	Title           : An Interactive Voice Response (IVR) Control Package for the Media Control Channel Framework
	Author(s)       : S. McGlashan, et al.
	Filename        : draft-ietf-mediactrl-ivr-control-package-10.txt
	Pages           : 160
	Date            : 2011-01-04

This document defines a Media Control Channel Framework Package for
Interactive Voice Response (IVR) dialog interaction on media
connections and conferences.  The package defines dialog management
request elements for preparing, starting and terminating dialog
interactions, as well as associated responses and notifications.
Dialog interactions are specified in a dialog language.  This package
defines a lightweight IVR dialog language (supporting prompt
playback, runtime controls, Dual-Tone Multi-Frequency (DTMF)
collection and media recording) and allows other dialog languages to
be used.  The package also defines elements for auditing package
capabilities and IVR dialogs.

RFC5552, "SIP Interface to VoiceXML Media Services"
Source of RFC: mediactrl (rai)

Errata ID: 1994

Status: Reported
Type: Technical

Reported By: Henry Lum
Date Reported: 2010-01-04

Section 2.4 says:

session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in reverse order, into an element
      of the session.connection.redirect array.

It should say:

session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in order appeared in the
      History-Info header, into an element of the
      session.connection.redirect array.

Notes:

The elements in the History info header is designed as a tree-like
structure from the origination to the destination where each
forwarding proxy appends to the end of the header and add an
index. The original RFC text requires that the elements to be shown in
VXML session.connection.redirect array in reverse order and this is
incorrect based on the definition of session.connection.redirect. The
first element in the array should be the original called number which
maps to index=3D1 in history-info, and the last element should be the
last redirected number which is the last element in history-info.
----------------------------------------------------------------------
Recommended status:  (correct) Verified

The definition of session.connection.redirect from the VXML 2.0
specification (http://www.w3.org/TR/2004/REC-voicexml20-20040316/) is:

    session.connection.redirect
	This variable is an array representing the connection redirection
	paths. The first element is the original called number, the last
	element is the last redirected number. Each element of the array
	contains a uri, pi (presentation information), si (screening
	information), and reason property. The reason property can be
	either "unknown", "user busy", "no reply", "deflection during
	alerting", "deflection immediate response", "mobile subscriber not
	reachable".

As such, copying the History-Info values into
session.connection.redirect in the same order is somewhat more
correct, as the first History-Info value should be the original
request-URI.  But History-Info may contain other values other than the
ones that are ancestral to the INVITE containing it, and assembling
the correct redirection sequence may require some additional
processing.  Also, the definition of History-Info is being updated
(draft-ietf-sipcore-rfc4244bis) to provide better recording of
redirection sequences.  Documenting how to extract the redirection
sequence in a way that would work in all cases is a significant piece
of work.

Currently, the best straightforward specification is to map the
elements in forward order:

session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Entries (hi-entry) in the
      History-Info header are mapped, in order they appear in the
      History-Info header, into elements of the
      session.connection.redirect array.

It appears that definitions of the component values of the array
elements need amending as well:

      *  uri - Set to the hi-targeted-to-uri value of the History-Info
         entry

Strictly speaking, the hi-targeted-to-uri contains "header
parameters", including "Reason" and "Privacy", which are not derived
from the request-URI of the corresponding INVITE, and are not
meaningful considered as part of that URI.  So this definition should
be "Set to the hi-targeted-to-uri value, without 'headers', of the
History-Info entry"

      *  si - Set to the value of the "si" parameter if it exists,
         undefined otherwise

I can find no reference to the "si" value in VXML 2.0, RFC 4244, or in
draft-ietf-sipcore-rfc4244bis-02 -- is this entry a mistake?
Ironically, taken verbatim, this definition requires the "si" value to
always be undefined, which is the same effect as if its definition
were deleted from the RFC.

RFC5552, "SIP Interface to VoiceXML Media Services"
Source of RFC: mediactrl (rai)

Errata ID: 1994

Status: Reported
Type: Technical

Reported By: Henry Lum
Date Reported: 2010-01-04

Section 2.4 says:

session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in reverse order, into an element
      of the session.connection.redirect array.

It should say:

session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in order appeared in the
      History-Info header, into an element of the
      session.connection.redirect array.

Notes:

The elements in the History info header is designed as a tree-like
structure from the origination to the destination where each
forwarding proxy appends to the end of the header and add an
index. The original RFC text requires that the elements to be shown in
VXML session.connection.redirect array in reverse order and this is
incorrect based on the definition of session.connection.redirect. The
first element in the array should be the original called number which
maps to index=3D1 in history-info, and the last element should be the
last redirected number which is the last element in history-info.
----------------------------------------------------------------------
Recommended status:  (correct) Verified

The definition of session.connection.redirect from the VXML 2.0
specification (http://www.w3.org/TR/2004/REC-voicexml20-20040316/) is:

    session.connection.redirect
	This variable is an array representing the connection redirection
	paths. The first element is the original called number, the last
	element is the last redirected number. Each element of the array
	contains a uri, pi (presentation information), si (screening
	information), and reason property. The reason property can be
	either "unknown", "user busy", "no reply", "deflection during
	alerting", "deflection immediate response", "mobile subscriber not
	reachable".

As such, copying the History-Info values into
session.connection.redirect in the same order is somewhat more
correct, as the first History-Info value should be the original
request-URI.  But History-Info may contain other values other than the
ones that are ancestral to the INVITE containing it, and assembling
the correct redirection sequence may require some additional
processing.  Also, the definition of History-Info is being updated
(draft-ietf-sipcore-rfc4244bis) to provide better recording of
redirection sequences.  Documenting how to extract the redirection
sequence in a way that would work in all cases is a significant piece
of work.

Currently, the best straightforward specification is to map the
elements in forward order:

session.connection.redirect:  This array is populated by information
     contained in the History-Info [RFC4244] header in the initial
     INVITE or is otherwise undefined.  Each entry (hi-entry) in the
     History-Info header is mapped, in order, into an element of the
     session.connection.redirect array.

Looking at an erratum to RFC 5552 ("SIP Interface to VoiceXML Media
Services"), I ran into the following oddities in the definition of the
following two componets of the elements of the
session.connection.redirect array:

      *  uri - Set to the hi-targeted-to-uri value of the History-Info
         entry

This is badly phrased:  Strictly speaking, the hi-targeted-to-uri
contains "header parameters", including "Reason" and "Privacy", which
are not derived from the request-URI of the corresponding INVITE, and
are not meaningful considered as part of that URI.  So this definition
should be "Set to the hi-targeted-to-uri value, without 'headers', of
the History-Info entry"

      *  si - Set to the value of the "si" parameter if it exists,
         undefined otherwise

I can find no reference to the "si" value in VXML 2.0, RFC 4244, or in
draft-ietf-sipcore-rfc4244bis-02 -- is this entry a mistake?
Ironically, taken verbatim, this definition requires the "si" value to
always be undefined, which is the same effect as if its definition
were deleted from the RFC.

What do people think of this?  Should these be fixed by an erratum?
What was really meant?

VXML2 does define a si (screening indicator) property in each element in
the session.connection.redirect. But you are correct that RFC4244 makes
no reference to screening indicator at all for Histroy-Info header so
our implementation ends up always setting it to undefined.

The IESG has approved the following document:
- 'An Interactive Voice Response (IVR) Control Package for the Media
   Control Channel Framework'
  (draft-ietf-mediactrl-ivr-control-package-11.txt) as a Proposed
Standard

This document is the product of the Media Server Control Working Group.

The IESG contact persons are Robert Sparks and Gonzalo Camarillo.

A URL of this Internet Draft is:
http://datatracker.ietf.org/doc/draft-ietf-mediactrl-ivr-control-package/




Technical Summary
  
  This document defines a Media Control Channel Framework Package for
  Interactive Voice Response (IVR) dialog interaction on media
  connections and conferences. The package defines dialog management
  request elements for preparing, starting and terminating dialog
  interactions, as well as associated responses and notifications.
  Dialog interactions are specified in a dialog language. This package
  defines a lightweight IVR dialog language (supporting prompt
  playback, runtime controls, DTMF collect and media recording) and
  allows other dialog languages to be used. The package also defines
  elements for auditing package capabilities and IVR dialogs.

Working Group Summary

  There was significant working group participation in the creation of
  this document and it represents a strong consensus.

Document Quality

  There are at least four independent implementations of the control
  package described by this document.

  This document has been stable for several versions, with small changes

  in each revision, discussed on the mailing list. Most of the recent 
  changes have been suggested based on implementer experience.

  Type review for the media types defined in this document was 
  requested June 18, 2009.

  The document has had RAI expert review (by Ben Campbell) and early
  SECDIR review (by Donald Eastlake).

Personnel

  Spencer Dawkins is the Document Shepherd.
  Robert Sparks is the responsible Area Director.

RFC Editor Note

In Section 4, 7th paragraph:

OLD:
   Some elements in this control package contain attributes whose value
   is descriptive text primarily for diagnostic use.  The implementation
   can indicated the language used in the descriptive text by means of a
   'desclang' attribute ([RFC2277]).
                      

NEW:
   Some elements in this control package contain attributes whose value
   is descriptive text primarily for diagnostic use.  The implementation
   can indicated the language used in the descriptive text by means of a
   'desclang' attribute ([RFC5646],[RFC2277]).

Assuming that the "screening indicator" is intended to prevent the
recipient from knowing the origin, the "si" properties should be
driven by the "Privacy" headers encoded into the History-Info.

Screening indicators, as defined in the ISDN, are nothing whatsoever to do =

Assuming that the "screening indicator" is intended to prevent the
recipient from knowing the origin, the "si" properties should be
driven by the "Privacy" headers encoded into the History-Info.

Hi Everyone,

I'm resending this mail of more than a year ago, as Robert Sparks was
kind enough to point out in a review that it seemed likely that the list
members had actually not received it!

Regards,

Mark.

I agree that the correction is valid, although I would make a slight
grammatical change to the correct text, as follows:

Corrected Text
--------------
session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in order, into an element of the=20
	session.connection.redirect array.

The following errata report has been submitted for RFC5552,
"SIP Interface to VoiceXML Media Services".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=3D5552&eid=3D1994

--------------------------------------
Type: Technical
Reported by: Henry Lum <henry.lum@genesyslab.com>

Section: 2.4

Original Text
-------------
session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in reverse order, into an element
      of the session.connection.redirect array.

Corrected Text
--------------
session.connection.redirect:  This array is populated by information
      contained in the History-Info [RFC4244] header in the initial
      INVITE or is otherwise undefined.  Each entry (hi-entry) in the
      History-Info header is mapped, in order appeared in the
History-Info header, into an element of the session.connection.redirect
array.

Notes
-----
The elements in the History info header is designed as a tree-like
structure from the origination to the destination where each forwarding
proxy appends to the end of the header and add an index. The original
RFC text requires that the elements to be shown in VXML
session.connection.redirect array in reverse order and this is incorrect
based on the definition of session.connection.redirect. The first
element in the array should be the original called number which maps to
index=3D1 in history-info, and the last element should be the last
redirected number which is the last element in history-info.

Instructions:
-------------
This errata is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
