The IESG has approved the following document: - 'Instant Messaging and Presence Purpose for the Call-Info Header Field in the Session Initiation Protocol (SIP)' (draft-saintandre-impp-call-info-04.txt) as Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Gonzalo Camarillo. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-saintandre-impp-call-info/ Technical Summary This document defines and registers a value of "impp" ("instant messaging and presence protocol") for the "purpose" header field parameter of the Call-Info header field in the Session Initiation Protocol (SIP). Working Group Summary This draft was discussed in the DISPATCH working group. The conclusion of those discussions was that it was appropriate to AD sponsor it given that it was not controversial. The document is simply about the registration of an additional call-info header token and as such could even be viewed as a formality. Document Quality 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? The document shepherd isn't aware of current implementations. However there was interest in this work by vendors already implementing I-D.ivov-xmpp-cusax draft and there is a general interest in improving the interoperability among real-time communication endpoints that support combined use of SIP and XMPP, which is the purpose of the newly proposed header parameter value. Personnel The document shepherd is Yana Stamcheva. The responsible area director is Gonzalo Camarillo.
