PROBLEM TO BE SOLVED: To avoid useless calling not by continuously calling an opposite party unable to connect again but by continuously calling a group in one round to finish calling processing. SOLUTION: The telephone numbers of opposite parties unable to connect, i.e., uncommunicated telephone numbers among called telephone numbers are stored during continuous calling, when continuous calling to the group is performed in one round, the calling processing is finished, and when a user performs prescribed operation, the uncommunicated telephone numbers are read and the numbers can be continuously recalled. This telephone system has a calling history memory that can store a called telephone number history for finite numbers when dial calling is performed and does not store the telephone number of a calling destination in the calling history memory in the case of continuous calling. The telephone system is also provided with a voice outputting means for outputting the next calling destination by voice performing continuous calling.
