After detecting a voice from the divided voice signal with a voice detecting algorithm, each frame energy value of the detected voice is calculated. The calculated each frame average energy value of the DT signal is compared with the calculated each frame energy value of the voice. As a result of comparison, if the calculated each frame energy value of the voice is similar to the calculated each frame average energy value of the DT signal, a communication circuit is forcibly shorted by being regarded as a DT.
