我正在尝试使用UCMA 4.0基本会议示例和第一个用户端点在建立呼叫时停止会议（它的lync没有振铃）。一段时间后会触发超时异常。主要问题是什么？
BTW，平台正在启动，发现已建立3个应用程序端点。SIP：kl.dev.local@dev.local; GRUU;不透明= SRVR：yyapp：EHghH8UXNVqIedXU3YgJyQAAYYApp SIP：kl.cdev.local@dev.local; GRUU;不透明= SRVR：yyapp：EHghH8UXNVqIedXU3YgJyQAAMachine1 SIP：kl.dev.local@dev.local; GRUU;不透明= SRVR：yyapp：EHghH8UXNVqIedXU3YgJyQAAMachine2 SIP：kl.dev.local@dev.local; GRUU;不透明= SRVR：yyapp：EHghH8UXNVqIedXU3YgJyQAAMachine3 'LyncGame.Gateway.TestConnection.vshost.exe'（CLR v4.0.30319：LyncGame.Gateway.TestConnection.vshost.exe）：已加载'C：\ Windows \ Microsoft.Net \ assembly \ GAC_MSIL \ System.Data.SqlXml \ v4 .0_4.0.0.0__b77a5c561934e089 \ System.Data.SqlXml.dll”。跳过加载符号。模块已经过优化，调试器选项“Just My Code”已启用。 'LyncGame.Gateway.TestConnection.vshost.exe'（CLR v4.0.30319：LyncGame.Gateway.TestConnection.vshost.exe）：已加载'System.Xml.Xsl.CompiledQuery.1'。 线程0x6e8已退出代码259（0x103）。 线程0x3dd4已退出代码259（0x103）。 线程0x2138已退出代码259（0x103）。 'LyncGame.Gateway.TestConnection.vshost.exe'（CLR v4.0.30319：LyncGame.Gateway.TestConnection.vshost.exe）：已加载'C：\ Windows \ Microsoft.Net \ assembly \ GAC_MSIL \ System.Security \ v4.0_4 .0.0.0__b03f5f7f11d50a3a \ System.Security.dll”。跳过加载符号。模块已经过优化，调试器选项“Just My Code”已启用。 线程0x3180已退出，代码为259（0x103）。 线程0x350c已退出代码259（0x103）。 线程0x1698已退出，代码为0（0x0）。 线程0x3ef4已退出代码0（0x0）。 线程0x3f00已退出代码259（0x103）。 线程0x2a24已退出代码259（0x103）。 线程0x3fc0已退出代码259（0x103）。 线程0x3750已退出，代码为259（0x103）。 线程0x27b8已退出代码259（0x103）。 线程0x11e0已退出代码259（0x103）。 线程0x2214已退出，代码为259（0x103）。 线程0x1564已退出，代码为259（0x103）。 线程0x3740已退出，代码为259（0x103）。 线程0x28a8已退出代码259（0x103）。 线程0x1da8已退出代码259（0x103）。 Microsoft.Rtc.Collaboration.dll中出现“Microsoft.Rtc.Signaling.OperationTimeoutException”类型的第一次机会异常

答案 0 :(得分：0)
这里真正有用的另一件事是在应用程序服务器上运行OCSLogger并查看返回的内容。您可以运行S4以获取SIP跟踪。可能只是像你一样简单，无法在5061（或你在配置中指定的任何回调端口）上接收消息。如果它只在A / V上失败，请查看SDP提供/回答中正在使用的地址，并查看这些地址是否也可以访问。同样，OCSLogger（或Lync CLS）和Snooper也是您的朋友。
