Voice Messaging Directory Service

Overview

RFC 4237, “Voice Messaging Directory Service”, is a Proposed Standard document published in October 2005 by G. Vaudreuil. The canonical text is published by the RFC Editor.

Abstract

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]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
