This document defines a bidirectional protocol mapping for the exchange of instant
messages in the context of a one-to-one chat session between a user of the Session
Initiation Protocol (SIP) and a user of the Extensible Messaging and Presence Protocol

were there decisions where the consensus was particularly
This document has been initially reviewed in the DISPATCH WG as per the RAI area
process for new work. The STOX WG has been chartered as a result of the submission of
this and other documents that aim to define specifications for interworking between the
Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol
(XMPP) based systems. This document has been subjected to a number of reviews
initially in the DISPATCH WG and in the STOX WG after its creation. A number of
thorough reviews have also been made in the last few months and the document has
been updated to address all raised issues and concerns. There were no controversial
points regarding it.
Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to
implement the specification? Are there any reviewers that
merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type or other expert review,
what was its course (briefly)? In the case of a Media Type
review, on what date was the request posted?
There are already several vendors having full or partial implementations of the
specification, among which Jabber/Cisco, Kamailio (OpenSER), AG Projects (Silk Server).
Some of the people behind these implementations have actively participated in the
discussions in the WG.
