Abstract: A communication device sends a Session Initiation Protocol (SIP) INVITE message to establish a call. In response, the call is forked. For example, in parallel forking, the SIP INVITE may be sent to two different communication devices. The forking causes each communication device to send at least one provisional response message. In this case, first and second SIP provisional response messages are received that include Session Description Protocol (SDP) information for a media stream. A first media stream associated with one of the first or second SIP provisional response messages is received and played. A second media stream associated with the other one of the first or second SIP provisional response messages is received within a first time period. In response to receiving the second media stream within the first time period, the first media stream is discarded and the second media stream is played.

Abstract: A communication system, method, and components are described. Specifically, a communication system having the ability to carry a transitive context and communicate the transitive context to new participant user agents for continuity through all related call dialogs is disclosed. The transitive context communication is possible through the use of a newly created SIP dialog using a REFER message and/or an INVITE message for all call flows and topology change operations.

Abstract: Provided herein are system and methods whereby a speaker in a webconference may take control of a pointer that is visible to other participants of the webconference. Speaker detection identifies the speaker, or “active talker,” and then provides, or offers, pointer control to the detected speaker. The speaker may then be able to utilize their client device's input device, such as a mouse, touchpad, or other pointer control mechanism to control a common pointer visible to the other participants of the webconference. The a host of the webconference maintains control of the other aspects of the webconference, as well, administrative control of the pointer and may, for example, rescind pointer assignment given to a particular “active talker.”

Abstract translation: 这里提供了系统和方法，其中网络会议中的扬声器可以控制对于该会议的其他参与者可见的指针。 扬声器检测识别扬声器或“主动扬声器”，然后提供或提供指示灯控制到所检测到的扬声器。 扬声器然后可以能够利用其客户端设备的输入设备，例如鼠标，触摸板或其他指针控制机制来控制对于该会议的其他参与者可见的公共指针。 网络会议的主机维护对网络会议的其他方面的控制，以及指针的管理控制，并且可以例如撤销给予特定的“主动谈话者”的指针分配。

Abstract: Webconferences are streamed presentations generally containing video and audio portions. Layering the visual aspects of the presentation allows the streamed content to be displayed on a background layer. Embodiments are provided by which a captured image is created of a particular scene. The image is held on the display for a viewer to annotations. The image is presented in a layer on top of the background layer thereby freezing a live presentation. When the user has completed their annotations, the next scene is displayed and additional annotations may be applied to the next scene. A composite presentation file may then be saved at the end of the webconference containing local annotations and/or public presentation material. Alternatively, the layer with the captured image is hidden and live content of the background image redisplayed.

Abstract translation: 网络会议是通常包含视频和音频部分的流式演示文稿。 分层演示的视觉方面允许流媒体内容显示在背景层上。 提供了通过特定场景创建拍摄图像的实施例。 图像被保持在显示器上以供观看者注释。 图像呈现在背景层顶部的层中，从而冻结实况表现。 当用户完成其注释时，显示下一个场景，并且附加注释可以应用于下一个场景。 然后可以在包含本地注释和/或公共呈现材料的网络会议的结尾处保存复合呈现文件。 或者，具有捕获图像的图层被隐藏，并且重新显示背景图像的实时内容。
