By default, with Microsoft® Office Communications Server 2007 R2, anyone with the conference calling number and your conference ID can join your conference. If you want to restrict who can join your dial-in conference, configure the following advanced Access options when scheduling the conference:

  • Open Authenticated. Allow only participants that are in your organization to join the meeting.
  • Closed Authenticated. Allow only invited participants within your organization to join the meeting.
