Abstract
An automatic method for adding an additional data stream, such as auxiliary teleconference data, to an existing media connection between two endpoints, such as a teleconference between teleconferencing systems. A first endpoint identifies the availability of a second data stream to a second endpoint via a first message which references the existing media connection. The first endpoint notifies the second endpoint of the desire to connect via a second message. The second endpoint notifies the first endpoint of confirmation to connect via a third message. The first and the second endpoint then establish communication wherein the additional data stream is associated in a first endpoint and the second endpoint with the existing media connection.
