VPIM v1 v2 Goals
  • Interworking between multi-vendor voice messaging
    systems
  • Support of voice and fax attachments
  • Interworking between voice messaging systems and
    Internet mail
  • Interworking between voice messaging systems and
    desktops

4
VPIM v2 Specification
RFC 2421
  • MIME extensions preserve a full voice messaging
    feature set (e.g., multipart/voice-message)
  • ESMTP extensions allow efficient and reliable
    transport (e.g., DSN, Binary, Size)
  • G.726 TIFF-F encoded voice fax
  • vCard encodes senders business card

EHLO vm.vm.ca CHUNKING, BINARYMIME, PIPELINING,
DSN SIZE250000 BDAT

5
VPIM v2 Content
  • MIME message format
  • multipart/voice-message is the container
  • only VM specific contents defined in VPIM are
    enveloped
  • G.726 audio in audio/32KADPCM
  • Optional spoken name subject in addition to
    message
  • TIFF-F facsimile in image/TIFF
  • Versit vCard to contain originator info
  • Spoken name
  • Text name, address, phone, etc.
  • Restrictions
  • no text allowed (intended
  • must send NDN if cannot render fax or other
    unknown content

6
VPIM v2 Transport
  • ESMTP
  • Size negotiation
  • Pipelining of commands
  • Binary data transfer
  • Chunking binary data
  • VPIM v2 Notifications
  • Delivery Status Notifications (DSN)
  • Mandatory
  • Defined machine parsable
  • Spoken error messages
  • Message Disposition Notifications (MDN)
  • Optional

7
Addressing
  • Accommodate limitations of addressing messages
    from a telephone.
  • Given a numeric target address entered from a
    telephone, generate a numeric canonical address,
    and resolve it to an Internet address
  • Optionally return other information
  • text name, spoken name, etc.
  • Telephone keypad is numeric, but VPIM uses
    Internet Mail addresses
  • 613 763 7582 ? 6137637582_at_NortelNetworks.com

  • EMA Interoperability Committee
  • Reviewed in 1994
  • EMA Voice Messaging Committee
  • Created in 1995

VPIM Conformance
  • Customer confidence that VPIM products are
    conformant and actually do interoperate
  • End systems should be content and transport
    conformant
  • Intermediate mail gateways should be transport
    conformant
  • Registration by vendor
  • Declaration of Conformity Interoperability
  • No test labs, no policing, no sticker
  • EMA is Registrar

VPIMv2 Deployment
  • Product
  • All major VM vendors have committed to support
    VPIM
  • Many vendors support VPIM in released products
  • Service
  • Many service providers and large enterprises are
    interested in VPIM
  • Several service providers have deployment plans
    for 1999
  • Trials
  • Demonstrations planned for summer fall 1999
  • Testing is ongoing

12
VPIM v2 Status
  • Approved by IETF as a Proposed Standard in
    September 1998
  • Next steps
  • Document interoperability
  • Fix specification
  • Clarify ambiguities in VPIM v2
  • Reissue
  • Propose progression to Draft Standard Q3 1999

13
VPIM v3 Goals
  • ltdraft-ema-vpimv3-goals-00.txtgt
  • Laile L. Di Silvestro
  • This document describes the goals of the Voice
    Profile for Internet Messaging (VPIM), Version 3
    and establishes a baseline of desired
    functionality against which proposed MIME
    profiles for Internet voice messaging can be
    judged.

14
VPIM Unified Message MIME Sub-type Registration
  • ltdraft-ema-vpim-um-01.txtgt
  • Greg Vaudreuil, Glenn Parsons, Marty Cohen
  • This document describes the registration of the
    MIME sub-types multipart/voice-message and
    multipart/fax-message for use with the Voice
    Profile for Internet Mail (VPIM) and other
    Internet Mail profiles for Unified Messaging

VPIM v2 - v3 Interworking
  • To be Written...

16
VPIM Addressing
  • ltdraft-ema-vpim-address.txtgt
  • Glenn Parsons
  • This document lists the various VPIM email
    addresses that are currently in common use and
    defines several new address formats for special
    case usage.

17
VPIM v2 Addresses
  • Mailbox
  • for use as a private numbering plan (any number
    of digits)
  • e.g. 5552722_at_lucent.com, 6137637582_at_nortelnetwo
    rks.com
  • Mailbox Numberextension
  • for use as a private numbering plan with
    extensions any number of digits, use of as
    separator
  • e.g. 5552722111_at_lucent.com
  • international number
  • for international telephone numbers conforming to
    E.164 - maximum of 15 digits
  • e.g. 16137637582_at_nortelnetworks.com
  • international numberextension
  • for international telephone numbers conforming to
    E.164 - maximum of 15 digits, with an extension
    (e.g. behind a PBX) that has a maximum of 15
    digits.
  • - e.g. 17035245550230_at_ema.org

18
VPIMv3 Addresses
  • Onramp/Offramp - RFC2303 based
  • VPIM
  • Onramp submission to a VPIM gateway
  • E.g., vpim6137637582_at_gateway.net
  • VOICE
  • Offramp to voice delivery via out call
  • E.g., voice2125551234_at_bellatlantic.net

  • Gateway address to AMIS systems
  • E.g., amis4013278144/sysnum4013279542_at_company.co
    m
  • FAX
  • Offramp to fax terminal (per Fax WG)

VPIM v3 Specification
  • ltdraft-ema-vpimv3-00.txtgt
  • Greg Vaudreuil, Glenn Parsons
  • This document describes a new version of the VPIM
    specification for the interchange of voice
    messages between a voice messaging system as
    defined in VPIM and a unified messaging system.
    In this sense, a unified messaging system is
    capable of sending and receiving each of several
    different message types.
