    abstract =  {A large number of the services we wish to make possible for Internet telephony require fairly elaborate combinations of signalling operations, often in network devices, to complete. We want a simple and standardized way to create such services to make them easier to implement and deploy. This document describes an architecture for such a method, which we call a call processing language. It also outlines requirements for such a language.},
