Abstract:
A switching system comprising:switching means, connected to plural main-operator terminals and to plural training-target sub-operator terminals, for connecting a terminal in a public network and a main-operator terminal among the plural main-operator terminals and for making a condition in that information transmitted between two connected terminals including the terminal and the main-operator terminal is heard by a training-target sub-operator terminal among the plural training-target sub-operator terminals;main-operator terminal selection means, when a call of a predetermined type is received by the switching means, for selecting a responsible main-operator terminal among the plural main-operator terminals;first control means for controlling the switching means in a manner that the main-operator terminal selected by the main-operator terminal selection means receives the call;sub-operator terminal selection means, when the main operator terminal receives the call with the first control means, for selecting a responsible training-target sub-operator terminal among the plural training-target sub-operator terminals;second control means for controlling the switching means in order to make a condition in that information transmitted through the call received by the main-operator terminal is heard by the sub-operator terminal selected by the sub-operator terminal selection means;first information keeping means for keeping calling method information including at least one automatic calling method information showing that the training-target sub-operator terminal is called automatically and manual calling method information showing that the training-target sub-operator terminals called when instructed by the main-operator terminal; andsecond information keeping means for keeping selecting method information specifying a selecting method for the training-target sub-operator terminal among an equaled distribution selecting method, a priority selecting method and a registered terminal selecting method;wherein the sub-operator terminal selection means selects the responsible training-target sub-operator terminal based on the calling method information and the selecting method information.
