Your company has a Microsoft 365 subscription. A user named User5 cannot establish call from Microsoft Teams. You review the Microsoft Teams client…

For a user to make Public Switched Telephone Network (PSTN) calls from Microsoft Teams, two core components are required. First, the user must be assigned a "Microsoft Teams Phone" (formerly Phone System) license, which enables PBX capabilities in Microsoft 365. Second, the user's account must be enabled for Enterprise Voice. The absence of the dial pad in the Teams client is a direct symptom that one or both of these requirements have not been met for the specific user.

A. Modifying caller ID properties only changes the number displayed to the recipient; it does not enable the ability to make calls.
C. A SIP address is primarily used for federation and integration with SIP devices, not for enabling the core PSTN calling feature.
D. An app setup policy controls which apps are pinned to the Teams client's navigation bar, not the features available within the Calls app itself.
