Guia de configurações de tempo do telefone SIP industrial (incluindo sincronização de tempo de rede)

Introdução

Visão geral

Este guia explica como sincronizar a hora exibida no telefone.

Modelos aplicáveis

Todos os nossos modelos de telefone suportam este recurso (o X5U é usado neste artigo como exemplo).

Pré-requisitos

① Um telefone, conectado ao switch e capaz de obter um endereço IP.
② Um computador para configuração, conectado ao mesmo switch que o telefone para garantir a comunicação de rede entre o computador e o telefone.

Etapas de configuração

Método 1: Sincronizar a hora a partir do servidor SIP

Na tela LCD do telefone, toque em “Menu” — “Status” para verificar o endereço IP do telefone.

Faça login na interface web do telefone abrindo um navegador no computador e digitando o endereço IP do telefone na barra de endereços.
Interface web
Após fazer login na interface web, vá para “Linha” - “SIP” - “Configurações avançadas” e ative “Sincronizar hora do telefone”.
Sincronizar hora do telefone
Quando a hora é sincronizada através do registro SIP, o telefone usa o campo Data na resposta 200 OK do servidor como referência de hora e, em seguida, ajusta-a de acordo com o fuso horário configurado no telefone para exibição. Quando a sincronização de hora SIP está ativada, as sincronizações SNTP e DHCP são desativadas automaticamente. Este método requer que o servidor SIP inclua um campo Data na resposta 200 OK.

Método 2: Sincronizar a hora da rede

Faça login na interface web do telefone, depois vá para “Configurações do telefone” - “Hora/Data” e configure as opções conforme mostrado na Figura 1 abaixo.
Usar SNTP para sincronização de hora significa configurar os “Endereços do servidor de horário primário/secundário”. Eles podem ser definidos como um endereço IP ou nome de domínio. Após a inicialização, o telefone consulta o servidor primário pela hora atual. Se o servidor primário não responder, ele muda automaticamente para o servidor secundário. Durante a operação, o telefone atualiza a hora periodicamente. Este método requer que o endereço do servidor SNTP seja pré-configurado.

Método 3: Sincronizar a hora via DHCP

Faça login na interface web do telefone, depois vá para “Configurações do telefone” - “Hora/Data” e configure as opções conforme mostrado na Figura 2 abaixo.
Para usar este método, tanto “Usar sincronização de hora SNTP” deve estar ativado e o modo de rede deve ser definido como DHCP. Neste modo, o telefone obtém seu endereço IP via DHCP na inicialização. Quando recebe a resposta ACK do servidor, ele lê o endereço do servidor SNTP da Opção 42 e o escreve nos campos “Endereços do servidor de horário primário/secundário”, depois sincroniza a hora via SNTP. Este método requer que o servidor DHCP suporte a Opção 42.
