Telephony is evolving at a frantic pace, critically relying on the development of services to offer a host of new functionalities. However, programming Internet telephony services requires an intimate knowledge of a variety of protocols and technologies, which can be a challenge for many programmers. Furthermore, because telephony is a resource heavily relied on, programmability of telephony platforms should not compromise their robustness. This paper presents an approach to creating telephony

We have developed a language, named Session Processing Language (SPL), that offers domain-specific constructs, abstracting over the intricacies of the underlying technologies. By design, SPL guarantees critical properties that cannot be verified in general-purpose languages. SPL relies on a Service Logic Execution Environment for SIP (SIP-SLEE) that introduces a design framework for service development based around the notion of session. SPL and SIP-SLEE have been implemented and they are now being used to develop and deploy real services, demonstrating the practical benefits of our approach. • What is the service programmer community (e.g., administrator, end-user)?
