What is Session Initiation Protocol (SIP)?
Session Initiation Protocol (SIP) is a signaling protocol that you can use in a variety of important multimedia applications popular today, such as voice over IP (VOIP) and instant messaging. It allows for the initiation, maintenance and termination of real-time sessions that transmit voice, video and text messages.
SIP defines both the format of messages exchanged between parties as well as the sequence of communication that occurs between them. You use the protocol in conjunction with a variety of other protocols, such as the Session Description Protocol (SDP), which negotiates the media type and its parameters and sets up the media.
SIP functions independently of transport layer protocols. This means that you use it with the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP) and the Stream Control Transmission Protocol (SCTP). If you require secure transmissions, you can encrypt SIP messages with Transport Layer Security (TLS).
