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.
