Teleconference scheduling and activity reporting method

A teleconference system that monitors the activity levels of one or more attendees of a teleconference and, based on that monitoring, provides information about attendees who are active participants and attendees who are passive listeners. The information includes evaluative feedback or a conference roster that is ordered based on the activity levels of the attendees, or both. Furthermore, the teleconference system takes into account that the potential invitees to a teleconference being scheduled can be different from one another in terms of their importance to a teleconference being scheduled, or in terms of the relevance of the teleconference to those invitees. The system is also able to consider the activity levels that are reported for a teleconference in progress when the system schedules a new teleconference.
