发明名称 Conference call participation tracking
摘要 A method and apparatus for tracking participation in a conference call is disclosed. A conference tracker at a first location transmits a status signal to another conference tracker at a second location. The conference tracker at the second location receives the status signal and recognizes it as representative of an attribute of one or more of the parties at the first location. The attribute represented may be the identity of the first location, thereby informing the conference tracker at the second location that the first location remains connected to the conference call. In this manner, the conference tracker may inform a party of the number of connected locations or that a particular location has disconnected. The attribute represented may be the identity of the first location when a party at that location is speaking. In this manner, the conference tracker at the second location may thereby inform a listening party of the location of the speaking party. The attribute represented may be the identity of the speaking party, thereby enabling the conference tracker at the second location to determine which party is speaking. Status signals transmitted by each conference tracker may comprise audio pulses of unique frequencies, thereby enabling each conference tracker to determine the origin of each status signal. Consecutive pulses may be used to identify a particular status (e.g., connected or speaking).
