Overview

This document describes the registration of the MIME sub-type multipart/voice-message for use with the Voice Profile for Internet Mail (VPIM). A full description of usage can be found in the VPIM v2 specification.

1. Abstract

This document describes the registration of the MIME sub-type multipart/voice-message for use with the Voice Profile for Internet Mail (VPIM). A full description of usage can be found in the VPIM v2 specification [VPIM2]. This document revises an earlier sub-type registration in RFC 1911 [VPIM1].

2. VPIM Scope

The VPIM specification defines a restricted profile of the Internet multimedia messaging protocols for use between voice processing platforms. These platforms have historically been special-purpose computers and often do not have the same facilities normally associated with a traditional Internet Email-capable computer. As a result, VPIM also specifies additional functionality as it is needed. The profile is intended to specify the minimum common set of features to allow interworking between compliant systems.

3. Voice Message Interchange

3.1 multipart/voice-message

The MIME sub-type multipart/voice-message is defined to hold specific media contents that are interchanged in messages between voice messaging systems described in [VPIM2]. Essentially, the sub-type provides a simple wrapper that easily identifies the entire content as being the components of a single voice message. The sub-type is identical in semantics and syntax to multipart/mixed, as defined in [MIME2]. As such, it may be safely interpreted as a multipart/mixed by systems that do not understand the sub-type (only the identification as a voice message would be lost).

This mechanism allows the insertion of an explanatory preamble (e.g. VPIM voice message attached) for recipients who read the message with pre-MIME software, since the preamble will be ignored by MIME- compliant software.

In addition to the MIME required boundary parameter, a version parameter is also required for this sub-type. This is to distinguish, this refin...
