Dial-in conferencing provides a way for users to use a "regular" telephone (that is, a device on the public switched telephone network) to join the audio portion of a conference.
Dial-In Conferencing Cmdlets
If you do not want to allow dial-in conferencing you can disable this capability by using the Set-CsConferencingPolicy cmdlet and setting the EnableDialInConferencing property to False. By default, all users are allowed to host meetings that include dial-in conferencing.
