PJSIP (Session Initiation Protocol) is a protocol used for initiating, managing, and terminating real-time communication sessions such as voice calls, video calls, and instant messaging. Here are some common PJSIP commands
1. `INVITE` - This command is used to initiate an INVITE request, which is a message sent from one endpoint to another to propose a new session. The INVITE request includes information such as the type of session being proposed (voice call, video call, etc.), the media streams that will be used, and any other relevant parameters. 2. `ANSWER` - This command is used to respond to an INVITE request by accepting or rejecting the proposal. If the answer is accepted, a new session is established, and the two endpoints can begin communicating with each other. 3. `HANGUP` - This command is used to terminate an ongoing session. It can be initiated by either endpoint and signals the end of the communication session. 4. `BYE` - This command is similar to HANGUP, but it is used to indicate that one endpoint is leaving the session gracefully. The BYE message is sent before
