Abstract: Participants of a conference call dial in to or are invited to participate in a conference by a central conference calling center. Participant identification information is transmitted from the conference calling center to each of the participants. The participant identification information includes an unique identifier and an address associated with each of the participants of the conference call. Audio signals received at an electronic device are interrogated to identify the participant that originated the audio signals (the active participant). The audio signals and/or a graphical representation of the active participant is output in a predetermined manner based on the identification of the active participant that originated the audio signals.
