In telecommunications, Session Initiation Protocol (SIP) trunks have emerged as a game-changer, revolutionizing the way businesses handle their communication needs. But what exactly is a SIP trunk, and how does it work?
Understanding the Basics
Before we dive into unraveling SIP trunks, let’s grasp the basics. SIP, or Session Initiation Protocol, is a signaling protocol widely used for initiating, maintaining, modifying, and terminating real-time sessions that involve video, voice, messaging, and other communications applications and services. Now, imagine SIP as the maestro orchestrating the communication symphony.
A SIP trunk, on the other hand, is the virtual version of the traditional analog phone line. It acts as the conduit that enables the flow of SIP communication between an organization’s Private Branch Exchange (PBX) and the Internet Telephony Service Provider (ITSP).
