1.  Introduction

   The term "Voice over IP Peering" (VoIP Peering) has historically been
   used to describe a wide variety of practices pertaining to the
   interconnection of service provider networks and to the delivery of
   Session Initiation Protocol (SIP [2]) call termination over those
   interconnections.

   The discussion of these interconnections has at times been confused
   by the fact that the term "peering" is used in various contexts to
   describe interconnection at different levels in a protocol stack.
   Session Peering for Multimedia Interconnect focuses on how to
   identify and route real-time sessions (such as VoIP calls) at the
   session layer, and it does not (necessarily) cover the exchange of
