Zusammenfassung:PROBLEM TO BE SOLVED: To appropriately transfer a call on the line to a transfer destination with the initiative by the transfer destination.SOLUTION: In a call transfer system, an extension telephone B of a transfer destination transmits a hold/transfer request to a main device 1 to transfer a call between a line 3 established by the main device 1 and an extension telephone A of a transfer source to the extension telephone B itself. The main device 1 stores preset transferable conditions, records call information on the call and, when the hold/transfer request is received from the extension telephone B of the transfer destination, determines whether or not to transfer the call based on whether the call information on the call related to the extension telephone B of the transfer destination meets the transferable conditions. When the call is determined as transferable, the main device switches the destination of the line 3 from the extension telephone A of the transfer source to the extension telephone B of the transfer destination.
