RFC 3261 Simplified: Session Initiation Protocol Part-Four

RFC 3261, Session Initiation Protocol, is a very dry document. It is hard to read and hard to understand. In this RFC 3261 Simplified series, we are going to use examples and analogies to explain RFC 3261, Session Initiation Protocol, in a language that will appeal to a wide spectrum of audience. In part IV, we focus on the UAS side and go over the initial method independent steps a UAS follows to process a request; Authentication, Method Inspection, Header Inspection, Content Processing, and Applying Extensions.
