UCCX指令碼中的Exception步驟最佳做法
簡介
本文檔介紹如何在Unified Contact Center Express(UCCX)指令碼中配置OnException Goto步驟。
許多呼叫流程中出現的問題是由不正確使用此步驟造成的。此最佳實踐旨在使用此功能時防止呼叫流程和引擎級別出現問題。
問題
ContactInactiveException 的OnException用於您已斷開呼叫（不再活動），即在遠端終止的情形。
這些影象顯示了配置此步驟的常用方法，並使Goto步驟指向指令碼的結尾。
但是在錯誤的情況下請參閱此映像，對於已斷開連線的呼叫，在End標籤之後會使用Terminate步驟。
發生的情況是，當在執行指令碼期間斷開呼叫時，OnException步驟將執行1000次並生成警報(「已到達的最大步驟數：1000")。 雖然此錯誤不會影響引擎或生產，但它是引擎上的問題，並且會生成警報。
原因是，終止已處於非活動狀態（被遠端方放棄）的呼叫會導致生成另一個ContactInactiveException。
實際上，聯絡非活動例外會持續循環並生成，這將生成更多例外。它是Exception循環。

解決方案
要解決此問題，需要在Goto Label之後跳過Terminate步驟，即，請參見圖2，在Terminate步驟之後配置Goto步驟的END標籤步驟，或者完全刪除OnException步驟和相應的END標籤。
摘要不會終止已處於活動狀態的呼叫並嘗試捕獲ContactInactive異常。這在邏輯上是有缺陷的。
這是正確指令碼的影象。
