Use Session Initiation Protocol to provide multimedia and interactive services

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

This topic is divided into the following subsections:

• Configure the SIP container: Information and instructions for configuring SIP container properties and timers.
• Develop SIP applications: Reference information for developers.
• Deploy SIP applications: Information for installing, starting, and stopping, the applications.
• Secure SIP applications: Instructions for enabling security providers and setting up a TAI.
• Tracing a SIP container: Troubleshoot SIP applications through traces on the SIP container.

Subtopics

• SIP in WAS
  WebSphere Application Server delivers rich SIP functionality throughout its infrastructure.
• SIP applications
  A SIP application is a Java program that uses at least one SIP servlet.
• SIP container
  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.
• Configure the SIP container
  Configure the SIP container to adjust message response times or set a custom property.
• Develop SIP applications
  A SIP application is a set of SIP servlets packaged in a SIP application archive file (SAR).
• Deploy SIP applications
  Use the dmgr console to customize your SIP application installation
• Secure SIP applications
  We can apply digest authentication and Trust Association Interceptor (TAI) for a SIP application by applying LDAP security to the application.
• Tracing a SIP container
  We can trace a SIP container, starting either immediately or after the next server startup. This tracing writes a record of SIP events to a log file.
• Troubleshooting SIP applications
  We can use this topic to troubleshoot SIP applications.
• Tune SIP servlets for Linux
  This page describes preliminary SIP servlet tuning for Linux 2.6 kernel.
• SIP timer summary
  Request for Comments (RFC) 3261, "SIP: Session Initiation Protocol," specifies various timers that SIP uses.
