What is SIP? Session Initiation Protocol

The Session Initiation Protocol is an application layer protocol that is used to control single-media or multimedia communication sessions between two or more endpoints on IP networks. The SIP Protocol was developed by the SIPCORE working group of the Internet Engineering Task Force, and it is defined in RFC 3261. SIP complements the other communication protocols like Real-Time Transport Protocol and Real-Time Streaming Protocol. After knowing what SIP is, you should consider the installation of a SIP trunk because of its convenience.
