CONSTITUTION:A central processing device 1 compares the time indicated by a timer 4 with a designated time in the interval of processing routines of the operation for a normal key telephone device; and if they coincide with each other, the central processing device 1 refers to system data stored in a random access memory 3 to transmit data of a tape recorder 7 or a voice synthesizing circuit 8 to an input/output interface 5. The central processing device 1 refers to system data stored in the memory 3 to confirm the transmission destination of a voice message and controls connections of a matrix switch 9 to transmit the voice message to an external speaker 12 or an extension telephone set. |
