Abstract

The invention provides a transfer service method for a telephone network by which, even if physical accommodation position information of a telephone set of a transfer destination is not registered in an electronic exchange connected by a wire or wireless to a telephone set on the originating side from which a telephone call is to be transferred, a transfer service to the telephone set of the transfer destination corresponding to a logic number can be enjoyed. The transfer service method comprises the steps of discriminating whether a telephone number by a telephone call originated from a telephone set is a telephone number whose physical accommodation position information is registered in an electronic exchange or a logic number whose physical accommodation position information is not registered in the electronic exchange, referring, when the telephone number is a logic number, to a logic number-transfer destination telephone number table set in advance in a memory of the electronic exchange and calling a telephone set of a transfer destination telephone number corresponding to the logic number, and performing a transfer service set in advance to the thus called telephone set.
