Part 7 – Enable a user for voice and voicemail services with Direct Routing

After you have assigned the correct licenses, the next step is to configure the user’s online phone settings. You’ll perform these steps using Teams PowerShell module.

To establish a remote PowerShell session with Teams, you first need to install the Teams PowerShell module.

 

After you install the module, you can establish a remote session with the following cmdlet:

Connect-MicrosoftTeams

You will typically enable Teams Phone functionality and assign a number available to you from your voice provider. As you enable Teams Phone for a user, voicemail will be automatically enabled at the same time.

To enable a user for Teams Phone functionality and assign a Microsoft Calling Plan phone number, use the following cmdlet:

Set-CsPhoneNumberAssignment -Identity "<User name>" -PhoneNumber "<phone number>" -PhoneNumberType CallingPlan

Supports E.164 format like +12065551234 and non-E.164 format like 12065551234. The phone number can’t have “tel:” prefixed.

Direct Routing numbers with extensions using the formats +1206555000;ext=1234 or 1206555000;ext=1234 are supported, but such phone numbers can’t be assigned to a resource account.

The example below shows how to assign Direct Routing number with a unique extension to the user:

Set-CsPhoneNumberAssignment -Identity "spencer.low@contoso.com" -PhoneNumber "+14255551234;ext=1001" -PhoneNumberType DirectRouting

The following cmdlet shows how to assign the same number with a different extension to another user:

Set-CsPhoneNumberAssignment -Identity "stacy.quinn@contoso.com" -PhoneNumber "+14255551234;ext=1002" -PhoneNumberType DirectRouting

If a user or resource account has a phone number set in Active Directory on-premises and synched into Microsoft 365, you can’t use Set-CsPhoneNumberAssignment to set the phone number. You will have to clear the phone number from the on-premises Active Directory and let that change sync into Microsoft 365 first. Then enable the user for enterprise voice services and voicemail using the following cmdlet:

Set-CsPhoneNumberAssignment -Identity "<User name>" -EnterpriseVoiceEnabled $true

Assign a voice routing policy
After configuring a phone number for the user and enabling the user for voicemail, you will then assign a voice routing policy to the user. This policy allows the user to dial out and receive calls by associating them with specific Direct Routing configuration:

Grant-CsOnlineVoiceRoutingPolicy -Identity "<User name>" -PolicyName "No Restrictions”
