A method and system for administering calls on a voice network allows a user to selectively determine which calls will be accepted and assists the user in placing calls to other users on the network. The user may establish a list of users whose calls will be accepted and may also establish a list of users whose calls will not be accepted. The method and system may provide unwanted callers with an option to speak with the user for a fee. Users may establish “business card” headers, or profiles, which serve to identify the user to a called party. The user may also maintain profiles for received calls by using the “business card” header provided by the caller, or by inputting caller profiles. The method and system may also be used in conjunction with a scheduling system, such that calls amongst two or more users will be initiated at an agreed upon time.
