Question
You have a Microsoft Teams Phone deployment that contains a user named User1.
You need to use PowerShell to restrict User1 from using Teams to make international PSTN calls.
Which PowerShell cmdlet should you run?
Select only one answer.
A. Grant-CsCallingLineIdentity
B. Grant-CsDialoutPolicy
C. Grant-CsTeamsIpPhonePolicy
D. Grant-CsVoicePolicy
Answer
B. Grant-CsDialoutPolicy
Explanation
You can use the Grant-CsDialoutPolicy to restrict outbound calls on a per-user or per-tenant level.
The Grant-CsDialoutPolicy cmdlet is designed to manage outbound calling restrictions for both Audio Conferencing and PSTN calls in Microsoft Teams. Here’s why this is the correct choice:
Purpose of Grant-CsDialoutPolicy
- This cmdlet assigns a specific dial-out policy to a user, enabling you to control whether they can make international or domestic PSTN calls.
- For example, to block international PSTN calls, you can use a pre-defined policy like DialoutCPCDomesticPSTNDisabled or customize your own.
How It Works
The policy restricts outbound PSTN calls based on the assigned settings. For User1, you would execute:
Grant-CsDialoutPolicy -Identity "[email protected]" -PolicyName "DialoutCPCDomesticPSTNDisabled"
This ensures User1 can only make domestic PSTN calls while blocking international ones.
Comparison with Other Cmdlets
A. Grant-CsCallingLineIdentity: This cmdlet manages caller ID settings and does not control call restrictions.
C. Grant-CsTeamsIpPhonePolicy: This cmdlet applies policies for Teams IP phones, unrelated to PSTN call restrictions.
D. Grant-CsVoicePolicy: While this cmdlet manages voice routing and usage policies, it does not specifically handle dial-out restrictions like Grant-CsDialoutPolicy.
Flexibility and Predefined Policies
Microsoft provides several predefined dial-out policies for different scenarios (e.g., blocking all PSTN calls or allowing only domestic calls). These policies are easy to apply using Grant-CsDialoutPolicy.
Key Takeaways
- Use Grant-CsDialoutPolicy to restrict outbound PSTN calls for specific users in Microsoft Teams.
- Assign policies like DialoutCPCDomesticPSTNDisabled to block international calls while allowing domestic ones.
- This cmdlet is essential for managing outbound call restrictions in a granular and user-specific manner.
By mastering this cmdlet, you’ll be well-prepared for the MS-721 exam and real-world scenarios involving Microsoft Teams Phone deployments!
