Passo della procedura consigliata sull'eccezione nello script UCCX
Introduzione
In questo documento viene descritto come configurare il passaggio OnException Goto in uno script Unified Contact Center Express (UCCX).
I problemi rilevati in molti flussi di chiamata sono causati da un utilizzo non corretto di questo passaggio. Questa procedura ottimale ha lo scopo di prevenire problemi nel flusso di chiamate e nel livello del motore durante l'utilizzo di questa funzione.
Problema
L'oggetto OnException per un oggetto ContactInactiveException viene utilizzato per scenari in cui la chiamata è già stata disconnessa (non più attiva), ovvero terminata all'estremità remota.
Queste immagini mostrano un modo comune di configurare questo passaggio e fanno in modo che il passaggio Vai punti alla fine dello script.
Tuttavia, fare riferimento a questa immagine negli scenari errati. Il passaggio Termina viene utilizzato dopo l'etichetta Fine per una chiamata già disconnessa.
Quando si disconnette la chiamata durante l'esecuzione dello script, il passo OnException viene eseguito 1000 volte e genera un avviso ("Numero massimo di passi raggiunto: 1000"). Anche se questo errore non influisce sul motore o sulla produzione, si tratta di un problema del motore che genera un avviso.
La terminazione di una chiamata già inattiva (eliminata dalla parte remota) causa la generazione di un'altra eccezione ContactInactiveException.
In sostanza, Contact Inactive Exceptions viene continuamente ripetuto e generato, il che provoca la generazione di un maggior numero di eccezioni. Si tratta di un ciclo Exception.

Soluzione
Per risolvere il problema, è necessario saltare il passaggio Termina dopo il passaggio Goto Label, ovvero fare riferimento alla figura 2 per configurare il passaggio END del passaggio Goto dopo il passaggio Termina, oppure rimuovere del tutto il passaggio OnException e l'etichetta END corrispondente.
Il riepilogo non prevede l'interruzione di una chiamata InActive e il tentativo di intercettare l'eccezione ContactInactive. Ciò è logicamente errato.
L'immagine mostra lo script corretto.
