It can be difficult to locate the right document, or even to determine the set of Request for Comments (RFC) about SIP. This specification serves as a guide to the SIP RFC series. It lists a current snapshot of the specifications under the SIP umbrella, briefly summarizes each, and groups them into categories. This memo provides information for the Internet community.",
