Abstract

   This document describes the carriage of voicemail messages over
   Internet mail as part of a unified messaging infrastructure.

   The Internet Voice Messaging (IVM) concept described in this document
   is not a successor format to VPIM v2 (Voice Profile for Internet Mail
   Version 2), but rather an alternative specification for a different
   application.

1.  Introduction

   For some forms of communication, people prefer to communicate using
   their voices rather than typing.  By permitting voicemail to be
   implemented in an interoperable way on top of Internet Mail, voice
   messaging and electronic mail no longer need to remain in separate,
   isolated worlds, and users will be able to choose the most
   appropriate form of communication.  This will also enable new types
   of devices, without keyboards, to be used to participate in
   electronic messaging when mobile, in a hostile environment, or in
   spite of disabilities.

   There exist unified messaging systems that will transmit voicemail
   messages over the Internet using SMTP/MIME, but these systems suffer
   from a lack of interoperability because various aspects of such a
   message have not hitherto been standardized.  In addition, voicemail
   systems can now conform to the Voice Profile for Internet Messaging
