lecturer from the list of the connected participants.
Defined dial out participants and dial in participants are considered to be two separate participants
even if they have the same IP address/number. Therefore, if a defined dial-out participant is added to
the conference and the same participant then dials in (before the system dialed out to that
participant) the system creates a second participant in the Participants list and tries to call the dial-
out participant. If the dial-out participant was designated as the conference lecturer, the system will
not be able to replace that participant with the dial-in participant that is connected to the conference.
