The following terms are used for the different roles people can have within a conference.
Participant – Any member of a conference.
Delegate – Any participant of a conference who is not a moderator.
Moderator – Moderators have extra functions. For example they can drop and mute other participants. Who is or can be a moderator depends on the conference type:
Ad-Hoc Conferences – Any internal participant is automatically also a moderator.
Personal Meet-Me Conferences – The conference owner is the only moderator.
System Conferences – A participant of a system conference can be become a moderator is either of 2 ways:
Specified internal users can be added to the conference’s moderator list. Those users are automatically moderators.
If the optional moderator PIN is set, any caller who enters that PIN joins the conference as a moderator. This allows external callers to be moderators (though without ability to drop/mute other participants).
Owner – Personal meet-me conferences are owned by the user with the same extension number as the conference ID. They are also automatically the conference’s only moderator.
