Explanation:
We need to reconfigure all the meetings/conferences that require authentication or in other words, all meetings/
conferences that do not allow anonymous users.
We do this by running the Get-CsMeetingConfiguration cmdlet without any parameters to return a collection of
all the meeting configuration settings currently in use. That collection is then piped to the Where-Object cmdlet,
which selects only those settings where the AdmitAnonymousUsersByDefault property is equal to false.
Now that we have all the meetings/conferences that require authentication, we can use the SetCSMeetingConfiguration to reconfigure those meetings to enable the users to bypass the lobby by using the
PstnCallersBypassLobby = True parameter.https://technet.microsoft.com/en-us/library/gg425875.aspx
