PURPOSE: A mutual call processing device between switching centers is provided to confirm mutual calls by confirming an originated number and a called number, respectively, when a calling party and a called party simultaneously call each other, and to set a communication path with the called party based on the calling party, thereby immediately connecting mutual calls. CONSTITUTION: A local line unit(100) inputs/outputs call connection request signals and communication signals. A call setup unit(200) compares a called number of a called party with an originated number of a calling party if a communication line of the called party is occupied, and sets the communication path based on the calling party if the compared numbers are identical. A number translator(300) translates and outputs paths of a local number and a receiving number. A subscriber unit(400) monitors the occupied state of the communication path by a control signal while reporting the monitored results to the call setup unit(200), and transmits a communication signal in connection with the called party.
