Abstract
Abstract A reserved speech path forming method according to a first embodiment includes the steps of: determining whether or not another telephone within a parallel-connected telephone system is being used, enabling input of a reserved function key to reserve the speech path when another telephone within the parallel-connected telephone system is being used, providing a dial tone and enabling input of a reserved telephone number upon completion of use of the other telephone within the parallel-connected telephone system, dialing the reserved telephone number, and forming the reserved speech path. A reserved speech path forming method according to a second embodiment includes the steps of: determining whether or not another telephone within a parallel-connected telephone system is being used, enabling input of a reserved function key to reserve the speech path when another telephone within the parallel-connected telephone system is being used, storing a reserved telephone number input by a user, and automatically dialing the reserved telephone number and forming the reserved speech path upon completion of use of the other telephone within the parallel-connected telephone system.
