Servlet model for media rich applications

摘要

A media rich SIP servlet is enabled using a media control layer and a conventional SIP Servlet container. The media rich SIP servlet provides a media control API that can be used by SIP-based application developers to incorporate media rich functions into SIP-based applications. The media rich SIP servlet includes an advanced call control API, which enhances the basic call control functions provided by a SIP servlet. The media rich SIP servlet provides call and media control primitives for use by SIP servlet based applications, thereby enabling media rich SIP servlet based applications.
