The present disclosure proposes a method capable of, when a user simultaneously selects several PTT channels even in an apparatus not supporting a display, identifying the several PTT channels using alarm sounds for the PTT channels to transmit voices and distinguishing through which PTT channel a received voice is received, and a PTT terminal supporting the same. The present disclosure provides a push-to-talk (PTT) communication method, comprising: a step of connecting multiple PTT channels for communications between terminals; a step of storing history information representing received time of voice data through the multiple PTT channels; a step of selecting a PTT channel on the basis of the history information with respect to the multiple PTT channels, if an input of a PTT button is sensed; and a step of transmitting voice data to the selected PTT channel.
