You plan to implement a pilot project on Phone System for 100 users. The pilot project will use a Microsoft Calling Plan. You need to ensure that the users can establish calls to the PSTN. Which cmdlets should you run?

To enable users for PSTN calling with a Microsoft Calling Plan, three main configuration steps are required via PowerShell. First, assign the necessary licenses (Phone System and a Calling Plan) using a licensing cmdlet like Set-AzureADUserLicense. Second, enable the user for Enterprise Voice, which is done using Set-CSUser -EnterpriseVoiceEnabled $true. Third, assign a phone number to the user from Microsoft's number inventory using Set-CsOnlineVoiceUser. This combination of cmdlets fulfills all the requirements to make a user PSTN-capable with a Calling Plan.

A. This option is missing Set-CsOnlineVoiceUser, which is essential for assigning the actual phone number to the user.
B. Grant-CsOnlineVoiceRoutingPolicy is used for configuring Direct Routing, not Microsoft Calling Plans, making this option incorrect for the scenario.
C. This option incorrectly includes Grant-CsOnlineVoiceRoutingPolicy, which is for Direct Routing, and omits the necessary licensing cmdlet.
