MS-700 Manage Meetings and Calling Practice Question
A user reports that they cannot join a scheduled Teams meeting by dialing in with a phone. The meeting invitation does not show any dial-in number. The administrator confirms that the user has an Audio Conferencing license and the bridge is configured. What is the most likely cause?
⚠ Common exam trap
The trap here is thinking that an Audio Conferencing license alone guarantees dial-in numbers, but the meeting policy setting must also be enabled.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user's meeting policy has Allow PSTN dial-in disabled.
The most likely cause is that the meeting policy assigned to the user has Allow PSTN dial-in disabled. Even with an Audio Conferencing license, this policy setting controls whether dial-in information appears in meeting invitations. Enabling it will add the dial-in numbers. Other options like Enterprise Voice, dial plans, or personal phone numbers do not affect dial-in inclusion.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The user's meeting policy has Allow PSTN dial-in disabled.
Why this is correct
If the Allow PSTN dial-in setting is disabled in the meeting policy, meeting invitations will not include dial-in numbers even if the user is licensed for Audio Conferencing. This directly explains the missing dial-in information. Enabling this setting would resolve the issue, making it the most likely cause.
- ✗
The user has not been assigned a phone number.
Why it's wrong here
A user does not need a personal phone number to have dial-in numbers in their meetings. Audio Conferencing provides a shared bridge with dial-in numbers. Assigning a phone number to the user is separate and not required for meeting dial-in. Thus, this is not the cause.
- ✗
The user's dial plan does not include the conferencing bridge number.
Why it's wrong here
Dial plans are used for number normalization and routing of outbound calls, not for including dial-in numbers in meeting invitations. The conferencing bridge number is automatically included based on the meeting policy. Dial plans do not affect the presence of dial-in information in invitations.
- ✗
The user is not enabled for Enterprise Voice.
Why it's wrong here
Enterprise Voice is for making and receiving calls in Teams, not for audio conferencing dial-in. Audio Conferencing is a separate service that provides dial-in numbers. A user can have Audio Conferencing without Enterprise Voice. Therefore, this is not the cause of the missing dial-in number.
