PURPOSE: A call processing method in an operator position system(OPS) enables to perform a call process correctly between domestic and foreign subscriber calls in such a manner that the switching system displays a number information of an originating side on a monitor of the OPS, calls an incoming service subscriber call to be wanted, and re-calls the outgoing service subscriber call displayed on the monitor. CONSTITUTION: A domestic switching system(20) determines whether a call is transmitted to its own OPS controller(50) from a specific foreign switching system(10), and receives an information of an originating side call from the foreign switching system. The domestic switching system analyzes the grade of the originating side call, and consequentially provides call services according to the analyzed grade. Accordingly, outgoing/incoming service subscriber calls are connected correctly, thereby enhancing an operating reliability and efficiency of the OPS(60).
