The document discusses Session Initiation Protocol (SIP) in 3 paragraphs:
1) SIP is a signaling protocol standardized by IETF to establish, maintain, and terminate multimedia sessions like voice, video, and messaging over IP networks.
2) SIP uses text-based messages similar to HTTP with request/response formats. Messages have headers and bodies. Six main messages are defined to initialize, acknowledge, request capabilities, cancel initialization, and register IP addresses.
3) SIP signaling involves a three-way handshake to establish sessions via INVITE, response, and ACK messages. Sessions use temporary ports and are terminated with BYE messages. SIP addresses can be email, IP, phone numbers, and other identifiers.

The Session Initation Protocol (SIP) is a signaling
protocol for IP networks, which is standardized by IETF to establish, maintain, and terminate multimedia sessions. It uses for such sessions include voice, video, chat and instant messaging, as well as interactive games and virtual reality. The SIP protocol is increasingly being used to provide Voice over IP, Presence and Instant Messaging in Next Generation Networks, and being mandated for many new applications, including 3G telephony. SIP MESSAGE
Text based protocol similar to HTTP.
Similar to HTTP, SIP uses messages in a request/response. Each message has header and body SIX messages are defined as in figure below. -used by the -a message -used to -used to -used to -used by SIP caller to with which terminated an request cancel user agent to initialize the caller established information alreaady register session acknowledges session about the started current IP

An Email address SIP: dhanyhamsi@ptsb.edu.my 2. An IP address SIP: dhanyhamsi @ 201.23.45.78 3. A telephone number SIP: dhanyhamsi@+06-56334 SIP SIGNALING - The SIP signaling process is simply a series of requests and acknowledgements between software agents-known as ‘user agents’-acting on behalf of a user or in animate computer equipment - A simple example is given which shows the SIP message flows involved in established and clearing down a multimedia call, say voice and text, between users associated with computer terminals A and B. SIP SESSION i) Establishing -Establishing a session requires a three-way handshake. The caller sends an INVITE message, using TCP or UDP to begin the communication. If the caller is willing to start, he/she sends a reply message. To confirm that a reply code has been received the caller sends an ACK message. ii) Communicating -After the session has been established the caller and caller can communicate by using two temporary ports. iii) Terminating -The session can be terminated with a BYE message sent by either party Thank You!
