Este documento describe cómo el flujo de llamada porta del error de la Voz de cliente de Cisco (CVP) trabaja.
Cisco recomienda que tenga conocimiento sobre estos temas:
La información que contiene este documento se basa en estas versiones de software:
La información que contiene este documento se creó a partir de los dispositivos en un ambiente de laboratorio específico. Todos los dispositivos que se utilizan en este documento se pusieron en funcionamiento con una configuración verificada (predeterminada). Si tiene una red en vivo, asegúrese de entender el posible impacto de cualquier comando.
Cuando el servicio de la supervivencia no se habilita en el CUBO o el gateway de ingreso, el flujo del error del CVP invoca un cvperror.tcl configuró en el ingreso Gateway/CUBE o VXML Gateway/CVVB. Se acciona este Tool Command Language (TCL) cuando una escritura de la etiqueta 92929292 generada por el CVP se envía al ingreso Gateway/CUBE en un SORBO 302 movido temporalmente o SORBO REFIERE el mensaje.
El SORBO REFER se realiza solamente cuando el CVP ha contestado ya a la llamada. El CVP hace una reorientación cuando la llamada no se ha contestado. En este caso, envía 302 movidos temporalmente al intiator de la llamada (ingreso Gateway/CUBE), que incluye un destino de la reorientación en la encabezado del contacto.
Sin importar el SORBO REFIÉRASE o 302 movidos temporalmente mensaje, la tarea principal del script cvperror.tcl es jugar un mensaje de Error crítico salvado en el flash en el ingreso Gateway/CUBE o VXML Gateway/CVVB.
Flujo de llamada:
Public Switch Telephone Network (PSTN)
Diales 98041 del teléfono 4008 ------ PSTN (CUCM)------SORBO-----CVP-----ICM----- (el ICM está abajo)
La supervivencia no se habilita en el CUBO

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.
En este escenario puesto que el sorbo del servicio suplementario movido-temporal se habilita por abandono, el gateway adelante la llamada al terminal original, en este caso el PSTN (en el laboratorio, CUCM). Sin embargo, puesto que el PSTN no tiene un trunk del SORBO al CVVB, el mensaje de Error crítico no juega y las desconexiones de la llamada.
En conclusión, la escritura de la etiqueta de 929292 errores se debe configurar y controlar por el gateway. No es relevante qué usted ha configurado en el destino de la sesión en el dial peer de entrada 929292 en el Gateway/CUBE, puesto que este dial-peer no se utiliza para ningún tramo de salida de la llamada.
