Introduction

Este documento fornece um exemplo de configuração para usuários remotos fazendo chamadas usando um dos métodos a seguir. Em cada caso, a rechamada é executada com o uso de uma chamada V.110.

  • Usuários conectando o 3640 via GSM e requisitando retorno da chamada.

  • Os usuários conectando o 3640 por meio de um modem e solicitando retorno de chamada.

  • Usuários se conectando ao 3640 via ISDN (dados) e solicitando um retorno de chamada.

Observação: a autenticação, autorização e contabilização (AAA) é configurada no roteador por padrão. Você também deve criar um usuário para fazer login.

Neste exemplo, também definimos a autenticação PPP (Point-to-Point Protocol) para chamada e chamada. Alteramos o script para configurar o modem para V.110 o tempo todo e para permitir que os usuários escolham seu método (modem ou GSM). Dependendo do método escolhido, os usuários devem:

  • use ZDTxxx no número de chamada de retorno (para modem).

  • use Dlxxxx no número de rechamada (para GSM).

Prerequisites

Requirements

Não existem requisitos específicos para este documento.

Componentes Utilizados

Verificar

Esta seção fornece informações que você pode usar para confirmar se sua configuração está funcionando adequadamente.

A Output Interpreter Tool (somente clientes registrados) oferece suporte a determinados comandos show, o que permite exibir uma análise da saída do comando show.

  • show ip route????exibe o conteúdo da tabela de roteamento IP

Troubleshoot

Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.

Observação: antes de emitir os comandos debug, consulte Informações importantes sobre comandos debug.

  • debug modem —para observar a atividade da linha do modem em um servidor de acesso.

  • debug dialer events — exibe informações de debugação sobre os pacotes recebidos em uma interface de discador.

  • debug ppp authentication —exibe mensagens do protocolo de autenticação, incluindo trocas de pacotes CHAP (Challenge Authentication Protocol Protocolo de Autenticação de Desafio) e PAP (Password Authentication Protocol Protocolo de Autenticação de Senha).

  • debug ppp cbcp —exibe erros de protocolo e estatísticas associadas às negociações de conexão PPP usando o Protocolo de Controle de Chamada da Microsoft (MSCB - Microsoft Callback Control Protocol).

  • debug isdn q931 — exibe informações sobre configuração de chamada e subdivisão de conexões de rede ISDN (Camada 3) entre o roteador local (lado do usuário) e a rede.

  • debug chat —verifica se o script de bate-papo está funcionando corretamente.

  • debug callback —exibe eventos de retorno de chamada quando o roteador está usando um modem e um script de bate-papo para retornar a chamada em uma linha de terminal.
