Abstract

An incoming call controller for preferentially connecting a waiting calling subscriber, who had previously made more unsuccessful call attempts than any other waiting calling subscriber, to a called subscriber. The unsuccessful call attempts result in the calling subscriber receiving a busy signal. Call registering apparatus within the incoming call controller store identification data of each particular calling subscriber or calling terminal receiving a busy signal. After identification data is registered, the call register indicates future unsuccessful call attempts by incrementing a data field comprising the number of unsuccessful call attempts of the particular calling subscriber or calling terminal. A call manager within the incoming call controller identifies the calling subscriber registered as having previously made the most unsuccessful call attempts. When a line to the called subscriber becomes available, the calling subscriber or calling terminal identified by the call manager is connected to the called subscriber and the data field associated with the number of unsuccessful call attempts by the calling subscriber is reset.
