Payload and Media Handling

In SIP (Session Initiation Protocol) communications, handling the payload and media correctly is crucial for establishing and maintaining high-quality communication sessions. This part delves into SIP header fields related to payload and media handling, ensuring that media streams are properly negotiated, encoded, and transmitted.
