Session Initiation Protocol (SIP)

The Session Initiation Protocol (SIP) is a technology used to start, manage, and end communication sessions over the internet, such as phone calls or video chats. It acts like a digital receptionist, helping devices locate each other, establish a connection, and coordinate how data flows during the conversation. SIP ensures that different services—like voice over IP (VoIP) calls or video conferencing—can work seamlessly across various networks and devices. Essentially, SIP manages the setup and teardown of real-time communication sessions, enabling flexible and efficient digital conversations.
