Teams Conference Phone License with PSTN and One-Touch Join

Community Votes
100% of anonymous learners picked answer E. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
This question tests the licensing distinction between shared Teams phones and dedicated Teams Rooms systems; the common trap is assuming that one-touch join or PSTN calling implies a Teams Rooms Pro license.
Teams conference phones that support PSTN calls and one-touch join require a Microsoft Teams Shared Device license, not a user license like Microsoft 365 E5. This page establishes that the correct answer is B, contrasting it with the often-confused Teams Rooms Pro license.
The most common wrong answer is Teams Rooms Pro (E), chosen because it also includes Teams Phone and meeting join, but that license applies to meeting room systems, not conference phones.

Expert Analysis
Why the Answer Is Correct
The device in question is a Microsoft Teams conference phone, which belongs to the Teams phones device category. Microsoft licensing guidance requires a Microsoft Teams Shared Devices license for Teams phones, including conference phones, to enable PSTN calling through Operator Connect and one-touch join for Teams calendar meetings. This license is assigned to a resource account for the shared device, not to a user, and it includes the necessary Teams Phone capabilities. Therefore, option B is the correct license.
Why the Other Options Are Wrong
Options A, C, and D are all user-based licenses (Microsoft 365 E5, Business Standard, E3) and cannot be assigned to a shared device like a conference phone. Option E, Teams Rooms Pro, is designed for dedicated Microsoft Teams Rooms systems (Windows or Android) that include a compute unit and touch console, not for standalone conference phones. While Teams Rooms Pro also includes Teams Phone and meeting join, it is scoped to meeting room devices, making it the wrong choice for this scenario.
Community Comment Notes
The community votes overwhelmingly favored option E, with comments like "teams room pro is the correct answer" from kaycee_a reflecting a common misconception. HOzwei linked to a Tech Community blog on deploying Teams phone devices, but that blog actually supports the Shared Device license for phones. Aboed mentioned that an "audio-conferencing device in a small meeting room" needs Teams Rooms Pro, but that describes a Teams Rooms system, not a standalone conference phone. These comments highlight the importance of distinguishing device categories when choosing licenses.

Exam Strategy
When you see 'conference phone,' think 'Teams phone' and choose Microsoft Teams Shared Device. If the scenario says 'Teams Rooms' or 'meeting room system,' then Teams Rooms Pro is the correct license.
