Abstract

A call selecting apparatus which comprises a signal receiver section for receiving dial signals in the form of dial pulse or DTMF; a main body processor for effecting call connection processing based on the transmitted digit codes which were received; and a received digit codes accumulating section for accumulating the digit codes received based on the dial signals received by the signal receiver section and which is provided as a peripheral device of the main body processor. The apparatus includes a digits number decision/call determination section for executing the decision how many digits codes should be accumulated in the received digit codes accumulating section as an accomplished destination telephone number, as well asdetermining whether the received digit codes correspond to the destination telephone number of a specific call or not. The digits number decision/call determination section is arranged as a peripheral device of the main body processor. The main body processor is arranged so that the result of the received digit codes and that of the determination are collectively inputted thereto. Particularly, the main body processor effects preferentially the connection processing as the digit codes received in the case where the digit codes received correspond to the destination in case of originating call congestion. The result is connection processing can positively be carried out in even an originating call congestion case.
