Abstract: A method and system are described for establishing a telephone call between a caller terminal and a call recipient terminal, in which user-selected audio or video content is transmitted during the call in addition to any spoken audio or captured video data of the caller and call recipient. The user selected audio or video may for example be an audio music track, a video music track, or other audio or video content, such as live or prerecorded broadcast content. A call initiator can select a contact to call, and can select audio or video content to exchange on the call. The audio or video content can be played back during the call in a number of transmission modes, such as background in which the call data happens simultaneously in tandem with the audio- or video playback, or in switch mode, in which only one of the call or the audio or video data is playing at a time.
