A Session Initiation Protocol (SIP) Call Flow is a causal sequence of messages that is exchanged between interacting SIP entities. We present a novel test system for SIP based on the notion of XML Protocol Templates, of SIP call flows. These templates can be pattern matched against incoming messages and augmented with general purpose code to implement specific protocol responses. This architecture allows test systems to be easily scripted, modifed and composed. We describe these techniques in the construction of a SIP web-based interoperability tester (SIP-WIT) and comment on their potential more general use for scripting SIP services.
