Abstract: A method and apparatus for enhancing the operation of a teleconferencing system, utilizes a programmed service computer (42) to drive a bridge (10) which has a plurality of ports (14) for establishing communication with a plurality of conferees (18, 20, ... 34). The bridge includes a microprocessor which responds to a plurality of commands, each requiring information in the form of plural constant information responses and plural variable information responses. The constant information responses involve the status and identification for a conference and conferees of that conference. The variable response information is specific to each conferee. This may include first and last name for the conferee, as well as the conferee's telephone number. The programming of the service computer supplies the information responses to the microprocessor in the appropriate order for achieving functions, such as the addition, removal and changing of status for conferees. The service computer can also communicate with terminals of the conferees so that data can be passed from one conferee to another.
