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
