A SIP (Session Initiation Protocol) server is a critical component in voice over IP (VoIP) communications that manages the setup, maintenance, and termination of calls between endpoints. It acts as a registrar, proxy, and sometimes a redirect server, facilitating the routing of SIP messages between devices and ensuring proper call handling. The SIP server's information typically includes its IP address, port number, and transport protocol, which are necessary for configuring SIP clients to communicate with it.
