A multi-party call method provides connecting a multi-party call with a plurality of non-control terminals by a control terminal. Dual Tone Multi-Frequency (DTMF) signals are received from a part of the plurality of non-control terminals to which call termination commands are input by the control terminal, respectively. The received DTMF signals are recognized to check the part of the plurality of non-control terminals that have transmitted the DTMF signals; and the call states are displayed with the recognized part of the non-control terminals as a terminal state on a display screen.
