ABSTRACT
The growing utilization of Internet Broadband access is popularizing Instant Messaging services enhanced with Voice and Video. However, despite the existence of open and standardized signaling protocols, the most popular services still use proprietary protocols and clients, hindering the interoperability among the existent solutions. This paper presents the methodology of implementation and validation of Metaverse: an IP Telephony and Instant Messaging application compliant with the Internet Engineering Task Force (IETF) open specifications, allowing its interoperability with other standards adherent solutions.A crescente utilização de Internet Banda Larga vem popularizando os serviços de Mensagens Instantâneas com recursos de conversação via voz e vídeo sobre IP. Entretanto, apesar da existência de protocolos de sinalização abertos e padronizados, os serviços mais populares utilizam protocolos e clientes propriet´rios, impedindo a interoperabilidade entre as diversas soluções. Este artigo apresenta a metodologia de implementação e validação do Metaverse: uma aplicação de Telefonia IP e Mensagens Instantâneas totalmente aderente às especificações abertas do Internet Engineering Task Force (IETF), permitindo sua interoperabilidade com outras soluções aderentes aos padrões.
