Abstract
Given a SIP call flow definition and WSDL extended with SIP/call flow interactions, a converged application integration (CAI) engine provides service-oriented application practitioners with an ability to reuse existing Web services integration techniques in a new converged application integration green space. The converged application integration engine “wraps” a pre-existing converged Web service/SIP or a SIP-only application, listens to application-specific signaling, and based on a supplied WSDL with SIP/call flow extensions, makes and accepts interaction requests using Web services. Given a SIP call flow definition, a WSDL extended with SIP/call flow interactions, and the converged application integration engine, a converged application execution (CAE) engine that greatly eases developing new converged applications. At runtime, the CAE engine “stitches” the signaling onto the decomposed servlet model by following the WSDL extended with SIP/call flow interactions. At appropriate binding points, the CAE engine invokes the listener callback interfaces.
