(Optional) Setting SIP Stack Parameters
Context
The Session Initiation Protocol (SIP) is a text-based signaling protocol. SIP messages are classified into Request and Response messages. As an application layer protocol, SIP establishes, modifies, or terminates multimedia sessions and creates and controls multimedia sessions among two or more parties. SIP can work with specified protocols to complete session setup and media negotiation, such as Real-Time Transport Protocol (RTP), Real-Time Transport Control Protocol (RTCP), Session Description Protocol (SDP), Real-time Stream Protocol (RTSP), Domain Name System (DNS), Stream Control Transmission Protocol (SCTP), and Transmission Control Protocol (TCP).
