Abstract: Systems and methods, including computer executable instructions, are provided for telephony service chaining. One method includes invoking a first application in a telephony session. The method includes retrieving a session context associated with the first application and using the session context an input to invoke a second application in the telephony session.

Abstract: Systems and methods are provided for coordinating telephony and web services. One method embodiment includes defining a call control XML (ccXML) element associated with accessing a web service application. The method includes extracting a session identification (ID) from a ccXML action in a telephony session. The session ID is used to store and retrieve session context in a context repository. A web service application is invoked using the session ID to coordinate events and context between the telephony session and the web service application.
