SIP (Session Initiation Protocol) IDL

Session Initiation Protocol (SIP) is a communication protocol used to initiate, manage, and terminate voice and video calls over the internet. SIP IDL (Interface Definition Language) helps define how different software components communicate within SIP systems. Essentially, it provides a structured way to describe the functions and data types that a SIP application can use, allowing developers to create compatible and interoperable tools. In simpler terms, SIP enables online calling, while SIP IDL ensures that different parts of the system can work together smoothly.
