Systems and methods to accept information regarding audio communication
sessions (e.g., telephone calls) and, in response, initiate a
videoconference and/or data collaboration session via for example data
collaboration terminals associated with the audio terminals used for the
audio communication sessions. The videoconferences and/or data
collaboration sessions may be initiated using for example a voice call or
session, for example, by using DTMF, SMS, SVD etc. The information
required for the initiation of a videoconference or data collaboration
session may for example be transmitted between user terminals, a
centralized database may be used, or other methods may be used.
