Funktionsweise des CVP-Fehleranrufflusses
Inhalt
Einführung
In diesem Dokument wird beschrieben, wie der Anruffluss beim Cisco Customer Voice Portal (CVP) Error funktioniert.
Voraussetzungen
Anforderungen
Cisco empfiehlt, über Kenntnisse in folgenden Bereichen zu verfügen:
- CVP-Server
- Cisco Unified Intelligent Contact Management (ICM)
- Cisco Unified Contact Center Enterprise (UCCE)
Verwendete Komponenten
Die Informationen in diesem Dokument basieren auf den folgenden Softwareversionen:
- CVP-Server 11.5
- Cisco Virtual Voice Browser (CVVB) 11.5
- Cisco Unified Border Element (CUBE)
- Cisco Voice eXtensible Markup Language (VXML)-Gateway
- Cisco Unified Call Manager (CUCM) 11.0
- Session Initiation Protocol (SIP)
Die Informationen in diesem Dokument wurden von den Geräten in einer bestimmten Laborumgebung erstellt. Alle in diesem Dokument verwendeten Geräte haben mit einer leeren (Standard-)Konfiguration begonnen. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die potenziellen Auswirkungen eines Befehls verstehen.
Hintergrundinformationen
Wenn der Survivability-Service im CUBE oder im Ingress Gateway nicht aktiviert ist, ruft der CVP-Fehlerfluss eine cvperror.tcl auf, die entweder im Ingress Gateway/CUBE oder im VXML-Gateway/CVVB konfiguriert wurde. Diese Tool Command Language (TCL) wird ausgelöst, wenn ein vom CVP generiertes 929292-Label an das Eingangs-Gateway/CUBE in einer temporären oder SIP-REFER-Nachricht von SIP 302 gesendet wird.
SIP REFER wird nur ausgeführt, wenn CVP den Anruf bereits entgegengenommen hat. CVP führt eine Umleitung durch, wenn der Anruf nicht beantwortet wurde. In diesem Fall sendet er eine temporäre 302-Nachricht an den Initiator des Anrufs ( Ingress Gateway/CUBE ), die ein Umleitungsziel im Contact-Header enthält.
Unabhängig von der Meldung "SIP REFER" oder "302 Moved Temporally" besteht die Hauptaufgabe des Skripts "cvperror.tcl" darin, eine kritische Fehlermeldung abzuspielen, die im Flash-Speicher auf dem Ingress Gateway/CUBE oder VXML Gateway/CVVB gespeichert ist.
CVP-Fehleranrufverlauf - 302 vorübergehend verschoben
Anrufablauf:
Public Switch Telefone Network (PSTN)
Telefon 4008 wählt 98041 - PSTN (CUCM) - SIP - CVP - ICM - (ICM ist ausgefallen)
Überlebensfähigkeit ist in CUBE nicht aktiviert.
Szenario 1: Im Gateway konfiguriertes CVP-Fehler-TCL
Konfiguration in CVP
Im CVP-Wählplan verweist das 929292-Label auf CUBE, wie im Bild gezeigt.

In diesem Szenario leitet das Gateway den Anruf an den Ersteller weiter, in diesem Fall an das PSTN (im Labor CUCM), da das Service-SIP standardmäßig "Ship-zeitweilig" aktiviert ist.
Szenario 2: Im Gateway konfiguriertes CVP-Fehler-TCL und kein ergänzender Service

Erklärungsszenario 2
In diesem Szenario wird die Meldung 302 Moved Temporär nicht unterstützt, da das Service SIP-Ship-Move-temporär im Gateway deaktiviert ist, und das Gateway meldet dem CVP einen internen Fehler.
Szenario 3: Im VXML-Gateway/CVVB konfiguriertes CVP-Fehler-TCL und kein ergänzender Service
Konfiguration in CVP
Im CVP-Wählplan verweist das 929292-Label auf CVVB, wie im Bild gezeigt.

Ähnliches Verhalten wie Szenario 2: Da das Dienstmodul "Ship-Move-temporär" im Gateway deaktiviert ist, wird die Meldung "302 Moved Temporär" nicht unterstützt, und ein interner Fehler wird dem CVP vom Gateway gemeldet.

At this moment the PSTN must sent a SIP Invite to the CVVB, since there is no SIP trunk between the PSTN and the CVVB,
the critical error message is not played and the call disconnects.
Erklärungsszenario 4
In diesem Szenario leitet das Gateway den Anruf an den Ersteller weiter, in diesem Fall an das PSTN (im Labor CUCM), da das Service-SIP standardmäßig "Ship-zeitweilig" aktiviert ist. Da das PSTN jedoch über keinen SIP-Trunk zum CVVB verfügt, wird die kritische Fehlermeldung nicht angezeigt, und der Anruf wird getrennt.
Zusammenfassend muss das Fehlerlabel 929292 vom Gateway konfiguriert und gesteuert werden. Es ist nicht relevant, was Sie im Sitzungsziel für den eingehenden DFÜ-Peer 929292 im Gateway/CUBE konfiguriert haben, da dieser DFÜ-Peer nicht für ausgehende Anrufabschnitte verwendet wird.
