最佳实践在UCCX脚本的OnException步骤
Introduction
本文描述如何配置在一个统一的Contact Center Express (UCCX)脚本的OnException定位的步骤。
在许多呼叫流看到的问题由不正确使用此步骤引起。此最佳实践在呼叫流和引擎水平瞄准防止问题，当曾经此功能时。
问题
ContactInactiveException的OnException使用您已经断开呼叫的方案(不再激活)，即被终止的在远端。
这些镜像显示一普通方法配置此步骤和有定位的步骤点到结尾的脚本。
然而，请参见在不正确方案的此镜像，终止步骤使用，在末端标签，一次已经断开呼叫后。
什么发生是，当您断开呼叫，当脚本被执行时时， OnException步骤被执行1000次并且生成戒备(“被到达的最大数量步骤：1000")。虽然此错误不影响引擎或生产，它是在引擎的一个问题，并且生成一次戒备。
原因是那终止已经是非激活的呼叫(droped由远端方)造成另一ContactInactiveException生成。
实质上，请与非激活例外联系不断地循环并且生成，造成更多例外生成。它是例外循环。
这些日志显示问题：

解决方案
要调整此问题，您需要跳到终止步骤，在定位的标签，即参考图2配置Gotostep的END标签步骤afterthe终止步骤或者一共去除OnExceptionstep和对应的END标签后。
汇总不是终止一次已经非激活呼叫和设法捉住ContactInactive例外。这是逻辑上有缺陷的。
这是正确的脚本的镜像。
