Abstract

본 호전환 방법은 2개의 음성코덱을 갖는 ISDN전화기에 있어서 교환기의 서비스를 이용하지 않고 간단하게 호전환을 하는 방법에 관한 것이다. 이를 위하여 본 방법은 2개의 음성코덱중 하나의 음성코덱에 접속되어 있는 송수화기를 통하여 통화중일때, 다른 음성코덱으로 호전환을 하기 위하여, 사용자로 부터 호전환 제어명령이 인가되면, 다른 음성코덱이 통화중인지를 체크하는 단계; 체크단계를 통하여 다른 음성코덱이 통화중이면, 호전환 제어명령을 무시하고 통화중단계로 천이하는 단계; 체크단계에서 다른 음성코덱이 통화중이 아니면, 다른 음성코덱에 부착되어 있는 송수화기에 링신호를 발생할수 있도록 제어하는 단계; 링신호 발생제어단계를 통해 링신호가 발생된 후, 소정시간동안 해당 송수화기에 접속되어 있는 음성코덱으로 부터 수신응답이 없으면, 통화중 단계로 천이하는 단계; 소정시간내에 음성코덱으로 부터 수신응답이 있으면, 통화로를 다른 음성코덱측으로 절체하는 단계를 포함하여 수행된다.This call transfer method relates to a simple call transfer method in an ISDN telephone having two voice codecs without using the service of an exchange. To this end, the method uses a handset connected to one of the two voice codecs to transfer to another voice codec when a call transfer control command is applied to the other voice codec. Checking if a call is in progress; If another voice codec is in the call through the checking step, ignoring the transfer control command and transitioning to the busy step; If the other voice codec is not busy in the checking step, controlling a ring signal to be generated in a handset attached to the other voice codec; After the ring signal is generated through the ring signal generation control step, if there is no response from the voice codec connected to the handset for a predetermined time, transitioning to a busy step; If there is a reception response from the voice codec within a predetermined time, the call path is transferred to another voice codec.
