A SIP container is a web application server component that invokes the SIP action servlet and that interacts with the action servlet to process SIP requests.
The servlet container provides the network services over which requests and responses are received and sent. It decides which applications to invoke and in what order. The container also contains and manages servlets through their life cycle.
A SIP servlet container manages the network listener points on which it listens for incoming SIP traffic. A listener point is a combination of transport protocol, IP address, and port number. The SIP servlet container supports the transport protocols UDP, TCP, and TLS over TCP.
