Instant Message Disposition Notification

Overview

RFC 5438, “Instant Message Disposition Notification”, is a Proposed Standard document published in February 2009 by E. Burger, H. Khartabil. The canonical text is published by the RFC Editor.

Abstract

Instant Messaging (IM) refers to the transfer of messages between users in real-time. This document provides a mechanism whereby endpoints can request Instant Message Disposition Notifications (IMDN), including delivery, processing, and display notifications, for page-mode instant messages.

The Common Presence and Instant Messaging (CPIM) data format specified in RFC 3862 is extended with new header fields that enable endpoints to request IMDNs. A new message format is also defined to convey IMDNs.

This document also describes how SIP entities behave using this extension. [STANDARDS-TRACK]
