Technical Summary

   This document describes bidirectional protocol mappings for the
   exchange of pressence information between SIP (Session Initiation
   Protocol) and XMPP (eXtensible Messaging and Presence Protocol)
   endpoints. RFC 7247 provided the basic architectural concepts for
   interworking between the two protocols, and this document is
   dedicated to describe to apply such concepts in the context of
   presence exchange.

   RFC 7248 was already published when some important problems were
   found in draft-ietf-stox-groupchat, which also applied to RFC 7248. 
   This problems were related to the diagrams describing the architecture
   of the system, hence the need for a -bis RFC.

Working Group Summary

   The STOX WG was created to tackle the task of producing the necessary
   specifications for SIP - XMPP interoperability. Presence was part of this
   work and the result was published as RFC 7248.

   Unfortunately, some issues raised by Ben Campbell [AD Note: Prior to 
   becoming AD] during the review of draft-ietf-stox-groupchat also 
   applied to draft-ietf-stox-presence, but it was already a published 
   RFC. The issues raised where specifically:

   The consensus was to create a new document rather than submitting
   errata since the changes are significant.

Document Quality

   During the review of this document, special attention was directed at the diagrams
   and signalling flows, which were throroughly reviewed by Markus Isomaki and
   Ben Campbell. Some vestiges of RFC 7248 were still present in the text, which the
   author corrected as per the received feedback. Diagrams were also further adjusted
   to better express the single gateway model (RFC 7248 used a dual-gateway
   architecture, as mentioned above). Last, terminology was clarified in order
   to better express the responsibilities of the involved signalling entities on the
   SIP side: 'SIP Proxy' replaced 'SIP server' and the role of a possibly separate
   SIP presence server was also clarified.

   All issues raised have been addressed and the document shepherd is
   not aware of any further standing problems with the document moving
   forward.
