ABSTRACT:
The relationship between wire telephones and cordless terminals are registered in a memory of a PBX. At the time of calling, when a cordless terminal is taken from the wire telephone, the wire telephone transmits a call signal to the PBX and supplies the input telephone number of the called party to the PBX. The PBX executes a calling process between the PBX and the cordless terminal corresponding to the wire telephone through a cordless connecting device, thereby establishing a channel between the cordless terminal and the telephone terminal of the called party. When an incoming call is terminated, if the cordless terminal is on the wire telephone, the PBX calls the wire telephone. If the cordless terminal is lifted by the calling, the PBX executes an incoming call process between the PBX and the cordless terminal, thereby establishing a channel between the cordless terminal and the call party.
