摘要： In one embodiment a method is provided which comprises recording a push-to-talk communication session comprising media segments, each media segment being associated with an endpoint device from which the media segment originated. A playback request for playback of at least one recorded media segment at an adjusted playback speed may be received and, in response to the playback request, a playback speed of the at least one recorded media segment may be adjusted relative to another recorded media segment. The recorded media including the segment with the adjusted playback speed may then be provided at a requesting endpoint device.

摘要： In an example embodiment, an example method is provided for echo mitigation in a conference call. In this method, a test audio signal is transmitted to a conference endpoint and as a result, an echo associated with the transmittal of the test audio signal is received. One or more parameters of the echo are then identified and an echo mitigation process is selected from multiple echo mitigation processes based on the identified parameters. The selected echo mitigation process is then applied.

摘要： A conferencing system includes a plurality of ports for network connection to endpoint devices of participants to a conference session. A mixer receives input audio streams from the endpoint devices and then outputs a mixed audio stream back to the endpoint devices. A processor runs a program that automatically downgrades one or more of the participants to the conference session from a full-duplex communication mode to a half-duplex communication mode in response to an event affecting allocation of conferencing resources, the conferencing resources including the ports.

摘要： A method and apparatus for unicast and multicast media processing is provided. The method may comprise receiving multicast packets communicating a plurality of media streams from a plurality of communication endpoints. Each communication endpoint may have an associated individual media stream. The method inspects the multicast packets to identify each individual media stream with which the packet is associated and individually processes each individual media stream. At least one individual media stream is unicast from its associated buffer to a unicast communication endpoint of the plurality of communication endpoints. In an example embodiment, the method may identify media capabilities of the unicast communication endpoint. The plurality of media streams may form part of a virtual talk group (VTG) in an audio conference.

摘要： In one embodiment, a conference with multiple end points is provided. At the locations, multiple screens may be configured to display video from a portion of the multiple end points. Video from multiple locations is output onto the multiple screens, such as video streams from N different segments are output on N different screens. The video output may be determined based on a first dimension of the floor control algorithm. A push-to-talk input may then be received from a button. A video segment associated with the push-to-talk button is then determined and the video segment is output on one of the multiple screens in response to receiving the push-to-talk input. The push-to-talk input may be used by users that cannot actively participate in the first dimension of the floor control algorithm. For example, users using sign language cannot speak louder and thus by using the push to talk button or hand gestures can indicate their desire to be switched in as one of the displayed segments.

摘要： In one embodiment, a method includes establishing a first virtual talk group (VTG) that includes a plurality of endpoints and has a first multicast address. The plurality of endpoints includes a first endpoint and a second endpoint. The method also includes monitoring traffic associated with the first VTG, determining when a denial of service (DOS) attack is indicated by the traffic, and identifying at least one rogue endpoint responsible for the DOS attack when it is determined that the DOS attack is indicated. The first endpoint and the second endpoint are notified that they are to participate in a dynamic switchover to a second VTG when a DOS attack is indicated. The second VTG is established using a second multicast address, and includes the first endpoint and the second endpoint, but not the rogue endpoint.

摘要： Methods and apparatus for reducing the effect of surrounding noise in a push-to-talk (PTT) system are disclosed. In one embodiment, a method includes obtaining a first media stream using a microphone when a PTT functionality of a PTT communications system is in a first state, and identifying a first set of characteristics associated with noise in the first media stream. The method also includes obtaining a second media stream using the microphone that includes the noise and a first sound when the PTT functionality is in a second state. A second set of characteristics associated with the first sound in the second media stream is identified, and parameters associated with a filtering arrangement are determined using the first and second sets of characteristics. Finally, the method includes applying the filtering arrangement to the second media stream to filter out the noise such that a communications stream is created.

摘要： 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.
