Audio Conferencing FAQ

How does a user schedule and start a meeting when all attendees will be using a phone to dial-in?

Scheduling a meeting that will be joined by all attendees using a phone to dial-in is not different from scheduling a regular online meeting. However, there are two ways to start a meeting on which all of the participants use a phone to dial-in:
Option #1: By default, if the meeting organizer and all participants are joining a meeting using a phone, the meeting organizer needs to input his or her Audio Conferencing PIN to start it. Callers get asked if they wish to authenticate as the organizer of a given meeting when they dial the phone number of an online meeting. All participants that join the meeting via dial-in before the organizer starts will be placed in the lobby and will listen to music on hold. For Microsoft Teams meetings, the participants will join the meeting according to the value of the automatically admit people setting in the organizer's meeting policy.
Option #2: If the “Allow unauthenticated callers to be the first people in a meeting“ setting (disabled by default) is enabled for a given organizer, then all meetings scheduled by that user will be able to be started without having the organizer input his or her Audio Conferencing PIN. When this setting is enabled, the meeting will start as soon as the first participant joins it via a dial-in phone number and he or she will not be put in the lobby.


Who can attend an Audio Conferencing meeting? And who can I hear?

Anyone who has the dial-in number and conference ID can join a Microsoft Teams meeting, unless the meeting organizer has locked the meeting.
Whether you're calling in using a phone or the Microsoft Teams app, you'll be able to hear everyone else on the call, and they can hear you. The meeting organizer has the ability to "mute" meeting attendees if they don't want to hear them.


What in-meeting dial-pad commands are supported?

*6 (mute/unmute yourself)
*1 (description of dial-pad commands available)


How many total phone participants can I have in meetings?

Audio Conferencing allows up to 250 phone attendees.
