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]

This document is a product of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
