The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. SIP is text-encoded and highly extensible and may be extended to accommodate features and services such as call control services, mobility, interoperability with existing telephony systems.
