Assign a phone number for user using Direct Routing

Direct Routing Number Assignment in Microsoft Teams

The Direct Routing option not appearing in the Teams admin center dropdown is expected behavior and does not indicate a configuration issue.

The Teams admin center only displays number types available within your Microsoft managed phone number inventory. Direct Routing numbers are managed outside Microsoft, so they do not appear in this dropdown regardless of the licenses assigned to the user.

Direct Routing numbers should therefore be assigned through PowerShell.

1. Assign the Direct Routing Number

Use the following command:

The phone number must use E.164 format, including the plus sign and country code.

After assigning the number, allow a few minutes for the change to propagate, then refresh the Teams admin center. The number should appear against the user once synchronization is complete.

1. Regarding the Alternative PowerShell Method

Some older guidance recommends using:

Set-CsUser -LineUri

This method is outdated for Teams phone number assignment.

Microsoft now recommends using:

Set-CsPhoneNumberAssignment

The parameter:

-PhoneSystemRoutingPolicyName

is also not a valid parameter for Set-CsUser in the current Teams PowerShell module and should not be used for this configuration.

1. Licensing Requirements

A Microsoft Calling Plan license is not required when using Direct Routing.

The user requires:

1. Microsoft Teams Phone, previously known as Phone System
2. An Online Voice Routing Policy containing the appropriate PSTN usages and routes for the Direct Routing trunk

A Calling Plan license is only required when using Microsoft provided phone numbers.

If the environment uses Direct Routing exclusively, the Calling Plan license can be removed. Keeping it assigned will not prevent Direct Routing from working, but it may influence what options are displayed within the Teams admin center.

1. Additional Checks

Before assigning the number, confirm that Enterprise Voice is enabled for the user:

Get-CsOnlineUser -Identity email address removed for privacy reasons | Select EnterpriseVoiceEnabled

Also confirm that the user's Online Voice Routing Policy contains the correct PSTN usages and routes associated with the Direct Routing trunk.

The phone number may still assign successfully if these settings are missing, but inbound or outbound calling may not route correctly until the voice routing configuration is complete.

Hi VoipJedi,

To enable users for Direct Routing, you must have the following:

• A Direct Routing trunk configured in Teams.
• The appropriate licensing for your users, including the Phone System license and a calling plan.

Once you have these things in place, you can enable users for Direct Routing by following these steps:

1. Go to the Microsoft Teams admin center.
2. Click Users > Manage users.
3. Select the user or users that you want to enable for Direct Routing.
4. Under Account, click Edit.
5. Under Assign phone number, select Enable users for Direct Routing.
6. Click Apply.

You can also do that with PowerShell:

To enable users for Direct Routing in Teams using PowerShell, follow these steps:

1. Open PowerShell as an administrator.
2. Import the Teams PowerShell module:

Import-Module MicrosoftTeams​

1. Connect to Teams:

Connect-MicrosoftTeams -Credential $credential​

where $credential is a variable that stores your Teams administrator credentials.

1. Get a list of all users that are enabled for Phone System:

Get-CsOnlineUser | Where-Object { $_.EnterpriseVoiceEnabled -eq $true }​

1. Enable the users for Direct Routing:

Set-CsUser -Identity "<User name>" -PhoneSystemRoutingPolicyName "DirectRouting"​

where <User name> is the name of the user that you want to enable for Direct Routing.

1. Assign a phone number to the user:

Set-CsUser -Identity "<User name>" -LineUri "<Phone number>"​

where <Phone number> is the phone number that you want to assign to the user.

1. Disconnect from Teams:

Disconnect-MicrosoftTeams​

For example, to enable a user named John Doe for Direct Routing and assign him the phone number 123-456-7890, you would use the following PowerShell commands:

Import-Module MicrosoftTeams
Connect-MicrosoftTeams -Credential $credential

# Get a list of all users that are enabled for Phone System
$users = Get-CsOnlineUser | Where-Object { $_.EnterpriseVoiceEnabled -eq $true }

# Enable John Doe for Direct Routing
Set-CsUser -Identity "John Doe" -PhoneSystemRoutingPolicyName "DirectRouting"

# Assign the phone number 123-456-7890 to John Doe
Set-CsUser -Identity "John Doe" -LineUri "123-456-7890"

Disconnect-MicrosoftTeams

You can also use PowerShell to enable multiple users for Direct Routing at once. For example, to enable all users that are enabled for Phone System for Direct Routing, you would use the following PowerShell command:

Get-CsOnlineUser | Where-Object { $_.EnterpriseVoiceEnabled -eq $true } | Set-CsUser -PhoneSystemRoutingPolicyName "DirectRouting"

Once you have enabled users for Direct Routing and assigned them phone numbers, they will be able to make and receive calls using their Direct Routing trunk.
