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).
The Inner Workings
Initiating the Call:
- When you pick up your desk phone to make a call, your PBX sends a request to the SIP trunk, signaling the initiation of the call.
Routing the Call:
- The SIP trunk then routes this request through the internet to the ITSP, which acts as the bridge connecting your internal communication system with the global network.
Interacting with the PSTN:
- If the call is destined for a traditional landline or mobile phone, the SIP trunk interacts with the Public Switched Telephone Network (PSTN) through the ITSP.
- During this journey, signals are converted between analog and digital as needed, ensuring seamless communication between different systems.
Completing the Connection:
- The call reaches its destination, and communication takes place. The SIP trunk continues to facilitate the exchange of information until the call is terminated.
