摘要: A method for adaptive media quality monitoring includes monitoring at least one metric of a call between at least two endpoints and detecting a threshold crossing event via the monitoring of the at least one metric. The method also includes executing a threshold crossing action based on detecting the threshold crossing event. The threshold crossing action comprises monitoring at least one additional metric of the call.

摘要: A method for tracing communications includes receiving trace criteria from a first remote element and determining whether a call signaling message matches the trace criteria. The method includes attaching a trace tag to the call signaling message, if the call signaling message matches the trace criteria. The method further includes transmitting the call signaling message to a second remote element.

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: MPEG data is packetized and streamed using a two phase procedure. First, the system parses MPEG data and reformats it into RTP sized packets in preparation for conversion to an RTP stream. This reformatting phase is done prior to streaming and typically only performed once for each MPEG file and network type. After reformatting, the MPEG data is contained in a modified MPEG bitstream that includes annotations that inform a network server that the modified MPEG stream is specially reformatted to facilitate RTP packetization. In the second phase, a network server encapsulates the reformatted MPEG data within RTP packets and streams the data onto the network for real-time playback. As a result of reformatting the MPEG data prior to transmission, the real-time demands of an MPEG to RTP conversion are greatly reduced.

摘要: Authenticating an endpoint using a STUN server includes facilitating a communication session between a first endpoint and a second endpoint over a network. A challenge request is sent to the second endpoint. The challenge request attempts to authenticate the second endpoint and includes an identification. The identification is associated with an expected response identification. A response to the challenge request is received from the second endpoint. The response has an actual response identification. The received response is verified to establish whether the second endpoint is legitimate. The second endpoint is legitimate if the actual response identification includes the expected response identification.
