Abstract
A voice storage device monitors wireless signals from a plurality of fixed terminals and a plurality of mobile terminals, which are connected to a main unit. When a channel establishment signal is generated by one mobile terminal, the voice storage device detects this signal, and prepares for recording the contents of a speech communication. Subsequently, the fixed terminal generates a channel assignment signal. Thereafter, the voice storage device detects a call setup signal (an ID signal and control information) exchanged between the mobile and fixed terminals, and waits for detection of a response signal which is generated by the mobile terminal and indicates that the call is answered. Upon detection of the response signal, the voice storage device starts a storage operation of voice data at a corresponding one of different storage positions in units of mobile terminals, which position is specified by the call setup signal.
