    • Systems, methods, and computer program products are provided for manual ring-down communication using Session Initiation Protocol (SIP). A first SIP user agent transmits a message to a second SIP user agent over an Internet Protocol (IP) network to establish a SIP session. The first SIP user agent determines that a signal key associated with a first communication device has been selected and transmits, to the second SIP user agent over the IP network, a start event message to cause a second communication device to activate an alert. The first SIP user agent determines that the signal key has been released and transmits over the IP network an end event message to deactivate the alert. The first SIP user agent transmits, to the second SIP user agent over the IP network, one or more subsequent INVITE messages at a predetermined repetition rate to refresh the SIP session.
    • 系统,方法和计算机程序产品提供了使用会话发起协议(SIP)的手动通话。 第一SIP用户代理通过因特网协议(IP)网络向第二SIP用户代理发送消息以建立SIP会话。 第一SIP用户代理确定已经选择与第一通信设备相关联的信号密钥,并且通过IP网络向第二SIP用户代理发送开始事件消息以使第二通信设备激活警报。 第一个SIP用户代理确定信号密钥已经被释放,并通过IP网络发送结束事件消息以停用警报。 第一SIP用户代理以预定的重复率向IP网络上的第二SIP用户代理发送一个或多个后续的INVITE消息来刷新SIP会话。

    • An Open SIP Protocol Stack provides a variety of functions within a SIP-based telecommunications network. A set of cooperating layers including a transport layer, a transaction layer and a transaction user core layer. Various processes in these layers index into an associated configuration database designed in accordance with the present invention. The configuration database includes plurality of “mini-stacks.” When a particular transaction is being processed by one of the layers of the Open SIP Protocol Stack, PPL state machines that are to be utilized for that process are “loaded” with the appropriate information from the mini-stack for that attribute. Techniques for transaction processing and editing state machines are also provided by the Open SIP Protocol Stack of the present invention. The Open SIP Protocol Stack may be deployed in a SIP/PSTN gateway, a SIP Application Server, a SIP Media Server, a SIP Redirect Server and a SIP Registrar.
    • 开放SIP协议栈在基于SIP的电信网络内提供多种功能。 一组合作层,包括传输层,事务层和事务用户核心层。 这些层中的各种过程索引到根据本发明设计的相关配置数据库中。 配置数据库包括多个“小型堆栈”。 当特定事务正在由开放SIP协议栈的层之一处理时,用于该进程的PPL状态机将从该属性的小型堆栈中加载适当的信息。 用于交易处理和编辑状态机的技术也由本发明的开放SIP协议栈提供。 开放SIP协议栈可以部署在SIP / PSTN网关,SIP应用服务器,SIP媒体服务器,SIP重定向服务器和SIP注册器中。
