Start an Audio Conference over the phone without a PIN in Microsoft Teams
It might be frustrating for users who dial in to a meeting to be held in the meeting's lobby listening to music because the Microsoft Teams meeting organizer hasn't started the meeting.
If a meeting organizer calls in to the meeting, by default, a PIN is required to start a meeting. You can set it up so that anyone can dial in to a meeting and not be prompted for a PIN to start the meeting. You can use the admin center to enable or disable this setting for a single user.
A PIN isn't required for the meeting organizer if someone has started the meeting from the Microsoft Teams app. A PIN is only required when a meeting organizer joins their meeting over a phone. The PIN for meetings is sent to the audio user when they are assigned the Audio Conferencing license and are enabled for Audio Conferencing. See Send an email to a user with their Audio Conferencing information and Emails that are automatically sent to users when their Audio Conferencing settings change.
We are frequently updating how you can manage features, so the steps here might be a little different from what you see.

If anonymous access, or not requiring a PIN to start a meeting, is disabled:
If the meeting hasn't started (there's no one in the meeting yet): A caller will be prompted if he's the organizer; if he says yes, he'll be prompted for his PIN, and after he inputs the PIN, the meeting will start and the user will join the meeting.
If the meeting already started (someone else is already in the meeting): A caller won't be prompted if he's the organizer and he'll never be prompted for the PIN; the meeting is already started, and the caller will join it.
If anonymous access, or not requiring a PIN to start a meeting, is enabled:
If the meeting hasn't started (there's no one in the meeting yet): A caller won't be prompted if she's the organizer, and she'll never be prompted for the PIN. Because the setting of the organizer is set to off, the meeting will start and the anonymous callers will join the meeting.
If the meeting already started (someone else is already in the meeting): A caller won't be prompted if she's the organizer, and she'll never be prompted for the PIN,;the meeting is already started, and the caller will join it.
