ABSTRACT: VoIP and the JAIN/SIP API

Voice over IP (VoIP) is all the rage these days. The underlying technology fueling its adoption and enabling interoperability is the Session Initiation Protocol (SIP). To expose these capabilities to Java Developers, the Java APIs for Integrated Networks (JAIN) group has defined the JAIN SIP API. This presentation will provide a deep understanding of this API and how to build VoIP enabled applications using it, including the call-flows and interaction models underlying the protocol. In addition to its VoIP applications, SIP also enables other collaboration capabilities such as instant messaging, and presence/availability. The presentation will delve into these capabilities and demonstrate how a developer could leverage them to build “convergent applications”
that enable much more than human-to-human collaboration.
