1.  Introduction

   The Session Description Protocol (SDP) [RFC4566] provides a means 
   for an offerer to describe the specifics of a session to an 
   answerer, and for the answerer to respond back with its session 
   specifics to the offerer.  These session specifics include offering 
   the codec or codecs to choose from, the specific IP address and port
   number the offerer wants to receive the RTP stream(s) on/at, the 
   particulars about the codecs the offerer wants considered or 
   mandated, and so on.
