    • A system and method, e.g., Voice Proxy Server (VPS), is described for managing Voice over IP (VoIP) services between a NAT enabled private network and a public network such as the Internet. The VPS acts like the Call Agent to the nodes in the private network and it represents an embedded voice client to the real Call Agent in the public network. Each logical line of the VPS corresponds to a real voice line in the private node. VoIP signaling messages may be carried in the payload of the IP packets. VPS will properly translate IP address and/or port number information in the payload to correctly route the signaling data between networks. Additionally, VPS will forward the incoming Real Time Protocol (RTP) packets to the real destination in the private network.
    • 描述了一种系统和方法,例如语音代理服务器(VPS),用于在启用NAT的专用网络和诸如因特网的公共网络之间管理IP语音(VoIP)服务。 VPS的作用就像呼叫代理到专用网络中的节点,它代表一个嵌入式语音客户端到公共网络中的真正呼叫代理。 VPS的每个逻辑线对应于专用节点中的真实语音线。 VoIP信令消息可以在IP分组的有效载荷中承载。 VPS将正确地转换有效载荷中的IP地址和/或端口号信息,以正确路由网络之间的信令数据。 此外,VPS将将传入的实时协议(RTP)数据包转发到专用网络中的真实目的地。

    • Raw presence data from a plurality of presence data sources is collected and processed into unified presence data. Unified presence data over a period of time before a first time is stored in a historical presence data archive. A probability of a presence variable having a specific value is generated based on unified presence data collected and processed at a second time on or after the first time, the historical presence data archive, and user profile data. Presence information is generated based on the probability and the user profile data. Presence data sources include both Session Initiation Protocol based and non Session Initiation Protocol based presence data sources. In an embodiment, non Session Initiation Protocol based unified presence data is transformed into Session Initiation Protocol based unified presence data.
    • 来自多个存在数据源的原始存在数据被收集并处理成统一存在数据。 在第一次之前的一段时间内的统一呈现数据被存储在历史存在数据档案中。 基于在第一时间或之后的第二时间收集和处理的统一存在数据,历史存在数据存档和用户简档数据,生成具有特定值的存在变量的概率。 基于概率和用户简档数据生成存在信息。 存在数据源包括基于会话发起协议和不基于会话发起协议的在线数据源。 在一个实施例中,基于非会话发起协议的统一存在数据被转换为基于会话发起协议的统一存在数据。
