Providing high availability multi-way conferencing. Separate signaling and media components may be provided within an MCU or among a cluster of MCUs. A signaling server may control signaling aspects of a conference while a media server may provide media support for the conference. In the event of media server failure, the signaling server may assign a new media server to provide media support for the conference. A backup signaling server may also monitor the signaling server and may provide signaling support for the conference in the event of signaling server failure.

Architecture for high availability conferencing

A videoconference may be initiated between a plurality of endpoints. At least one of the endpoints may be coupled to a recording server, which may be configured to record the videoconference. A configuration may be selected (e.g., automatically or manually) for performing the recording. The endpoint (e.g., acting as an MCU) may transmit information to endpoints and may transmit recording information to the recording server. The recording information may be different from the videoconference information. For example, it may be in a 'streaming friendly' format, at a different bit rate, encoded differently, have different inputs, etc. The manner in which the videoconference is stored and/or recorded may be based on the selected configuration. Clients may be configured to receive and display the videoconference from the recording server and may be configured to change the provided layout to different layouts, e.g., based on user input.

Selective audio combination for a conference. The conference may be initiated between a plurality of participants at respective participant locations. The conference may be performed using a plurality of conferencing endpoints at each of the participant locations. Audio may be received from each of the plurality of conferencing endpoints. Audio level information may also be received from each of the plurality of conferencing endpoints. The audio may be combined from a plural subset of the plurality of conferencing endpoints to produce conference audio. The plural subset is less than all of the plurality of conferencing endpoints. The audio may be combined based on the audio level information. The conference audio may be provided to the plurality of conferencing endpoints.
