Abstract

   This document describes the high-level requirements for Internet
   Voice Mail (IVM) and establishes a baseline of desired functionality
   against which proposed MIME profiles for Internet Voice Messaging can
   be judged.  IVM is an extension of the Voice Profile for Internet
   Mail (VPIM) version 2 designed to support interoperability with
   desktop clients.  Other goals for this version of VPIM include
   expanded interoperability with unified messaging systems, conformance
   to Internet standards, and backward compatibility with voice
   messaging systems currently running in a VPIM enabled environment.
   This document does not include goals that were met fully by VPIM
   version 2.

1.  Introduction

   Until recently, voice mail and call answering services were
   implemented as stand-alone proprietary systems.  Today, standards
   such as the Voice Profile for Internet Mail (VPIM) enable
   interoperability between such systems over the Internet.  VPIM
   version 1 [VPIM1] was experimental and was a first attempt at a Voice
   Profile for Internet Mail, but is now classified as Historical.  VPIM
   Version 2 [VPIM2] is an improvement on VPIM version 1 that was
   originally intended to provide interoperability between voice
   messaging systems only.  It describes a messaging profile that
   standardizes the exchange of voice mail over an IP messaging network
   using SMTP [DRUMSMTP] and MIME [MIME1].

   Because the number of desktop boxes is growing rapidly and will soon
   approach the number of desktop telephones, it is essential to
   consider the requirements of desktop email client applications
