jboss7.x - Sip Servlet - 控制未传递给链中的下一个 Servlet

Question

我正在使用 Mobicents Sip Servlets 3.0.0-SNAPSHOT。我在 DAR 中配置了两个 servlet；一是检查是否正在尝试第三方注册，二是执行实际注册。我发现当 REGISTER 到达时，它被传递给第一个 servlet（BlockerApp）；但是当那个 servlet 完成并代理到下一个时，第二个 servlet (RegApp) 不会被调用。而是再次调用第一个 servlet，并将路由指令设置为 NEW。

有任何想法吗？我错过了什么吗？

DAR 配置：

REGISTER=("RegApp","DAR\:From","ORIGINATING","","NO_ROUTE","1"),("BlockerApp","DAR\:From","ORIGINATING",""," NO_ROUTE","0")

我现在明白为什么它不适合我。使用 DAR 的 SIP Servlet 链接仅适用于具有诸如 INVITE、SUBSCRIBE、NOTIFY 等对话框的方法。我已尝试将 DAR 与处理 INVITE 的多 servlet 应用程序一起使用，并且它按预期工作。
