Considerations for joining by phone as the host

  • If you have scheduled the meeting from a basic account, the meeting will timeout after forty-minutes with a thirty minute warning notification, if two or more participants join or you do not bind your phone and computer/mobile device session with the participant ID.
  • If you would like the meeting to last for unlimited duration, the meeting will need to be scheduled by a Licensed user, on a Pro or above account.
  • The number of phones that can connect to a Zoom meeting or webinar is determined by account type and add-on assigned to the user account.
