MS-700 Configure and Manage a Teams Environment Practice Question
You are a Teams administrator for a multinational corporation. The company has recently deployed Microsoft Teams and wants to ensure that all users can make and receive calls using Teams. You need to assign phone numbers to users. Which PowerShell cmdlet should you use to assign a phone number to a user?
⚠ Common exam trap
The trap here is assuming that legacy Skype for Business cmdlets like Set-CsUser are still used for Teams phone number assignment, when the newer Set-CsPhoneNumberAssignment is required.

✓
Set-CsPhoneNumberAssignment
The Set-CsPhoneNumberAssignment cmdlet is specifically designed to assign, update, or remove phone numbers for users in Microsoft Teams. It supports various phone number types and is the current recommended method for phone number management. Other cmdlets either serve different purposes or are not valid for this task. Using the correct cmdlet ensures successful phone number assignment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set-CsUser
Why it's wrong here
Set-CsUser is used to modify properties of a user in Skype for Business Online, such as enabling Enterprise Voice or setting the line URI. However, for Teams phone number assignment, the recommended cmdlet is Set-CsPhoneNumberAssignment. Set-CsUser is deprecated for Teams phone management and does not provide the same functionality for assigning phone numbers in Teams.
- ✗
Grant-CsOnlineVoiceRoutingPolicy
Why it's wrong here
Grant-CsOnlineVoiceRoutingPolicy assigns a voice routing policy to a user, which determines how calls are routed. It does not assign a phone number. This cmdlet is used after phone numbers are assigned to control call routing. It is not the correct cmdlet for assigning a phone number to a user.
- ✗
Set-CsOnlineVoiceUser
Why it's wrong here
Set-CsOnlineVoiceUser is not a valid cmdlet in the MicrosoftTeams PowerShell module. The correct cmdlet for managing voice settings is Set-CsPhoneNumberAssignment. Using an incorrect cmdlet will result in an error and will not assign a phone number. This option is a distractor and does not exist.
- ✓
Set-CsPhoneNumberAssignment
Why this is correct
Set-CsPhoneNumberAssignment is the correct cmdlet to assign, update, or remove a phone number for a user in Microsoft Teams. It is part of the MicrosoftTeams PowerShell module and is used to manage phone number assignments for Direct Routing, Calling Plans, and Operator Connect. This cmdlet directly fulfills the requirement to assign a phone number to a user.
