PROBLEM TO BE SOLVED: To freely set the incoming sound of an information terminal at a reception side from a transmission side. SOLUTION: A calling signal for calling an information terminal at a reception side is transmitted, and desired voice data are transmitted so as to be related with the calling signal. At the time of receiving voice data related with the calling signal in addition to the calling signal at the information terminal at the reception side, the received voice data are reproduced instead of an incoming sound preliminarily stored in the information terminal at the reception side. Thus, the voice data are transmitted so as to be related with the calling signal from the information terminal at the transmission side, so that the incoming sound of the information terminal at the reception side can be turned into a desired voice.
