摘要： The present invention provides a method for maintaining a communication session between telephony devices, which includes establishing a first TCP/IP signaling communication link between a first telephony device and a proxy. The first TCP/IP signaling communication link is operable to communicate first keep alive signals between the proxy and the first telephony device. A second TCP/IP signaling communication link is established between a primary gatekeeper and the proxy. The second TCP/IP signaling communication link is operable to communicate second keep alive signals between the proxy and the primary gatekeeper. The first and second TCP/IP signaling communication links are terminated at the proxy. Therefore, a communication session between the first telephony device and a second telephony device may be maintained even if the second keep alive signals are interrupted.

摘要： A method for executing a video conference is provided that includes receiving one or more audio streams associated with a video conference from one or more end points and determining an active speaker associated with one of the end points. Audio information associated with the active speaker may be received at one or more 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.

摘要： A method and system for determining a relative location of a device on a network is provided. In this system and method, a list of landmark nodes provided on the network is received. Then, a value which is a time, a latency and/or a distance from the device to each of the landmark nodes is determined. Each of the determined values corresponding to the respective node of the landmark nodes is transmitted to a central arrangement to provide the relative location of the device with respect to the landmark nodes.

摘要： A method and apparatus for recovering a call resource from a call session are disclosed. A call resource detects if a media stream communicated from a device via a communication network becomes inactive during the call session and deletes the inactive media stream. The call resource deletes the inactive media streams until one media stream remains in the call session, which is terminated to release the call resource from the call session.

摘要： Techniques are provided for using a location of a caller placing a call that is received at a call center to identify other sources of information that are relevant to the call. A call is received at a call center from a caller. The location of the caller is obtained from the received call, and other sources of information potentially relevant to the call are identified based on the location of the caller. For example, information is stored that identifies at lease one individual that is proximate to the location of the caller, and communication is initiated with at least one individual who is determined to be located proximate to the caller.

摘要： In one embodiment, an apparatus includes a first module that causes the first endpoint to receive a current speaker's video stream if the first endpoint is not the current speaker and to receive a last speaker's video stream if the first endpoint is the current speaker. The apparatus includes a second module that causes the second endpoint to receive a continuous presence, current speaker video stream if the second endpoint is not the current speaker and to receive a continuous presence, last speaker video stream if the second endpoint is the current speaker. The continuous presence, current speaker video stream comprises two or more video streams, one of which includes at least a portion of the current speaker's video stream. The continuous presence, last speaker video stream comprises two or more video streams, one of which includes at least a portion of a last speaker's video stream.
