(IETF Last Call) (Greg Vaudreuil)
draft-ietf-vpim-vpimv2r2-04.txt Oct 25, 2001
draft-ietf-vpim-vpimv2r2-32k-02.txt Oct 25, 2001
draft-ietf-vpim-vpimv2r2-dur-02.txt Oct 25, 2001
MDN drafts (Tony Hansen/Greg Vaudreuil )
draft-vaudreuil-mdnbis-01.txt Nov 4, 2001
DSN drafts (Greg Vaudreuil)
draft-moore-1891bis-00.txt June 21, 2001
draft-vaudreuil-1892bis-00.txt June 15, 2001
draft-vaudreuil-1893bis-00.txt June 15, 2001
draft-vaudreuil-1893ext-01.txt Nov 6, 2001
Quick summary by chair - we are in IETF last call which will end on New
Year's Eve. Following an IESG review, they will be going to RFC editor.
Report by Greg Vaudreuil: MDN, DSN drafts are completed. Both are on 2
weeks last call (not sure about close date).
The MDN extension document includes an additional set of status codes.
Status: ready to move.
VPIM Addressing (IETF last call) - 5 minutes (Glenn Parsons)
draft-ietf-vpim-address-02.txt Oct 26, 2001
IETF last call. (also ending on New Year's Eve)
VPIM Directory - 5 minutes (Greg Vaudreuil)
Voice Messaging Directory Service (schema)
draft-ietf-vpim-vpimdir-01.txt Nov 16, 2001
Voice Message Routing Service
draft-ietf-vpim-routing-01.txt Sep 10, 2000 (expired)
VPIM routing:
No open issues. It is based on RFC 2916, and will be revised when ENUM is
revised. Ready for WG last call - may wait for VPIM LDAP schema
VPIM Schema:
Several changes made - No more ASN.1, schema now auxiliary to INET person
Many comments received after ID deadline - will be incorporated, BNF fixes
received (Thanks !!)
One major open issue: should we support an additional query mode for direct
retrieval of spoken name and mailbox status directly from VM? (two-stage
query).
Pro: Easier to deploy in existing directories, smaller centralized DB
Con: Excessive latency may require LDAP V3 referrals, more option, more
complex.
Two stage query options:
1. Application-layer referral - define an additional attribute with URL of
auxiliary directory server.
2. Split schema into two objects. Use LDAP V3 referral if second object on
auxiliary server - add unnecessary latency for centralized case
3. Retain schema. Use chaining
- preserve schema complicates directory server.
- Serious concerns about latency
Ned Freed: doubts about operational difficulties (based on prior
experience). Also - questioned the standardization of the schema and the
options of enforcing it.
Also LDAP version from U. of Michigan does not support authentication
flexibility.
Proposal - adopting option 3. Work Group approves
IVM - 60 minutes
Goals for Internet Voice Mail
(AD review) (Emily Candell)
draft-ietf-vpim-ivm-goals-03.txt June 15, 2001
Approved !!
Critical Content of Internet Mail
(AD review) (Eric Burger)
draft-ietf-vpim-cc-04.txt March 30, 2001 (expired)
Message Context for Internet Mail
(AD review) (Eric Burger)
draft-ietf-vpim-hint-07.txt June 5, 2001 (expired)
Last call asked for by Ned Freed (new year eve). Advise from AD: keep an
eye. If it disappears - repost. (Since it went to last call - expiry date
does not apply anymore).
audio/wav with MS-GSM vs. audio/basic with mu-law
(Charles Eliot)
draft-ema-vpim-msgsm-00.txt April 1, 1999 (deleted)
draft-ema-vpim-wav-00.txt June 20, 1999 (deleted)
Codec consensus:
Mandatory to receive and play
MS-GSM as WAV
Audio/wav
G.711 as raw
Charles Elliot from Microsoft indicated some legal issues to do with IPR
owned by Microsoft. The documents were rewritten and are awaiting legal
response whether they are royalty free. Not resolved as of now.
WG agreed on Feb. 1st as a deadline for Microsoft response. Otherwise -
will go with G.711 only.
The rule (Ned Freed) - a pointer in the document referring to the licensing
terms.
Internet Voice Messaging (Stuart McRae)
draft-ietf-vpim-ivm-03.txt Nov 29, 2001
IVM Update (by Stuart McRae, read by Glenn Parsons)
Attempted to reduce the number of SHOULDs and make them qualified MUSTs or
MAYs
Clients that support IVM MUST generate message context of voice-message, but
MUST-NOT require it on received message
Updates about Critical Content, as well as message content.
Must use audio/wav or audio/basic unless sender is aware recipient can
handle other types. May include spoken name. When forwarding MUST preserve
content type of audio body parts.
Added considerations for several Interoperability points
Updates for Gateway Requirements:
Possible list of Gateway Issues sent to the list.
Should this be included in IVM? Has it been reviewed?
Is it complete/accurate?
Are there any other recommendations to make?
Should it be updated for inclusion as an addendum? Discussion concluded it
should not be included in IVM but possibly included in an Implementer's
Guide.
Minor updates on other sections (Security considerations and added
references to the security sections)
VPIM Addenda - 20 minutes
Binary & channel IMAP extensions for VPIM Messages
(Lyndon Nerenberg)
draft-nerenberg-imap-channel-01.txt Nov 27, 2001
draft-nerenberg-imap-binary-05.txt Sept 20, 2001
Discussion held on IMAP Voice Mail list. Author was not attending. Chairman
encourages attendees to review the channel document.
Calling Line Identification for VPIM Messages
(Glenn Parsons)
draft-ema-vpim-clid-02.txt June 2001
Some clarifications needed as to the number format (E.164, NANP, private
numbering scheme)
WG last call to informational ended August 31, 2001.
Outstanding action on Greg to provide structured syntax by February 1st.
Voice Messaging IMAP Client Behaviour (Glenn Parsons)
draft-ema-vpim-cb-02.txt July 18, 2001
AD (Ned Freed) hasn't yet got around to reviewing it...
SIP MWI (Rohan Mahy)
draft-mahy-sip-message-waiting-02.txt July 2001
Author was not attending. Status unchanged (this doc is waiting for SIP
events in SIP WG to go through)
SNAP (Noam Shapira)
draft-shapira-snap-02.txt Nov 21, 2001
Presentation on latest changes to SNAP draft:
-Structural changes in the draft
-Bind HTTP to SNAP
-Payload format is 2822 like
-Added Security and IANA considerations
-MessageType changed to Message-Context (compatible to HINT)
-MsgImportance and MsgSensitivity reference to MIXER (RFC 2156)
Greg/Ned - the reference to MIXER should be removed and another reference
should be used.
Why in VPIM WG?
Notification - a major Unified Messaging feature / component. VPIM is the
natural place for UM discussions
Status of draft: small fixes are needed.
Glenn - SNAP work can be finished before VPIM rechartering.
Ned Freed asked that it is added to VPIM new charter.
Also - Ned said that if there will be a proven justification for HTTP (using
draft-moore-using-http-01.txt) he will not object to HTTP.
Draft is ready for last call.
Greg - suggests to move SNAP as email notification protocol.
Pete Resnick - Suggests to move to last call and not to rehash it in IMAP
WG. Submit to Ned for IETF review.
Ned - review if the use of HTTP is according to guidelines
VPIM Re-Charter discussion - 20 minutes
Charter is about to be reached (expected - next meeting).
What is next?
Ideas:
* TUI Profile for Internet Mail
-Need profile for TUI access to messages
and submission of messages to message store
-VPIM V2 addresses server to server.
IVM addresses server to GUI client and GUI to GUI
* TUI Profile for Message Access
-Profile IMAP for TUI message access
-Message context in IMAP list search
-Channel+RTSP for streaming access to context
-Server side transcoding request
-Profile SMTP-Submit for telephone answering
-Quota override, authentication
-ISUP/ISDN parameters, callback number, non-mail user
-Caller ID block handling
-Message forward without download of forwarded content
-Server side transcoding request
* Notification
* Extend SORT to support Message-Context
* Add support of per Message-Context counters in
STATUS command
* Add support for STATUS of multiple folders
* Add support for IDLE of multiple folders
* Standardize English names for standard
(system) folders
* Add support of two new IMAP flags (/SPAM, /ADULT)
* Client submission
* Client retrieval
Initial response - objection to some of the IMAP related stuff.
Most probable way - close the VPIM group and open as a new WG based on the
agreed upon charter.
Will revisit options on the list and at the next meeting.
Wrap Up - 5 minutes
Meeting adjourned at 11:32 AM
