GENERATING AND TRANSFORMING CALL CONTROL ELEMENTS, DIALOG ELEMENTS AND SESSION INITIATION PROTOCOL MESSAGES

摘要

Described are methods, systems, and apparatus, including computer program products for, in one example, generating call control and dialog elements for telephony service applications using a graphical user interface. A graphical user interface is provided. A module is generated, using the graphical user interface, for telephony applications. The module comprises a call control element and a dialog element. In another example, call control and dialog elements for telephony service applications are transformed from an intermediate language into a target language. The module is stored in an intermediate design file based on one or more intermediate languages. At least a portion of the intermediate design file is transformed into one or more target design files based on one or more target languages. In another example, a session initiation protocol message is transformed from a first format into a second format. A set of one or more instructions is associated with a rule. A session initiation protocol message is received. The first set of one or more instructions are determined to be applicable or not to the session initiation protocol message. The session initiation protocol message is transformed, using the first set of one or more instructions, into a target session initiation protocol message based on a second format.
