This article describes how to enable Location-Based Routing for Direct Routing. Before you follow the steps in this article, make sure you've read Plan Location-Based Routing for Direct Routing and completed the steps in Configure network settings for Location-Based Routing.

After you deploy Direct Routing and set up network regions, sites, and subnets, you're ready to enable Location-Based Routing. To complete the steps in this article, you'll need some familiarity with PowerShell cmdlets. To learn more, see Teams PowerShell Overview

You have to enable Location-Based Routing for the following:

  • Users
  • Network sites
  • Gateway configurations
  • Calling policies

You can use the Teams admin center or PowerShell to enable Location-Based Routing.

Using the Microsoft Teams admin center

Enable Location-Based Routing for users

  1. Create a voice routing policy and assign PSTN usages to the policy. When you assign PSTN usages to a policy, make sure you do one of the following:

    • Use PSTN usages associated to voice routes that use a PSTN gateway local to the site.

    • Use PSTN usages associated to voice routes that use a PSTN gateway located in a region where Location-Based Routing restrictions aren't needed.

  2. Assign the voice routing policy to users who require routing restrictions to be enforced.

To learn more about how to create voice routing policies and assign them to users, see Manage voice routing policies in Microsoft Teams.

Enable Location-Based Routing for network sites

Enable Location-Based Routing for your sites that need to enforce routing restrictions. To do this, in the left navigation of the Microsoft Teams admin center, go to Locations > Network topology, select a network site, select Edit, and then turn on Location based routing.

To learn more, see Manage your network topology.

Enable Location-Based Routing for gateways

Enable Location-Based Routing to gateways that route calls to PSTN gateways that route calls to the PSTN, and associate the network site where the gateway is located.

  1. In the left navigation of the Teams admin center, go to Voice > Direct Routing, and then select the SBCs tab.

  2. Select the SBC, and then select Edit.

  3. Under Location based routing and media optimization, turn on Enable location based routing.

  4. Specify the gateway site ID, and then set the bypass mode.

  5. Select Save.

Enable Location-Based Routing for calling policies

To enforce Location-Based Routing for specific users, set up the user's calling policy to prevent PSTN toll bypass.

To do this, turn on the Prevent toll bypass and send calls through the PSTN setting in the calling policy.

  1. In the left navigation, go to Voice > Calling policies.
  2. Select the calling policy that you want to edit.
  3. Turn on Prevent toll bypass and send calls through the PSTN.
  4. Select Save.

Using PowerShell

Enable Location-Based Routing for users

  1. To set PSTN usages, use the Set-CsOnlinePstnUsage cmdlet. For multiple usages, separate each usage with a comma.

    Set-CsOnlinePstnUsage -Usage <usages>

    For example:

    Set-CsOnlinePstnUsage -Usage "Long Distance", "Local", "Internal"

  2. To create a voice routing policy to associate the user with the appropriate PSTN usage, use the New-CsOnlineVoiceRoutingPolicy cmdlet.

    New-CsOnlineVoiceRoutingPolicy -Identity <voice routing policy ID> -Description <voice routing policy name> -OnlinePstnUsages <usages>

    When you assign PSTN usages to a voice routing policy, make sure you do one of the following:

    • Use PSTN usages associated to voice routes that use a PSTN gateway local to the site.

    • Use PSTN usages associated to voice routes that use a PSTN gateway located in a region where Location-Based Routing restrictions aren't needed.

    The following example creates two new voice routing policies and assigns PSTN usages to them.

    New-CsOnlineVoiceRoutingPolicy -Identity "DelhiVoiceRoutingPolicy" -Description "Delhi voice routing policy" -OnlinePstnUsages "Long Distance" 
New-CsOnlineVoiceRoutingPolicy -Identity "HyderabadVoiceRoutingPolicy" -Description " Hyderabad voice routing policy" -OnlinePstnUsages "Long Distance", "Local", "Internal"

    The following table shows the voice routing policies defined in this example.

      Voice routing policy 1 Voice routing policy 2
    Online voice policy ID Delhi online voice routing policy Hyderabad online voice routing policy
    Online PSTN usages Long Distance Long Distance, Local, Internal

  3. To associate online voice routing policies to users who require routing restrictions to be enforced, use the Grant-CsOnlineVoiceRoutingPolicy cmdlet.

    Grant-CsOnlineVoiceRoutingPolicy -Identity <User> -Tenant <TenantId>

Enable Location-Based Routing for network sites

  1. To enable Location-Based Routing and associate voice routing policies to your network sites that need to enforce routing restrictions, use the Set-CsTenantNetworkSite cmdlet.

    Set-CsTenantNetworkSite -Identity <site ID> -EnableLocationBasedRouting <$true|$false>

    This example enables Location-Based Routing for the Delhi site and the Hyderabad site.

    Set-CsTenantNetworkSite -Identity "Delhi" -EnableLocationBasedRouting $true  
Set-CsTenantNetworkSite -Identity "Hyderabad" -EnableLocationBasedRouting $true

    The following table shows the sites enabled for Location-Based Routing in this example.

      Site 1 (Delhi) Site 2 (Hyderabad)
    Site name Site 1 (Delhi) Site 2 (Hyderabad)
    EnableLocationBasedRouting True True
    Subnets Subnet 1 (Delhi) Subnet 2 (Hyderabad)

Enable Location-Based Routing for gateways

  1. To create a gateway configuration for each gateway or network site, use the New-CsOnlinePSTNGateway cmdlet.

    New-CSOnlinePSTNGateway -Fqdn <FDQN registered for the SBC> -Identity <gateway configuration ID> -SipSignalingPort <listening port used> -Enabled $true

    If multiple gateways are associated with a system (for example, Gateway or PBX), modify each gateway to enable Location-Based Routing restrictions.

    The following example creates one gateway configuration for each gateway.

    New-CsOnlinePSTNGateway -Fqdn sbc.contoso.com -Enabled $true -SipSignalingPort 5067

    For more information, see Configure Direct Routing.

  2. To enable Location-Based Routing for your gateways that need to enforce routing restrictions, use the Set-CSOnlinePSTNGateway cmdlet.

    Enable Location-Based Routing to gateways that route calls to PSTN gateways that route calls to the PSTN, and associate the network site where the gateway is located.

    Set-CSOnlinePSTNGateway -Identity <gateway configuration ID> -GatewaySiteLbrEnabled $true -GatewaySiteID <site ID>

    The following example enables Location-Based Routing for each gateway that's associated to PSTN gateways in the Delhi and Hyderabad sites.

    Set-CSOnlinePSTNGateway -Identity sbc.contoso.com  -GatewaySiteLbrEnabled $true –GatewaySiteID "Delhi"
Set-CSOnlinePSTNGateway -Identity sbc1.contoso.com  -GatewaySiteLbrEnabled $true -GatewaySiteID "Hyderabad"

    Don't enable Location-Based Routing for gateways that don't route calls to the PSTN. However, you still have to associate the gateway to the network site where the system is located. This is because Location-Based Routing restrictions need to be enforced for PSTN calls reaching endpoints that are connected through this gateway. In this example, Location-Based Routing isn't enabled for each gateway that's associated to PBX systems in the Delhi and Hyderabad sites.

    Get-CSONlinePSTNGateway -Identity sbc.contoso.com 

Identity: sbc.contoso.com 
GatewaySiteLbrEnabled: $false 

Get-CSONlinePSTNGateway -Identity sbc2.contoso.com 

Identity: sbc2.contoso.com 
GatewaySiteLbrEnabled: $false

Enable Location-Based Routing for calling policies

To enforce Location-Based Routing for specific users, set up the users' voice policy to prevent PTSN toll bypass.

To enable Location-Based routing by preventing PSTN toll bypass, use the Grant-CsTeamsCallingPolicy cmdlet.

Grant-CsTeamsCallingPolicy -PolicyName <policy name> -id <user id>

In this example, we prevent PSTN toll bypass to User1's calling policies.

Grant-CsTeamsCallingPolicy –PolicyName "AllowCallingPreventTollBypass" -id "User1"
