The scope of telephony is significantly broadening, providing users with a variety of communication modes, including presence status, instant messaging and videoconferencing. Furthermore, telephony is being increasingly combined with a number of non-telephony, heterogeneous resources, consisting of software entities, such as Web services, and hardware entities, such as location-tracking devices. This heterogeneity, compounded with the intricacies of underlying technologies, make the programming

To do so, we introduce a declarative language over Java to define the entities of a target telephony application area. This definition is passed to a generator to produce a Java programming framework, dedicated to the application area. The generated frameworks provide service discovery and high-level communication mechanisms. These mechanisms are automatically mapped into SIP, making our approach compatible with existing SIP infrastructures and entities. Our work is implemented and has been validated on various advanced telephony applications.
