SIP (Session Initiation Protocol)

SIP (Session Initiation Protocol) is a signaling technology used to set up, manage, and terminate communication sessions like phone calls, video chats, and online meetings over the internet. It acts as the communication "orchestra conductor," signaling devices and systems to establish a connection, coordinate the transfer of data, and end the session when finished. SIP is flexible and supports various media types, enabling seamless multimedia communication between different devices and platforms. It’s widely used in Voice over IP (VoIP) services and online conferencing to enable real-time, interactive conversations.
