clear this check box only if you need to turn off the offload to the Internet. If any of your calls will be Internet calls, this check box must be checked, regardless of bandwidth settings.

  8. The Enable video alternate path check box is checked by default. This field determines whether video calls will be routed through an alternate path if adequate bandwidth does not exist in the primary path. Clear this check box only if you need to turn off the offload to the Internet. If any of your calls will be Internet calls, this check box must be checked, regardless of bandwidth settings.

  9. (Optional) Type a value in the Description field to provide more information about this region that cannot be expressed by the name alone.

  10. Click Commit.

The Associated sites table is not used for creating a network region. You associate a site with a region when you create or modify the site. For details, see Managing call admission control for sites.

To modify a network region
