摘要： A method of expediting resource negotiation in a modified Session Initiation Protocol (SIP) reduces the number of messages exchanged for resource negotiation, thereby reducing the latencies involved in session setup. The method entails sending an INVITE message having a modified SIP header containing an indication that the originator's terminal seeks a fast session setup. The INVITE message further contains a list of all codecs available at the originator's terminal and how many each type of media component are required. These codecs can be provided in an order of preference. The answerer selects the codecs for the requested media types from the list of available codecs without engaging in a back-and-forth resource negotiation for the codecs. The result is that the session can be set up with fewer messages which provides quicker session setup than in the prior art.

摘要： An enhanced communication bridge includes a context interface that enables the audio bridge to learn information about the type of Voice encoder, device, network connection, location, type of call (business vs. personal), identity and position of the individual, and other information about the context of the communication session itself as well as the context of each person joining the communication session. This context information is used to determine how quality of experience targets for the communication as a whole, as well as how each individual contribution should be uniquely processed to attempt to meet the quality of experience targets. Business factors may influence the decision as to the type of processing to be implemented on each of the signals provided by the participants. Corrective action may also be implemented by the bridge on the client network devices as well in the embodiment. The bridge may be centralized or distributed. A video bridge may be implemented as well.
摘要翻译：增强的通信桥包括上下文接口，其使得音频桥可以了解关于语音编码器，设备，网络连接，位置，呼叫类型（业务对个人），个体的身份和位置以及其他信息的信息关于通信会话本身的上下文以及加入通信会话的每个人的上下文。该上下文信息用于确定整个通信的体验质量的质量以及如何独立处理每个个体贡献以尝试满足体验质量的目标。业务因素可能影响对参与者提供的每个信号执行的处理类型的决定。在实施例中也可以通过客户端网络设备上的桥来实现纠正动作。桥可以集中或分布。也可以实现视频桥。
