This document describes providing Conferencing call control
capabilities in the Session Initiation Protocol (SIP). This document
builds on the Conferencing Requirements and Framework documents to
show how a tightly coupled SIP conference will work. The approach is
explored from a user agent (UA) perspective. Three types of UAs are
described: a conferencing unaware UA, one capable of being a full
member of a conference, and one also capable of hosting a conference.
The use of URIs in conferencing, OPTIONS for capability discovery,
and call control using REFER are covered in detail with example call
flow diagrams.

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
Internet-Draft.
