摘要： A conferencing system includes a mixer operable to process audio and video packets received from a plurality of endpoint devices, and to transmit a processed audio/video stream back to the endpoint devices. A server connects with the mixer and the endpoint devices. The server is operable to send a first transmission to a first endpoint device that causes the first endpoint device to stop transmitting video packets to the mixer. The server is further operable to send a second transmission to a second endpoint device that causes the second endpoint to start transmitting video packets to the mixer. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要翻译：会议系统包括可操作以处理从多个端点设备接收的音频和视频分组的混合器，以及将经处理的音频/视频流发送回端点设备。服务器与混音器和端点设备连接。服务器可操作地向第一端点设备发送第一传输，其使得第一端点设备停止向混合器传输视频分组。服务器还可操作以将第二传输发送到第二端点设备，其使得第二端点开始向混合器发送视频分组。要强调的是，该摘要被提供以符合要求抽象的规则，允许搜索者或其他读者快速确定技术公开内容的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。

摘要： A Real-Time Protocol (RTP) source node of a network operates to send a first data packet of a first size to a destination node over a path of the network that includes a plurality of intermediate nodes, at least one of the intermediate nodes having a maximum transmission unit (MTU) size smaller than the first size such that fragmentation of the first data packet occurs. The destination node sends back to the source node a RTCP report that includes a number of fragments received and a largest minimum data packet size. In response, the source node sends subsequent data packets having a second size less than or equal to the largest data packet size of the fragments. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要翻译：网络的实时协议（RTP）源节点操作以通过包括多个中间节点的网络的路径向目的地节点发送第一大小的第一数据分组，至少一个中间节点具有最小传输单元（MTU）的大小小于第一大小，使得第一数据分组的碎片发生。目的地节点向源节点发送包含接收到的片段数和最大最小数据包大小的RTCP报告。作为响应，源节点发送具有小于或等于片段的最大数据分组大小的第二大小的后续数据分组。要强调的是，该摘要被提供以符合要求抽象的规则，允许搜索者或其他读者快速确定技术公开内容的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。

摘要： According to one embodiment of the invention, a method for use in establishing communications includes receiving an invitation for communication at a first device. The invitation for communication is devoid of video capability information. In response to receiving the invitation for communication, the method includes transmitting, from the first device, a signal other than an SDP signal. This signal includes video capability information. After transmission of the signal, the first device receives an offer and incorporates the video capability information included in the signal.

摘要： In a particular embodiment, a disconnect message with a progress indicator may be received in a PSTN protocol at a gateway. The gateway determines if the disconnect message includes a progress indicator. The gateway then generates a SIP message with a reason indicator that indicates the SIP message is mapped from a disconnect message that includes the progress indicator. The SIP message is then sent to a second gateway. The second gateway determines that the SIP message should be interworked to a disconnect message. The second gateway uses the reason indicator in the SIP message to determine this. Accordingly, the second gateway sends a disconnect with progress indicator to a second PBX. This allows the second PBX the option to either listen to an in-band announcement or to disconnect without listening to the in-band announcement.
摘要翻译：在特定实施例中，具有进度指示符的断开消息可以在网关的PSTN协议中被接收。网关确定断开连接消息是否包含进度指示器。然后，网关生成具有指示SIP消息从包括进度指示符的断开消息映射的原因指示符的SIP消息。然后将SIP消息发送到第二个网关。第二个网关确定SIP消息应该与断开消息互通。第二个网关使用SIP消息中的原因指示符来确定这一点。因此，第二网关将进程指示符断开连接发送到第二PBX。这允许第二PBX的选项是收听带内公告或断开连接而不收听带内公告。

摘要： In one embodiment, a session is refreshed using a message that is simplified for refresh purposes. The refresh message that is used is a message used for another purpose in a protocol (e.g., SIP). For example, a reINVITE message may be used as a refresh message. If the reINVITE message is used for its intended purpose, the reINVITE message may be used to change the characteristics of a session. This reINVITE message includes an SDP and full header such that the parameters can be properly changed. However, the reINVITE message may be used to refresh a session. This may be referred to as a simple refresh message. But, the simple refresh message does not include an SDP or any other message body. The simple refresh message includes only a reduced header. This reduces time spent building and parsing the simple refresh message.
