The IESG has approved the following document: - 'A Mechanism for Transporting User to User Call Control Information in SIP' (draft-ietf-cuss-sip-uui-17.txt) as Proposed Standard This document is the product of the Call Control UUI Service for SIP Working Group. The IESG contact persons are Alissa Cooper and Richard Barnes. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-cuss-sip-uui/ Technical Summary: This document defines a new SIP header field, User-to-User Information (UUI), to transport data between two SIP user agents opaquely. Also defined is an extension mechanism for new UUI packages. Working Group Summary: Was there anything in WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? There was nothing contentious during the WG process worth noting. Certain aspects like getting the right semantics for the hex encoding of the UUI data, whether or not conversion between encodings will be allowed at gateways, etc., engendered email discussions but consensus was reached by all concerned parties equitably. 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? There are reported implementations of earlier version of the draft from Avaya, Dialogic and Audiocodes. This is work that other SDOs (3GPP) are waiting for. Laura Liess and Shida Schubert deserve mention for WGLC related to this draft. Personnel: Who is the Document Shepherd? Who is the Responsible Area Director? Document Shepherd: Vijay K.
