O que é um telefone VoIP?

Um telefone VoIP, abreviação de Voice over Internet Protocol phone, é um dispositivo telefônico projetado especificamente para fazer e receber chamadas usando uma conexão de Internet em vez de uma linha telefônica convencional ou analógica. Os telefones VoIP convertem a voz do usuário em sinais digitais que são transmitidos pela Internet para alcançar outro telefone VoIP ou um número de telefone regular em qualquer lugar do mundo.


Os telefones VoIP podem variar em aparência e funcionalidade, muitas vezes se assemelhando a telefones de mesa tradicionais, mas com recursos adicionais habilitados pela conectividade com a internet. Eles têm hardware e software integrados que suportam protocolos de telefonia IP, permitindo que eles se registrem com um provedor de serviços VoIP e se comuniquem com outros endpoints IP.


Algumas características principais de um telefone VoIP incluem:


Chamadas pela Internet: em vez de depender da Rede Telefônica Pública Comutada (PSTN), os telefones VoIP usam a Internet de banda larga para rotear chamadas, reduzindo significativamente os custos de chamadas de longa distância e internacionais.


Recursos avançados: os telefones VoIP geralmente vêm com uma variedade de recursos que não são padrão em telefones tradicionais, como transcrição de correio de voz para e-mail, encaminhamento de chamadas, videoconferência, chamada em espera, identificação de chamadas e muito mais.


Compatibilidade com SIP: Muitos telefones VoIP usam o Session Initiation Protocol (SIP) para iniciar, manter e encerrar sessões multimídia. Este protocolo permite a interoperabilidade entre diferentes sistemas VoIP.


Power Over Ethernet (PoE): alguns telefones VoIP podem obter energia diretamente de um cabo Ethernet, simplificando a instalação e reduzindo a necessidade de tomadas elétricas separadas.

Mobilidade: a tecnologia VoIP também permite softphones – telefones baseados em software que transformam computadores, smartphones ou tablets em terminais VoIP.


Em resumo, um telefone VoIP é uma ferramenta de comunicação moderna que aproveita o poder da internet para fornecer serviços de comunicação de voz, geralmente a custos mais baixos e com maior flexibilidade em comparação aos telefones fixos tradicionais.
