• Protocolo de sinalização usado para estabelecer, gerenciar e terminar sessões em uma rede IP

• Protocolo definido na RFC 3261

• Extendido em diversas outras RFCs

• Baseado em mensagens ASCII

• Equipamentos finais (Endpoints) são conhecidos como User Agents

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 11

• Mensagens SIP

• Pedidos e Respostas (Requests and Responses)

• Cabeçalhos (Headers)

• Negociação de Mídia

• Session Description Protocol - SDP

• Modelo Oferta/Resposta (Offer/Answer)

• Early Offer x Delayed Offer

• Early Media

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 12

• User Agent Clients (UAC) enviam Pedidos para os User Agent Servers (UAS)

• User Agent Servers enviam Respostas aos Pedidos

• A maioria dos dispositivos SIP são ao mesmo tempo UAC e UAS (ambos iniciam e aceitam Pedidos)

• Unified CM e CUBE são Back-to-Back User Agents (B2BUA)

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 13

• INVITE - Um usuário ou serviço está sendo convidado a participar de uma sessão SIP

• ACK - Confirma que um cliente recebeu uma Resposta final para um Pedido de INVITE

• BYE - Termina uma sessão existente; pode ser enviada por qualquer User Agent (em uma sessão de múltiplos usuários)

• CANCEL – Cancela Pedidos pendentes; não finaliza sessões que já foram aceitas

• OPTIONS - Pergunta as capabilities de um servidor (Também utilizado como Keep Alive)

• REGISTER - Registra o User Agent no Registrar Server do domínio

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 14

• INFO (RFC 2976) - para enviar mais informações em um diálogo já estabelecido

• PRACK (RFC 3262) - para confirmar o recebimento de uma Resposta provisória a um Pedido.

• SUBSCRIBE (RFC 3265) – para informar que quer ser notificado se um evento específico ocorrer.

• NOTIFY (RFC 3265) - para notificar um assinante que um evento específico ocorreu.

• UPDATE (RFC 3311) - para atualizar parâmetros antes de uma Resposta final ao INVITE.

• MESSAGE (RFC 3428) - Mensagens Instâneas SIP

• REFER (RFC 3515) - para remeter um User Agent para se comunicar com outro User Agent

• PUBLISH (RFC 3903) - para enviar informações sobre status de um User Agent a um Presence Server

• SIP utiliza o Session Description Protocol (SDP) (RFC 4566/3266/2327) para passar as informações de mídia.

• SIP usa o modelo Oferta/Resposta (Offer/Answer) descrito na RFC 3264 para negociar a mídia utilizando o SDP.

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 23

• Um User Agent envia uma Oferta de SDP contendo toda as opções que pode negociar.

• SDP contém M linhas para cada media stream sendo negociado (Ex: áudio, vídeo, canal de conteúdo, etc)

• O outro User Agent envia uma Resposta de SDP que contém as mesmas ou parte das mesmas opções recebidas no pedido inicial.

• De acordo com a RFC 3264, “Para cada "m=" na Oferta, DEVE conter uma linha correspondente "m=" na Resposta. A Resposta deve conter o mesmo número de linhas "m=" contidas na Oferta.

• O User Agent Client pode enviar uma Oferta de SDP dentro do INVITE - isto é denominado Early Offer.

• O User Agent Server pode enviar uma Oferta de SDP em uma mensagem de Resposta caso o INVITE não contenha uma Oferta de SDP - isto é denominado Delayed Offer.

• Para o Early Offer, a Resposta de SDP é enviada dentro de uma mensagem de Resposta ao INVITE.

• Para o Delayed Offer, a Reposta de SDP é enviada dentro da mensagem de Pedido ACK.

• Delayed Offer não estabelece a mídia até a mensagem de 200 OK (ligação atendida)

• Caso a mídia seja requerida antes da ligação ser atendida, SIP executa o processo conhecido como Early Media

• Com o Early Media em uma ligação Delayed Offer, a Oferta de SDP é originada pelo User Agent Server dentro de uma mensagem de resposta Provisória (Ex: 183 Session Progress)

• O User Agent Client envia a Resposta de SDP dentro de uma mensagem de pedido PRACK (Definida na RFC 3262)

• Qualquer User Agent envolvido em uma ligação pode enviar um Re-INVITE em um diálogo existente para renegociar parâmetros de uma ligação.

• Não é possível enviar um Re-INVITE antes que uma mensagem de INVITE tenha recebido uma Resposta final.

• O método UPDATE também pode ser usado para renegociar, porém antes que uma Resposta final tenha sido recebida.

• Unified CM / SME Tools:

Real Time Monitoring Tool -> Session Trace

• TranslatorX

• Wireshark

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 42

• Permite procurar por uma chamada com base no número de origem ou de destino

• Não depende de CDRs

• Session trace apenas rastreia as sessões SIP, de forma detalhada

• Exibe as mensagens SIP completas e originais

• Utiliza tags de correlação para incluir todos os call legs relacionados com a chamada selecionada

• Só pode ser usado para chamadas cujos traces ainda estão no servidor (CUCM 9.0 permite visualizar traces que foram arquivados fora do servidor)

• Ambos, CUCM e IOS, fornecem mecanismo para coletar uma captura de pacotes

• Como realizar uma coleta de pacote?

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 61

• Acesse CUCM via SSH

• Para começar a captura aplique o comando:

utils network capture file [file name] size all count 100000

Example:

utils network capture file CUCMCapture size all count 100000

• Se este comando é aplicado várias vezes com o mesmo nome de arquivo, CUCM irá automaticamente renomear o arquivo com “_” e o seguinte número.

• A captura parará depois que 100000 pacotes forem coletados ou se CTRL+C é pressionado.

• Executar o teste recriando o problema.

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 62

• Faça download da captura usando um dos métodos abaixo:

• Se é CUCM 7.X ou versões seguintes, colete os arquivos de log via RTMT selecionando o serviço “Pacture Capture Logs” (listado na segunda página de serviços) durante o período da captura.

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 63

• Se é CUCM 6.X ou versões anteriores, aplique o comando abaixo para enviar a captura para um servidor de SFTP:

file get activelog /platform/cli/[file name].cap

Example:

file get activelog /platform/cli/CUCMCapture.cap

© 2011 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 64

• IP traffic Export feature permite capturar pacotes na interface de um roteador.

• Configuração:

• Utilização:

ip traffic-export profile CUBE_Debug mode capture

bidirectional

incoming access-list 101

outgoing access-list 101

interface GigabitEthernet0/0

ip traffic-export apply CUBE_Debug size 10000000
