Abstract

   This document defines a bi-directional protocol mapping for the

Internet-Draft       SIP-XMPP Interworking: Presence         August 2013

1.  Introduction

   In order to help ensure interworking between presence systems that
   conform to the instant message / presence requirements [RFC2779], it
   is important to clearly define protocol mappings between such
   systems.  Within the IETF, work has proceeded on two presence
   technologies:

   o  Various extensions to the Session Initiation Protocol ([RFC3261])
      for instant messaging, as developed within the SIP for Instant
