Ensure users dialing in can't bypass the lobby
Description
This policy setting controls if users who dial in by phone can join the meeting directly or must wait in the lobby. Admittance to the meeting from the lobby is authorized by the meeting organizer, co-organizer, or presenter of the meeting. For meetings that could contain sensitive information, it is best to allow the meeting organizer to vet anyone not directly from the organization.
