Communication connection establishing method, involves establishing audio connection between terminal and switching device by maintenance of video connection between another terminal and switching device based on detected instruction
The method involves initiating a video call of a participant terminal (1) to another participant terminal (11), and redirecting the video call to a switching device (3). The redirected video call is detected in the switching device, and a request for establishing an audio connection to the terminal (11) is output at the terminal (1) by the switching device. An audio connection between the terminal (11) and the switching device is established under maintenance of a video connection between the terminal (1) and the switching device, based on the detected instruction from the terminal (1). Independent claims are also included for the following: (1) a switching device for establishing a communication connection between two participant terminals (2) a system for establishing a communication connection between two participant terminals (3) a data storage medium that stores a computer program for executing a method of establishing a communication connection between two participant terminals.
