Abstract: A cross-platform conferencing interface includes a graphical user interface (GUI) that displays multiple conferencing options, including a web conferencing option. Beginning at a home screen of the conferencing interface, a user can connect a web conference call through one of multiple web conference applications, or providers, in as few as two clicks. A first click can cause a web conference screen usable with multiple different conferencing applications to be displayed. The second click can initiate a call to a selected contact associated with the particular web conferencing application. The web conference screen acts as a front-end application program interface (API) for the web conferencing application or provider, but the call is connected using the application's resources. The interface can be implemented as a dedicated conferencing device that provides video conferencing, audio conferencing, web conferencing, and an interactive whiteboard.
