Use Session Initiation Protocol to provide multimedia and interactive services

Follow these procedures for creating SIP applications and configuring the SIP container.

Overview

Session Initiation Protocol (SIP) is used to establish, modify, and terminate multimedia IP sessions including IP telephony, presence, and instant messaging. A SIP application in WebSphere is a Java program that uses at least one Session Initiation Protocol (SIP) servlet. A SIP servlet is a Java-based application component that is managed by a SIP servlet container.

The servlet container is a part of an application server that provides the network services over which requests and responses are received and sent. The servlet container decides which applications to invoke and in what order. A servlet container also contains and manages a servlet through its lifecycle.

SIP servlet containers can employ SIP proxy servers as surrogates to handle load balancing and security issues. For more information about the SIP proxy server, see: Session Initiation Protocol proxy server.

This topic is divided into the following subsections:

• Configure the SIP container: Information and instructions for configuring SIP container properties and timers.

• Developing SIP applications: Reference information for developers.

• Deploying SIP applications: Information for installing, starting, and stopping, your applications.

• Securing SIP applications: Instructions for enabling security providers and setting up a trust association interceptor (TAI).

• Tracing a SIP container: Troubleshoot SIP applications through traces on the SIP container.
