In one example, a method for a conference bridge failover in a conference call system may include determining that a first conference bridge with a connection for a participant telephone has failed. The method may also include determining whether one or more conference bridge have resources to manage the connection for the participant telephone of the first conference bridge and assigning the connection for the participant telephone to the one or more conference bridge in response to the determination.

Conference call resource assignment for failover

A conference call solution with one or more conference server, one or more conference bridge and one or more media mixer. A conference server is chosen as the conference bridge for the conference call using various optimization techniques. A media mixer for the conference call may also be chosen using various optimization techniques. The media mixer mixes media data from one or more conference bridge. If a conference bridge or the media mixer fails, the system recovers from the failure with minimal interruption to the users.

Distributed audio conferencing architecture with optimum resource utilization and seamless scalability

A conference call system with a plurality of endpoints, a participant control server, a conference bridge and a switch is described. A first endpoint transmits conference data to the participant control server. The participant control server transmits the conference data to the other endpoints. In response to requests from the endpoint, the participant control server transmits recorded conference data for video, audio and web sessions that are individually controllable to pause, fast-forward and rewind the conference data. The participant control server establishes secondary connections for the endpoints including a ghost hold and a sidebar.
