RESUMO

This dissertation deals with modeling and development of Voice over IP (VoIP) system for multiplatform, using the SIP protocol to accomplish the session. The Session Initiation Protocol (SIP), used in the development of this system, is a protocol for creating, modifying and terminating calls between two or more participants, and it has received great support of the communications community. The RT-DSPhone system was developed for Linux and µClinux, which is a operating system for embedded system. The RT-DSPhone system was developed using the C language, the APIs of oSIP library, and tools for embedded systems, for the creation of a robust and flexible communication system. It is also described the architecture and operation of the SIP protocol used in the development of the RT-DSPhone signaling. The development of a system that allows the creation, control and finalization of multimedia sessions between two users through the SIP protocol is also detailed. Finally, some tests are carried out in order to evaluate the interoperability capacity of the developed system
