PURPOSE:To improve the calling operability by having only to operate one subscriber selection key to execute automatically a call to a 1st terminal equipment till a call to a 2nd terminal equipment while not limiting the number of communication opposite parties capable of automatic dialing. CONSTITUTION:If the connection of the 1st terminal equipment dialed at first by a terminal state discriminating means B is disabled of connection, after the line is opened automatically, the recalling is applied to the 2nd terminal equipment according to the dial information stored in the dial information memory A. Thus, the user stores the dial number information of each terminal equipment possessed by a desired communication opposite party in the dial information memory A corresponding to one subscriber selection key and has only to operate one subscriber selection key corresponding to the communication party thereby applying automatically the calling to the 1st terminal equipment and the recalling to the 2nd terminal equipment if the 1st terminal equipment is busy. Thus, the operation relating to the recalling is remarkably simplified.
