Voz sobre IP (VoIP) é um nome genérico para serviços, sistemas e tecnologia para telefonia em uma rede IP. Também é conhecida como telefonia via Internet e telefonia IP (Internet Protocol). O software cliente de telefone pela Internet atraiu a atenção quando apareceu pela primeira vez em 1995. Desde então, o VoIP amadureceu rapidamente e se tornou uma tecnologia prática, impulsionada pela popularização e pelo rápido desenvolvimento da Internet. O tráfego da rede IP já excede o tráfego da rede telefónica e espera-se que aumente ainda mais nos próximos anos. No futuro, a rede telefónica será integrada na rede IP e a telefonia passará a ser inteiramente VoIP. Existem três expectativas para VoIP. O primeiro é o serviço telefônico barato. A segunda expectativa é de serviços integrados de telefonia e rede IP, como um sistema CTI (Computer Telephony Integration), no qual haja interoperabilidade com diversas aplicações da Internet, como e-mail e retorno de chamada pela Web, para serviços de comunicação de maior conveniência, em vez de simples substituição do telefone. A terceira expectativa é a de uma plataforma que forneça comunicação de voz de alta qualidade, comunicação multicast e outros serviços de voz aprimorados que tenham um alto grau de liberdade. No entanto, muitos problemas ainda precisam ser superados antes que o sistema VoIP seja concretizado. Os principais problemas são a transmissão de voz em tempo real que permite uma conversa tranquila, o controle de sessão para prestação de diversos serviços e a proposta de novos serviços. Neste artigo, damos uma visão geral do VoIP e dos problemas que devem ser resolvidos para realizá-lo e propomos algumas soluções em relação ao controle de fluxo e aplicações. Também descrevemos o controle de sessão e outros tópicos que estão sendo discutidos em fóruns de padronização.

Abstract: Voice over IP (VoIP) is a generic name for services, systems and technology for telephony over an IP network. It is also referred to as Internet telephony and IP (Internet Protocol) telephony. Internet telephone client software attracted attention when it first appeared in 1995. Since that, VoIP has rapidly matured into a practical technology, propelled by the popularization and rapid development of the Internet. IP network traffic already exceeds telephone network traffic and is expected to further increase several-fold in the next few years. In future, the telephone network will be integrated into the IP network and telephony will become entirely VoIP. There are three expectations for VoIP. The first is inexpensive telephone service. The second expectation is for integrated telephony and IP network services such as a CTI (Computer Telephony Integration) system in which there is interworking with various Internet applications, such as e-mail and Web call-back for communication services of greater convenience rather than simple replacement of the telephone. The third expectation is for a platform for providing high-quality voice communication, multicast communication, and other such enhanced voice services that have a high degree of freedom. However, many problems remain to be overcome before the VoIP System is realized. The main problems are real-time transmission of voice that allows a smooth conversation, session control for providing a variety of services, and the proposal of new services. In this paper, we give an overview of VoIP and the problems that must be solved in order to realize it and propose some solutions regarding stream control and applications. We also describe session control and other topics that are being discussed in standardization forums.
