Abstract

Abstract Methods of establishing multimedia conferences between a multimedia server and a plurality of endpoint devices. One or more of these endpoint devices are enhanced in that they include a memory adapted to store one or more telephone numbers, each telephone number corresponding to a respective endpoint device, and a user interface coupled to the memory for selecting a telephone number stored in the memory. The methods are performed in a substantially continuous manner, signifying that a third endpoint device is added to a preexisting conference between a first and a second endpoint device without substantially interrupting this preexisting conference. Therefore, a seamless multimedia conference is provided between the first and second enhanced endpoint devices even when a third endpoint device is added to the conference.
