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.
This is part III where we create a SIP trapezoid with Repro SIP proxies to go over a sample call to discuss how the requests are sent out and what responses are expected per RFC 3261.
