Session Initiation Protocol (SIP) is a communication protocol used for initiating, maintaining, and terminating real-time sessions that involve video, voice, messaging, and other communications applications. It works by sending messages between endpoints, which can be phones, computers, or other devices, to establish and manage the connection. SIP is crucial in the telecom and network management industry because it enables seamless and efficient communication across different platforms and devices, ensuring interoperability and flexibility in modern communication systems.
Overview of SIP
SIP, or Session Initiation Protocol, is a signaling protocol used to initiate, maintain, and terminate multimedia communication sessions. It is widely adopted for its flexibility and interoperability, allowing seamless integration across various devices and platforms. SIP's efficiency in managing real-time communications makes it a cornerstone in modern telecom infrastructure.
