This draft is a work item of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group of the IETF.
Title : Instant Message Sessions in SIMPLE
Author(s) : B. Campbell et al.
Filename : draft-ietf-simple-message-sessions-00.txt
Pages : 47

The SIP MESSAGE method is used to send instant messages, where each
message is independent of any other message. This is often called
pager-mode messaging, due to the fact that this model is similar to

session-mode. In session-mode, the instant messages are part of a
media session that provides ordering, a security context, and other
functions. This media session is established using a SIP INVITE, just
as an audio or video session would be established.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
