Open publisher page 0 citations

Abstract

The Session Initiation Protocol (SIP) is an application-level control protocol for setting up, changing and terminating multimedia sessions between participants on IP data networks. In 1999 SIP was approved as an official standard and RFC2543 was published. SIP can enable a range of services, such as Internet telephony, multimedia conferencing, registration and redirection services, and simplifies connecting to VPNs. As its name implies, SIP is responsible for session signaling, a necessary exchange of messages to establish a communication session, be it voice, video or multimedia. In this paper we are going to provide information about the protocol functionality, and also we are going to describe the structure of the protocol.
