1. Initiation: The caller sends a SIP request to initiate a session.
2. Invitation: The request is forwarded to the recipient, who receives an invitation to join the session.
3. Acknowledgement: The recipient accepts the invitation, and both parties acknowledge the session initiation.
4. Communication: The session is established, allowing communication to take place.
5. Termination: Either party can send a request to terminate the session when finished.

• User Agents (UAs): These are endpoints in a SIP network, which can be hardware devices like phones or software applications.
• Registrar: A server that accepts registration requests from UAs and updates its location database with the information.
