PURPOSE: A system for calling a wireless communication device is provided to reduce charge load by making telephone conversation be performed automatically through a wireless communication device at long telephone call using a general wire and a wireless telephone. CONSTITUTION: A telephone connecting part(11) is to connect a general wire, and wireless telephone and a telephone office line connecting part(10) is to connect a telephone office line. A direct current power part(21) supplies an operating voltage to a system. A receiver(12) enables a user to input a dial number when dialing through the wire and wireless telephone. A central processing unit(19) processes the dial number inputted through the receiver to perform a control function so as to speak over the telephone through a wireless communication device or a general telephone office line. The central processing unit senses an external telephone signal inputted to the general telephone when speaking over the wireless communication device and informs the user of the fact. The central processing unit judges the wireless communication device is connected with the system and informs the user the fact. A local loop switchover switch(14) senses that a user calls using the general telephone and switches into a general telephone network or a portable phone network according to judgement of the central processing unit. A speech network(16) separates a voice signal into a reception and transmission signals and transfers the voice signal from the wireless communication device to the general telephone.
