Abstract: A conferencing system (10) includes a mixer (12) operable to process audio and video packets received from a plurality of endpoint devices (15, 16, 17, 19, 21 ), and to transmit a processed audio / video stream back to the endpoint devices (15, 16, 17, 19, 21). The endpoint devices (15, 16, 17, 19, 21) may be configured with an associated video camera (18, 20, 22). A server (11) connects with the mixer (12) and the endpoint devices (15, 16, 17, 19, 21). The server (11) is operable to send a first transmission to a first endpoint device (17) that causes the first endpoint device (17) to stop transmitting video packets to the mixer (12). The server (11) is further operable to send a second transmission to a second endpoint device (21 ) that causes the second endpoint device (21) to start transmitting video packets to the mixer.
Abstract translation: 会议系统（10）包括可操作以处理从多个端点设备（15,16,17,19,21）接收的音频和视频分组的混合器（12），并且将经处理的音频/视频流发送回 端点设备（15,16,17,19,21）。 端点设备（15,16,17,19,21）可以配置有相关联的摄像机（18,20,22）。 服务器（11）与混合器（12）和端点设备（15,16,17,19,21）连接。 服务器（11）可操作以向第一端点设备（17）发送第一传输，其使得第一端点设备（17）停止向混频器（12）发送视频分组。 服务器（11）还可操作以向第二端点设备（21）发送第二传输，使得第二端点设备（21）开始向混合器发送视频分组。

Abstract: A method for executing a video conference is provided that includes receiving one or more audio streams at (26) associated with a video conference (12) from one or more end points (12) and determining an active speaker associated with one of the end points (12). Audio information is associated with the active speaker may be received at one or more of media switches. One or more video streams may be suppressed except for a selected video stream associated with the active speaker, the selected video stream propagating to one or more of the media switches during the video conference. The selected video stream may be replicated such that it may be communicated to one or more of the end points associated with a selected one of the media switches (26).

Abstract: A system and method for providing fault tolerant IP services includes establishing a first communication session between an originating telephony device and an application server, through a primary call manager. Failure of the primary call manager may be detected. A second communication session between the application server and a destination telephony device may be established via a back-up call manager. The first communication and the second communication session may be coupled at the application server to establish two-way communication between the originating telephony device and the destination telephony device.
