It relates to a sender message registration method of a simple electronic exchange.

In a conventional private switching network, when a subscriber accommodated in the first switch is to call a subscriber accommodated in the second switch, the corresponding extension subscriber can answer if the corresponding extension subscriber is busy or busy. Since it is not possible to recognize when the time, there is an uncomfortable problem of calling repeatedly several times until the corresponding extension subscriber can respond.
