Abstract
Abstract A communication system comprises a plurality of speech communication terminals each having apparatus for inputting data representing a station. A call is issued in accordance with the data from the communication terminal, and the system receives call data representing a station which responds to the call. The data received by the system is compared with the data input from the speech communication terminal and display units of the speech communication units are controlled in accordance with the comparison result.
