Abstract

   The Session Initiation Protocol (SIP) is a text-based protocol for
   initiating and managing communication sessions.  The protocol can be
   compressed by using Signaling Compression (SigComp).  Similarly, the
   Session Description Protocol (SDP) is a text-based protocol intended
   for describing multimedia sessions for the purposes of session
   announcement, session invitation, and other forms of multimedia
   session initiation.  This memo defines the SIP/SDP-specific static
   dictionary that SigComp may use in order to achieve higher
   efficiency.  The dictionary is compression algorithm independent.
