Abstract
본 발명은 사설교환기에 관한 것으로 외부에서 국선을 통하여 사설교환기에 연결된 다른 국선을 이용하여 외부로 통화를 할 경우 중계접속을 요구하는 사용자의 고유번호와 중계접속에 대한 기능번호를 확인하여 사용자의 중계접속을 제한하며 중계접속되는 송수신 통화정보를 기록저장하여 불필요한 통화의 배제로 업무의 효율성이 향상된다.The present invention relates to a private exchange, when a user makes an external call using another trunk line connected to a private exchange through a trunk line from the outside, the user relays by checking the unique number of the user requesting the relay connection and a function number for the relay connection. It restricts access and records and transmits and receives relayed call information, thereby eliminating unnecessary calls and improving work efficiency.
본 발명의 사설교환기가 중계접속을 요구하는 DTMF 신호를 감지하면 DTMF 신호에서 사용자의 고유번호 및 중계접속에 대한 기능번호를 분석하는 단계와, 분석된 DTMF 신호가 중계접속 허락신호이면 중계접속을 요구한 사용자측에 발신음을 송출하고 국설교환기를 접속하는 단계와, 접속된 국선을 통한 통화정보를 저장하고 송수화 수단의 온 훅 여부를 감지하는 단계 및, 분석된 DTMF 신호가 중계접속 불허신호이면 그에 대한 톤 신호 또는 메세지를 중계접속을 요구한 단말기의 사용자측에 송출하는 단계를 포함한다.If the private exchange of the present invention detects a DTMF signal requesting a relay connection, analyzing the user's unique number and the function number for the relay connection from the DTMF signal, and if the analyzed DTMF signal is a relay connection permission signal, the relay connection is requested. Transmitting a dial tone to a user side and connecting a local exchange; storing call information through the connected trunk line and detecting whether the handset means is on-hook; and if the analyzed DTMF signal is a relay disallowed signal, Transmitting the tone signal or message to the user side of the terminal requesting the relay connection.
