Dans le cadre de la documentation associée à ce produit, nous nous efforçons d’utiliser un langage exempt de préjugés. Dans cet ensemble de documents, le langage exempt de discrimination renvoie à une langue qui exclut la discrimination en fonction de l’âge, des handicaps, du genre, de l’appartenance raciale de l’identité ethnique, de l’orientation sexuelle, de la situation socio-économique et de l’intersectionnalité. Des exceptions peuvent s’appliquer dans les documents si le langage est codé en dur dans les interfaces utilisateurs du produit logiciel, si le langage utilisé est basé sur la documentation RFP ou si le langage utilisé provient d’un produit tiers référencé. Découvrez comment Cisco utilise le langage inclusif.
Cisco a traduit ce document en traduction automatisée vérifiée par une personne dans le cadre d’un service mondial permettant à nos utilisateurs d’obtenir le contenu d’assistance dans leur propre langue. Il convient cependant de noter que même la meilleure traduction automatisée ne sera pas aussi précise que celle fournie par un traducteur professionnel.
Ce document décrit le fonctionnement du flux d'appels d'erreur Cisco Customer Voice Portal (CVP).
Cisco vous recommande de prendre connaissance des rubriques suivantes :
Les informations contenues dans ce document sont basées sur les versions de logiciel suivantes :
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. Si votre réseau est en ligne, assurez-vous de bien comprendre l’incidence possible des commandes.
Lorsque le service Survivability n'est pas activé dans CUBE ou la passerelle d'entrée, le flux d'erreur CVP appelle un cvperror.tcl configuré soit dans la passerelle d'entrée/CUBE, soit dans la passerelle VXML/CVB. Ce langage de commande d'outil (TCL) est déclenché lorsqu'une étiquette 92929292 générée par CVP est envoyée à la passerelle d'entrée/CUBE dans un message SIP 302 Déplacé temporairement ou SIP REFER.
SIP REFER n'est exécuté que si CVP a déjà répondu à l'appel. CVP effectue une redirection lorsque l'appel n'a pas obtenu de réponse. Dans ce cas, il envoie un 302 Déplacé temporairement à l'initiateur de l'appel ( Passerelle d'entrée/CUBE ), qui inclut une destination de redirection dans l'en-tête du contact.
Quel que soit le message SIP REFER ou 302 Moved Temporairement, la tâche principale du script cvperror.tcl consiste à lire un message d'erreur critique stocké dans la mémoire Flash sur la passerelle d'entrée/CUBE ou la passerelle VXML/CVB.
Flux d'appels :
Réseau téléphonique de commutation public (RTPC)
Téléphone 4008 Numéros 98041 — PSTN (CUCM)—SIP—CVP—ICM— (ICM en panne)
La survie n'est pas activée dans CUBE
Dans le plan de numérotation CVP, l'étiquette 929292 pointe vers CUBE, comme l'illustre l'image.

Dans ce scénario, étant donné que le SIP de service supplémentaire déplacé temporairement est désactivé dans la passerelle, le message 302 déplacé temporairement n'est pas pris en charge et une erreur interne est signalée à CVP par la passerelle.
Dans le plan de numérotation CVP, l'étiquette 929292 pointe vers CVB comme l'illustre l'image.

Même comportement que la Scénarion 2, puisque le SIP de service supplémentaire déplacé temporairement est désactivé dans la passerelle, le message 302 Déplacé Temporairement n'est pas pris en charge et une erreur interne est signalée au CVP par la passerelle.
Dans le plan de numérotation CVP, l'étiquette 929292 pointe vers CVB comme l'illustre l'image.

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.
Dans ce scénario, étant donné que le SIP de service supplémentaire déplacé temporairement est activé par défaut, la passerelle transfère l'appel à l'initiateur, dans ce cas le RTPC (dans les travaux pratiques, CUCM). Cependant, comme le RTPC ne dispose pas d'une liaison SIP vers le CVB, le message d'erreur critique ne s'affiche pas et l'appel se déconnecte.
En conclusion, l'étiquette d'erreur 929292 doit être configurée et contrôlée par le modem routeur. Ce que vous avez configuré dans la cible de session sur le terminal de numérotation dial-peer 929292 entrant dans la passerelle/CUBE n'est pas pertinent, car ce terminal de numérotation dial-peer n'est utilisé pour aucun segment d'appel sortant.
