    • A voicemail system enabling various components of the voicemail system to be distributed geographically yet operate as a seamlessly integrated system is disclosed. A signal gateway interfaces with a telephone network. In addition, one or more media servers interface with the signal gateway as well as the telephone network. The signal gateway is configured to block calls to malfunctioning media servers. The signal gateway monitors the media servers, and responsive to determining that a media server has malfunctioned, the signal gateway initiates auto-blocking such that the telephone network does not route calls to the malfunctioning media server. In addition, the signal gateway is configured to auto-detect a media server responsive to the media server being initialized. The voicemail system can include a variety of other elements, such as one or more system management units and one or more central data and message store systems. Each of the elements in the voicemail system communicate with each other over an internet protocol type network. Any functions in the various elements that require interfacing with the telephone network are simply handled through the signal gateway.
    • 公开了一种语音邮件系统,其使语音邮件系统的各种组件能够在地理上分布,并且作为无缝集成的系统运行。 信号网关与电话网络接口。 此外,一个或多个媒体服务器与信号网关以及电话网络接口。 信号网关被配置为阻止对故障的媒体服务器的呼叫。 信号网关监视媒体服务器,并且响应于确定媒体服务器发生故障,信号网关发起自动阻止,使得电话网络不将呼叫路由到故障媒体服务器。 此外,信号网关被配置为响应于正在初始化的媒体服务器自动检测媒体服务器。 语音邮件系统可以包括各种其他元素,诸如一个或多个系统管理单元和一个或多个中央数据和消息存储系统。 语音邮件系统中的每个元素通过互联网协议类型的网络彼此通信。 需要与电话网络接口的各种元件中的任何功能都可以通过信号网关进行处理。

    • Methods and systems for extending the IMS/SIP architecture of the NGN to provide QoS service to generic bearer flows. Providing QoS treatment, of a bearer flow within a communication session established between two end devices using a different in-band signalling protocol is supported. A Signalling Inter-Working Function (SIWF) is provided in a path of the in-band signalling between the two end devices. The SIWF is operative to: detect at least a signal state of the in-band signalling; and establish a communications session with QoS treatment of bearer flows spanning at least a portion of an end-to-end path between the two end points, based on the detected signal state.
    • 用于扩展NGN的IMS / SIP架构以向通用承载流提供QoS服务的方法和系统。 支持使用不同带内信令协议在两个终端设备之间建立的通信会话内的承载流的QoS处理。 在两个终端设备之间的带内信令的路径中提供信令互通功能(SIWF)。 SIWF可操作用于:至少检测带内信令的信号状态; 并且基于检测到的信号状态,建立与跨越两个端点之间的端对端路径的至少一部分的承载流的QoS处理的通信会话。
