The IESG has approved the following document: - 'Interworking between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP): Presence' (draft-ietf-stox-7248bis-14.txt) as Proposed Standard This document is the product of the SIP-TO-XMPP Working Group. The IESG contact persons are Alexey Melnikov, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-stox-7248bis/ 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. Personnel The document shepherd is Saúl Ibarra Corretgé. The responsible Area Director is Ben Campbell.
