Abstract

   This memo documents a process intended to apply architectural
   discipline to the future development of the Session Initiation
   Protocol (SIP).  There have been concerns with regards to new SIP
   proposals.  Specifically, that the addition of new SIP features can
   be damaging towards security and/or greatly increase the complexity
   of the protocol.  The Transport Area directors, along with the SIP
   and Session Initiation Proposal Investigation (SIPPING) working group
   chairs, have provided suggestions for SIP modifications and
   extensions.

1. Terminology
