Provided are a system and method for controlling coupling between communication terminals for audio-video communication capable of performing the audio-video communication with a third external communication terminal by interworking a phone screen of a first communication terminal with a WiFi phone of a second communication terminal. The method includes the steps of: setting up, by a first communication terminal having a video communication function and a second communication terminal having an audio communication function, a coupling mode therebetween; and checking a coupling between the first communication terminal and the second communication terminal by means of a coupling identification code, and setting a speech path for transceiving video data to set up the coupling. Thereby, a plurality of WiFi phones are each coupled with one phone screen by predetermined rules, and any one of the WiFi phones can be used as an individual video phone. As such, a degree of application of the phone screen can be improved, and expensive devices mounted in the phone screen can be saved by the number of the coupled WiFi phones.
