Este documento estuda uma rede VoIP com uma topologia da duas zonas controladas por dois gatekeepers Cisco com o um gateway Cisco em cada zona. O objetivo deste original é fornecer uma configuração básica que permita que o usuário evite alguns problemas comuns e crie uma base confiável para uma rede baseada em gatekeepers. Este documento inclui informações técnicas de fundo sobre recursos configurados, diretrizes de projeto e verificação básica e estratégias de Troubleshooting.
É importante observar que na configuração abaixo os quatro roteadores estão localizados na mesma LAN. No entanto, em sua real topologia, todos os dispositivos podem estar em partes diferentes de sua rede.
Para obter mais informações sobre convenções de documento, consulte as Convenções de dicas técnicas Cisco.
Não existem requisitos específicos para este documento.
Essas configurações foram testadas com este equipamento:
Quatro Cisco 2600s com Cisco IOS® Software Release 12.2.8.5 ENTERPRISE PLUS/H323 MCM
As informações neste documento foram criadas a partir de dispositivos em um ambiente de laboratório específico. All of the devices used in this document started with a cleared (default) configuration. Se você trabalhar em uma rede ativa, certifique-se de que entende o impacto potencial de qualquer comando antes de utilizá-lo.
Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.
Observação: para encontrar informações adicionais sobre os comandos usados neste documento, use a ferramenta Command Lookup Tool (somente clientes registrados).
Há várias condições a serem atendidas para que o Gateway possa obter a resolução correta de endereços do Gatekeeper.
Há dois pontos importantes a serem verificados:
Todos os gateways devem ser registrados em gatekeepers correspondentes.
Todos os Gatekeepers devem ter o plano de discagem correto.
O registro bem-sucedido é a primeira etapa obrigatória. Estes fatores adicionais devem ser tidos em conta:
Se o Gateway tiver interfaces FXS (Foreign Exchange Station) e, em seguida, nos correspondentes de discagem POTS (Plain Old Telephone Service), adicione o comando no register e164. Isso evita o problema com o registro do Gateway descrito na ID de bug da Cisco CSCdw60626 (somente clientes registrados) . Em vez de registro direto de porta FXS com números e164, é possível adicionar um prefixo de zona para o Gateway e basear as decisões de roteamento nos prefixos de zona.
Geralmente, é preferível definir um prefixo de tecnologia para o Gateway. Embora a presença dos prefixos de tecnologia afete predominantemente o roteamento de chamadas, também é desejável um registro confiável.
Para obter mais informações sobre problemas de registro de Gateway para Gatekeeper, consulte Troubleshooting de Problemas de Registro de Gatekeeper.
Para roteamento de chamadas confiável, todos os gateways devem ser registrados com algum prefixo de tecnologia. A finalidade do prefixo de tecnologia é distinguir entre diferentes tipos de chamadas e os tipos correspondentes de gateways. Assim, embora seja possível usar o prefixo de tecnologia para decisões de roteamento, a melhor prática é usar o prefixo de tecnologia para distinguir o tipo de chamada e rota com base nos prefixos de zona.Com essa abordagem, todos os Gateways VoIP podem ser configurados com o mesmo prefixo de tecnologia (por exemplo, 1#*, como no exemplo apresentado neste documento).
É preferível configurar explicitamente o gateway principal para o prefixo de zona.
Vincule a sinalização H.323 a um endereço IP específico no Cisco IOS Gateway ou roteador. Quando o Cisco IOS Gateway tem várias interfaces IP ativas, algumas das mensagens H.323 podem ser originadas de um endereço IP e outras partes dele podem referenciar um endereço de origem diferente. O comando h323-gateway voip bind srcaddr é necessário se a interface de loopback for usada para identificar o Gateway ou se houver um firewall e servidores de contabilidade na rede. Este comando foi introduzido no Cisco IOS Software Release 12.1.2T e está documentado em Configuração do Suporte H.323 para Interfaces Virtuais.
Para obter mais informações sobre o roteamento de chamadas do Gatekeeper, consulte Entendendo o Roteamento de Chamadas do Gatekeeper H.323 do Cisco IOS.
Este documento utiliza a instalação de rede mostrada no diagrama abaixo.
Este documento utiliza estas configurações.
A verificação das configurações do Gatekeeper e do Gateway é uma parte importante da solução de problemas de Gateway para Gatekeeper. Para simplificar a compreensão das configurações, todos os comandos de configuração não relacionados foram removidos.

show gateway — Exibe o status de registro do Gateway.
show gatekeeper endpoints — Exibe todos os Gateways registrados no Gatekeeper.
show gatekeeper zone prefix — Exibe todos os prefixos de zona configurados no Gatekeeper.
show gatekeeper call — Mostra as chamadas ativas processadas pelo Gatekeeper.

Conceitos Básicos de Troubleshooting e Depuração de Chamadas VoIP
Referência aos Comandos de Fax, Vídeo e Voz do Cisco IOS, Versão 12.2
Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.
Para solucionar problemas, verifique vários pontos vitais:
Todos os gateways devem ser registrados com os Gatekeepers correspondentes.
Os gateways devem ter o plano de discagem correto (peers de discagem configurados).
Os gatekeepers devem ter o plano de discagem correto (prefixos de zona configurados).
As etapas descritas em Noções Básicas sobre Troubleshooting e Depuração de Chamadas VoIP complementam a saída dos comandos debug e show relacionados à interação Gateway-to-Gatekeeper e devem ser usadas para destacar os problemas de voz relacionados a outros subsistemas do Cisco IOS. As saídas de exemplo dos comandos show destacam as etapas acima e a saída debug mostra a sequência de mensagens RAS e H225 em todos os quatro roteadores.
Observação: o comando debug h225 asn1 gera uma saída muito grande, portanto, deve ser usado com muito cuidado. Algumas saídas desnecessárias foram excluídas dos comandos debug abaixo.
Observação: antes de emitir comandos debug, consulte Informações Importantes sobre Comandos Debug.
