RFC3458 - Message Context for Internet Mail

This memo describes a new RFC 2822 message header, "Message-Context". This header provides information about the context and presentation characteristics of a message. A receiving user agent (UA) may use this information as a hint to optimally present the message. [STANDARDS-TRACK]

RFC3459 - Critical Content Multi-purpose Internet Mail Extensions (MIME) Parameter

This document describes the use of a mechanism for identifying body parts that a sender deems critical in a multi-part Internet mail message. The mechanism described is a parameter to Content-Disposition, as described by RFC 3204. By knowing what parts of a message the sender deems critical, a content gateway can intelligently handle multi-part messages when providing gateway services to systems of lesser capability. Critical content can help a content gateway to decide what parts to forward. It can indicate how hard a gateway should try to deliver a body part. It can help the gateway to pick body parts that are safe to silently delete when a system of lesser capability receives a message. In addition, critical content can help the gateway chose the notification strategy for the receiving system. Likewise, if the sender expects the destination to do some processing on a body part, critical content allows the sender to mark body parts that the receiver must process. [STANDARDS-TRACK]

RFC3773 - High-Level Requirements for Internet Voice Mail

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. This memo provides information for the Internet community.

RFC3801 - Voice Profile for Internet Mail - version 2 (VPIMv2)

This document specifies a restricted profile of the Internet multimedia messaging protocols for use between voice processing server platforms. The profile is referred to as the Voice Profile for Internet Mail (VPIM) in this document. 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. This profile is intended to specify the minimum common set of features to allow interworking between conforming systems. This document obsoletes RFC 2421 and describes version 2 of the profile with greater precision. No protocol changes were made in this revision. A list of changes from RFC 2421 are noted in Appendix F. Appendix A summarizes the protocol profiles of this version of VPIM. [STANDARDS-TRACK]

RFC3802 - Toll Quality Voice - 32 kbit/s Adaptive Differential Pulse Code Modulation (ADPCM) MIME Sub-type Registration

This document describes the registration of the MIME sub-type audio/32KADPCM Adaptive Differential Pulse Code Modulation for toll quality audio. This audio encoding is defined by the ITU-T in Recommendation G.726. [STANDARDS-TRACK]

RFC3803 - Content Duration MIME Header Definition

This document describes the MIME header Content-Duration that is intended for use with any time varying media content (typically audio/* or video/*). [STANDARDS-TRACK]

RFC3804 - Voice Profile for Internet Mail (VPIM) Addressing

This document lists the various Voice Profile for Internet Mail (VPIM) email address formats that are currently in common use and defines several new address formats for special case usage. Requirements are imposed on the formats of addresses used in VPIM submission mode. [STANDARDS-TRACK]

RFC4237 - Voice Messaging Directory Service

This document provides details of the Voice Profile for Internet Mail (VPIM) directory service. The service provides the email address of the recipient that is given a telephone number. It optionally provides the spoken name of the recipient and the media capabilities of the recipient.

The VPIM directory Schema provides essential additional attributes to recreate the voice mail user experience using standardized directories. This user experience provides, at the time of addressing, basic assurances that the message will be delivered as intended. This document combines two earlier documents, one from Anne Brown and one from Greg Vaudreuil, that define a voice messaging schema into a single working group submission. [STANDARDS-TRACK]

RFC4238 - Voice Message Routing Service

Voice messaging is traditionally addressed using telephone number addressing. This document describes two techniques for routing voice messages based on a telephone number. The complete service uses the Voice Profile for Internet Mail (VPIM) Directory service to lookup a VPIM email address with a telephone number and confirm that the address is both valid and associated with the intended recipient. However, this service will take time to become widely deployed in the near term. This document also describes a basic send-and-pray service that routes and delivers messages using only the ENUM telephone number resolution service and the existing DNS mail routing facilities.

RFC4239 - Internet Voice Messaging (IVM)

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. [STANDARDS-TRACK]
