Abstract: A method of conferencing participant video data and audio data includes switching from a mesh-based conference to an MCU-based conference upon the occurrence of a trigger event. The mesh-based conference includes transmitting separate video and audio data streams between endpoints, and the MCU-based conference includes transmitting single video/audio data from endpoints to an MCU and combined video/audio data streams from the MCU to the endpoints.

Abstract: A system for sharing a communications session between multiple devices is disclosed. The system may receive a first request to establish the communications session from a first device associated with a user. The system may establish the communications session for the first device associated with the user in response to the first request. Additionally, the system may receive, from a second device associated with the first user, a second request to join the communications session. Furthermore, the system may join the second device to the communications session if the first request and the second request include a common identifier for the first user. Moreover, the system may transmit instructions for causing communications associated with the first device to be presented on a user interface of the second device during the communications session.
