Abstract

   The Session Initiation Protocol (SIP) is the subject of numerous
   specifications that have been produced by the IETF.  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.

1.  Introduction

   The Session Initiation Protocol (SIP) [RFC3261] is the subject of
   numerous specifications that have been produced by the IETF.  It can
   be difficult to locate the right document, or even to determine the
   set of Request for Comments (RFC) about SIP.  "Don't Panic!"  [HGTTG]
   This specification serves as a guide to the SIP RFC series.  It is a
   current snapshot of the specifications under the SIP umbrella at the
   time of publication.  It is anticipated that this document itself
   will be regularly updated as SIP specifications mature.  Furthermore,
   it references many specifications, which, at the time of publication
   of this document, were not yet finalized, and may eventually be
   completed or abandoned.  Therefore, the enumeration of specifications
   here is a work-in-progress and subject to change.

   For each specification, a paragraph or so description is included
   that summarizes the purpose of the specification.  Each specification
   also includes a letter that designates its category in the Standards
   Track [RFC2026].  These values are:

   S: Standards Track (Proposed Standard, Draft Standard, or Standard)

   E: Experimental

   B: Best Current Practice

   I: Informational

   The specifications are grouped together by topic.  The topics are:

   Core:  The SIP specifications that are expected to be utilized for
      each session or registration an endpoint participates in.

   Public Switched Telephone Network (PSTN) Interop:  Specifications
      related to interworking with the telephone network.

   General Purpose Infrastructure:  General purpose extensions to SIP,
      SDP (Session Description Protocol), and MIME, but ones that are
      not expected to always be used.

   NAT Traversal:  Specifications to deal with firewall and NAT
      traversal.

   Call Control Primitives:  Specifications for manipulating SIP dialogs
      and calls.
