Flujo de llamadas de la puerta de enlace de entrada PSTN del IOS al CVP (cola y recopilación de llamadas)
Contenido
Introducción
Cisco Customer Voice Portal (CVP) proporciona aplicaciones de respuesta de voz interactiva (IVR) e inteligente a las que se puede acceder a través del teléfono. Hay tres tipos de implementaciones de CVP:
-
Servicio independiente
-
Control de llamadas CVP
-
Colección y cola de llamadas
Este documento describe el flujo de llamadas desde la perspectiva de la gateway de ingreso basada en H.323 IOS® en una implementación de Call Queue and Collect.
En la implementación de cola de llamadas y recopilación, CVP interactúa con Intelligent Contact Management (ICM) para tomar decisiones de enrutamiento de llamadas. ICM solicita al CVP que proporcione el tratamiento de la Unidad de respuesta de voz (VRU) a la llamada entrante para reproducir avisos del menú y recopilar dígitos para determinar el grupo de habilidades que se va a seleccionar. Cuando se ha identificado el grupo de habilidades y hay disponible un agente del grupo de habilidades, ICM solicita al CVP que conecte la llamada entrante al teléfono IP del agente a través de Cisco CallManager. Si el agente no está disponible, ICM solicita al CVP que proporcione el tratamiento de la cola de llamadas (por ejemplo, reproducir un mensaje de música en espera). CVP proporciona tratamiento de VRU o de cola de llamadas mediante una puerta de enlace VXML.

Ejemplo de Flujo de Llamada
Esta sección describe el flujo de llamada que resulta de este ejemplo de configuración:
-
Una llamada ISDN llega a la puerta de enlace PSTN/VXML a través de T1 PRI 1/0/0.
-
La puerta de enlace del IOS coincide con el par de marcado POTS 2 como el par de marcado entrante para esta llamada.
-
La puerta de enlace del IOS coincide con el par de marcado VoIP 1 como el par de marcado saliente para esta llamada.
-
La puerta de enlace del IOS precede el prefijo técnico "2#" al número llamado y envía un ARQ al control de acceso.
-
El control de acceso enruta la llamada al CVP.
-
CVP responde a la llamada y se establece la conexión de medios RTP entre el gateway de ingreso IOS y CVP.
-
CVP informa a ICM sobre la nueva llamada.
-
ICM ejecuta la secuencia de comandos asociada al número llamado de esta llamada.
-
ICM solicita a CVP que proporcione el tratamiento VRU para reproducir un mensaje de Menú (Main_Welcome_Menu.wav) y recopilar dígitos para identificar el grupo de habilidades.
-
1 para TAC
-
2 para ventas
ICM también envía la etiqueta ICM (8001112222) de la VRU de red a CVP.
-
-
CVP envía una solicitud ARQ (con destino = etiqueta de VRU de red) al control de acceso.
-
El control de acceso proporciona la dirección IP de la puerta de enlace VXML en la respuesta ACF.
-
CVP envía una configuración de H225 a la puerta de enlace VXML que establece una sesión VXML a CVP. Consulte estas URL para comprender las interacciones de VXML Gateway y CVP, VXML Gateway y ASR/TTS Server:
-
CVP desconecta su conexión de medios RTP existente a la puerta de enlace de entrada enviando el TCS vacío H245.
-
CVP establece una conexión de medios RTP entre la puerta de enlace de entrada y la puerta de enlace VXML.
-
La persona que llama a PSTN ingresa el dígito "1" para seleccionar el grupo de habilidades "TAC". La puerta de enlace de entrada envía el DTMF a través de RTP NTE a la puerta de enlace VXML 16). La puerta de enlace VXML informa los dígitos al CVP a través de VXML que luego informa al ICM.
-
La puerta de enlace VXML informa los dígitos al CVP a través de VXML que luego informa al ICM.
-
A continuación, ICM encuentra un agente disponible del grupo de habilidades seleccionado y solicita a CVP que enrute la llamada al agente enviando la etiqueta ICM (3#75001) del agente.
-
CVP desconecta la conexión de medios RTP existente entre la puerta de enlace de entrada y la puerta de enlace VXML.
-
CVP envía una solicitud ARQ (con destino = etiqueta de agente) al control de acceso.
-
Gatekeeper proporciona la dirección IP del Cisco CallManager en la respuesta ACF.
-
CVP envía una configuración de H225 a Cisco CallManager que luego establece una llamada al teléfono IP del agente.
-
CVP establece una conexión de medios RTP entre la puerta de enlace de entrada y el teléfono del agente.
-
La persona que llama a PSTN cuelga la llamada después de finalizar la conversación con el agente.
-
La puerta de enlace de entrada desconecta la llamada al CVP e informa al gatekeeper sobre la terminación de la llamada.
-
CVP desconecta la llamada a CCM.
