Session Initiation Protocol (SIP) is a common marketing term used for Voice over Internet Protocol for signaling and moderating the multi-media communication sessions such as voice calla, video calls and instant messaging. It was designed with the idea of supporting latest multimedia applications. It is an exceptional service that facilitate its users to route their private branch exchange (PBX) telephone system to the public switched telephone network (PSTN) for making calls.
SIP is meant for governing a message between end-points for its establishment, termination and even modification. This protocol is based on textual form which is designed to be independent of its transport protocol layers and efficiently runs on Transmission Control Protocol, Stream Control Transmission Protocol or User Datagram Protocol. It also encompasses of several components of HTTP (Hyper Text Transfer Protocol) and SMTP (Simple Mail Transfer Protocol).
This protocol works in juxtaposition of Session Description Protocol (SDP) for identifying the multimedia messages and makes use of Real-time Transport Protocol (RTP) and Secure Real-time Transport Protocol (SRTP). The SIP messages can also be transmitted securely by encrypting them with Transport Layer Security (TLS).
It describes the best transaction mechanism for regulating the exchanges between two users and reliably delivers the messages to the end-points. The ever-rising usage of internet for making free calls has raised the concern for security, thereby making SIP encryption a desirable necessity.
