SIP

SIP, or Session Initiation Protocol, is a technology used to set up and manage communication sessions over the internet, such as voice calls, video chats, and conferencing. Think of it as a digital handshake that establishes, modifies, and ends these connections while ensuring they run smoothly. SIP is widely used in VoIP (Voice over Internet Protocol) systems, enabling efficient, flexible, and scalable communication without traditional phone networks. It handles signaling—the instructions and data needed to connect and maintain communication—making real-time conversations possible over the internet.
