摘要：
The invention concerns placing an exploratory telephone call to a party, using a first telephone channel, in order to inquire whether the party wishes to hold a video conference. If the party does, the caller then actuates the invention, which establishes an initial video conference on a second data channel, without disrupting the existing telephone call. Then, after the video conference has been established, the exploratory telephone call is terminated, and the first channel is used to carry the video conference data, along with the second channel.
