Abstract

둘 이상의 통화 선로를 갖는 다기능 전화기의 통화 방법에 있어서 사용자의 부재시에 수신되는 통화요구에 응답하여 지정된 외부의 다른 전화기를 통해 통화할 수 있는 우회 통화 방법이 개시되고 있다. 본 발명은 다수의 통화 회선을 갖는 다기능 전화기의 통화 방법에 있어서, 제1통화 선로를 통한 통화 요구 신호 수신시 제2통화 선로를 통해 사용자가 지정한 특정 전화기와 통화로를 형성하고 상기 제1통화 선로와 제2통화 선로를 접속시켜 우회 통화로를 형성하는 우회 통화 방법에 관한 것이다. 본 발명에 따르면 내선통화 선로를 통해 통화 요구 신호가 수신되면 국선 통화 선로를 통해 미리 지정한 전화번호를 갖는 전화기와 통화로를 형성하고 내선 통화 선로와 국선 통화 선로를 접속시켜, 사용자의 부재시에도 이동장소의 전화기를 통해 내선호출자와 우회 통화할 수 있다.In a call method of a multifunction telephone having two or more call lines, a bypass call method is disclosed that enables a user to make a call through another external telephone designated in response to a call request received in the absence of a user. The present invention provides a call method of a multifunctional telephone having a plurality of call lines, and upon receiving a call request signal through a first call line, forms a call path with a specific phone designated by a user through a second call line, and the first call line And a bypass call method for connecting a second call line to form a bypass call path. According to the present invention, when a call request signal is received through an internal call line, a telephone line and a call line having a predetermined telephone number are formed through a CO line, and the call line is connected to an extension line and a CO line, so that the user can move even when the user is absent. You can make a bypass call with an extension caller through your phone.

Claims

A call method of a multifunction telephone having at least two call lines and comprising connecting means for selectively connecting the call lines, wherein the central processing unit receives a key input signal from a key input unit and correspondingly enters a recording mode and a bypass call mode. A mode selection process for selecting and designating, a recording process of receiving, by the central processing unit, a key input signal of a telephone number to be connected to a bypass call from a key input unit, converting the signal into telephone number data, and recording the signal into a memory; The processor receives the call request signal from the first call line through the ring detection unit when designating the bypass call mode, reads the telephone number data from the memory, and transmits the corresponding DTMF signal to the second call line, and sends the DTMF signal. Search the incoming call status of the first call line through the internal connection circuit It consists of a bypass call process that connects the second call line and cuts off the connection between the first call line and the second call line through the internal connection circuit at the end of the call, and sends a call impossible signal to the first call line when the call is not received. Bypass calling method characterized in that.
