Fluxo de chamada do Gateway de entrada PSTN do IOS para CVP (Fila de chamada e coleta)
Contents
Introduction
O Cisco Customer Voice Porta (CVP) fornece aplicações inteligentes de resposta de voz interativa (IVR) que podem ser acessadas por telefone. Há três tipos de implementações CVP:
-
Serviço independente
-
Controle de chamada CVP
-
Fila de chamada e coleta
Este documento descreve o fluxo de chamada da perspectiva do gateway de entrada IOS® baseado em H.323 em uma fila de chamada e implantação de coleta.
Na implantação Call Queue and Collect, o CVP interage com o Intelligent Contact Management (ICM) para tomar decisões de roteamento de chamadas. O ICM solicita que o CVP forneça o tratamento da Unidade de Resposta de Voz (URV) à chamada recebida para reproduzir prompts de menu e coletar dígitos para determinar o grupo de habilidades a ser selecionado. Quando o grupo de habilidades é identificado e um agente do grupo de habilidades está disponível, o ICM solicita ao CVP para conectar a chamada recebida ao telefone IP do agente via Cisco CallManager. Se o agente não estiver disponível, o ICM solicitará que o CVP forneça o tratamento da fila de chamadas (por exemplo, reproduzir um prompt de música em espera). O CVP fornece tratamento de URV ou fila de chamadas usando um Gateway VXML.

Exemplo de fluxo de chamada
Esta seção descreve o fluxo de chamada que resulta deste exemplo de configuração:
-
Uma chamada ISDN chega ao Gateway PSTN/VXML através do T1 PRI 1/0/0.
-
O IOS Gateway corresponde ao peer de discagem POTS 2 como o peer de discagem de entrada para esta chamada.
-
O IOS Gateway corresponde ao peer de discagem VoIP 1 como o peer de discagem de saída para esta chamada.
-
O IOS Gateway prepara o prefixo técnico "2#" para o número chamado e envia um ARQ para o Gatekeeper.
-
O gatekeeper roteia a chamada para o CVP.
-
O CVP atende a chamada e a conexão de mídia RTP é estabelecida entre o IOS Ingress Gateway e o CVP.
-
O CVP informa ao ICM sobre a nova chamada.
-
O ICM executa o script associado ao número chamado desta chamada.
-
O ICM solicita que o CVP forneça o tratamento da URV para reproduzir um prompt do menu (Main_Welcome_Menu.wav) e para coletar dígitos para identificar o grupo de habilidades.
-
1 para TAC
-
2 para vendas
O ICM também envia a Etiqueta ICM (8001112222) da URV de rede para o CVP.
-
-
O CVP envia uma solicitação ARQ (com destino = rótulo URV de rede) ao gatekeeper.
-
O gatekeeper fornece o endereço IP do VXML Gateway na resposta ACF.
-
O CVP envia uma configuração H225 para o VXML Gateway, que estabelece uma sessão VXML para o CVP. Consulte estes URLs para entender o VXML Gateway e o CVP, e o VXML Gateway e as interações do servidor ASR/TTS:
-
O CVP desconecta sua conexão de mídia RTP existente ao Gateway de entrada enviando o Estudo de caso dividido em temas vazio do H245.
-
O CVP estabelece uma conexão de mídia RTP entre o Gateway de entrada e o Gateway VXML.
-
O chamador PSTN digita o dígito "1" para selecionar o grupo de habilidades "TAC". O Gateway de entrada envia o DTMF via RTP NTE para o VXML Gateway 16) O Gateway VXML relata os dígitos para o CVP via VXML, que, em seguida, relata ao ICM.
-
O VXML Gateway relata os dígitos para o CVP via VXML, que depois reporta para o ICM.
-
Em seguida, o ICM encontra um agente disponível do grupo de habilidades selecionado e solicita ao CVP que roteie a chamada para o Agente enviando a Etiqueta do ICM (3#75001) do Agente.
-
O CVP desconecta a conexão de mídia RTP existente entre o Gateway de entrada e o Gateway VXML.
-
O CVP envia uma solicitação ARQ (com destino = rótulo do agente) ao gatekeeper.
-
O gatekeeper fornece o endereço IP do Cisco CallManager na resposta ACF.
-
O CVP envia uma configuração H225 para o Cisco CallManager, que estabelece uma chamada para o telefone IP do agente.
-
O CVP estabelece uma conexão de mídia RTP entre o Gateway de entrada e o Telefone do agente.
-
O chamador PSTN desliga a chamada após concluir a conversação com o agente.
-
O Gateway de entrada desconecta a chamada ao CVP e informa ao Gatekeeper sobre a terminação da chamada.
-
Em seguida, o CVP desconecta a chamada ao CCM.
