MULTIFUNCTIONAL TELEPHONE SET

摘要

PURPOSE: A multifunctional telephone set is provided to offer an ACR(Automatic Call Routing) service to connect overseas and long-distance calls automatically. CONSTITUTION: A memory part(100) stores a program to add an output appointment number to an inputted telephone. A main control part(110), if a program changing intrinsic number is inputted, interrupts signal transmission or executes the control to correct the program data of the memory part(100). An ARS detection part(120) detects the frequency of an ARS voice signal so that a caller can execute processing by a prepaid card or a post payment card according to the control signals of the main control part(110). The DTMF receiving part(130) detects a DTMF signal from the voice signal detected from the ARS detection part(120). The voice switching part(140) receives the DTMF signal detected from the DTMF receiving part(130) and executes switching. A DTMF generation part(150) receives the code data, related to button data by the dialing of the caller, from the main control part(100) and outputs the DTMF signal corresponding to the code data. A routing control part(160) controls the path of a voice signal inputted from a rectification bridge connected to tip/ring terminals.
