This specification defines conferencing call control features for the
Session Initiation Protocol (SIP). This document builds on the
Conferencing Requirements and Framework documents to define how a
tightly coupled SIP conference works. The approach is explored from
the perspective of different user agent (UA) types:
conference-unaware, conference-aware, and focus UAs. The use of
Uniform Resource Identifiers (URIs) in conferencing, OPTIONS for
capabilities discovery, and call control using REFER are covered in
detail with example call flow diagrams. The usage of the isfocus
feature tag is defined. This document specifies an Internet Best Current
Practices for the Internet Community, and requests discussion and
suggestions for improvements.
