draft-johnston-sipping-cc-conferencing-01.txt Summary Session Initiation Protocol Call Control - Conferencing for User Agents
Author(s) Alan Johnston, Orit Levin

Abstract This document 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 different user agent (UA) types perspective: conference-unaware, conference-aware and focus UAs. The use of URIs in conferencing, OPTIONS for capabilities discovery, and call control using REFER are covered in detail with example call flow diagrams.

draft-ietf-sipping-dialog-package-01.txt Summary "An INVITE Inititiated Dialog Event Package for the Session Initiation Protocol (SIP", Jonathan Rosenberg, Henning Schulzrinne, 05-MAR-03,
This document defines a dialog event package for the SIP Events architecture, along with a data format used in notifications for this package. The dialog package allows users to subscribe to another user, an receive notifications about the changes in state of INVITE initiated dialogs that the user is involved in.

draft-rosenberg-sipping-conferencing-framework-01.txt Summary A Framework for Conferencing with the Session Initiation Protocol
Author(s) Jonathan Rosenberg
Organization ietf
State unknown
Date 2003-02-12
Size 101848 bytes
Abstract The Session Initiation Protocol (SIP) supports the initiation, modification, and termination of media sessions between user agents. These sessions are managed by SIP dialogs, which represent a SIP relationship between a pair of user agents. Because dialogs are between pairs of user agents, SIP's usage for two-party communications (such as a phone call), is obvious. Communications sessions with multiple participants, generally known as conferencing, are more complicated. This document defines a framework for how such conferencing can occur. This framework describes the overall architecture, terminology, and protocol components needed for multi- party conferencing. Table of Contents

draft-levin-sipping-conferencing-requirements-03.txt Summary "High Level Requirements for Tightly Coupled SIP Conferencing", Orit Levin, Roni Even, 06-MAR-03,
This document examines a wide range of conferencing requirements for tightly coupled SIP conferences. Separate documents will map the requirements to existing protocol primitives, define new protocol extensions, and introduce new protocols as needed. Together, these documents will provide a guide for building interoperable SIP conferencing applications.

draft-ietf-sip-join-01.txt Summary "The Session Inititation Protocol (SIP) 'Join' Header", Rohan Mahy, Dan Petrie, 06-MAR-03,
This document defines a new header for use with SIP multi-party applications and call control. The Join header is used to logically join an existing SIP dialog with a new SIP dialog. This primitive can be used to enable a variety of features, for example: 'Barge-In', answering-machine-style 'Message Screening' and 'Call Center Monitoring'. Note that definition of these example features is non- normative.

draft-wu-sipping-floor-control-04.txt Summary Protocol (SOAP) for Conference Floor Control Protocol (SOAP) for Conference Floor Control", Xiaotao Wu, 06-MAR-03,
During a conference, floor control coordinates simultaneous access to shared resource in multimedia conferences. Floor control allows applications and users to gain safe and mutually exclusive or non- exclusive access to the shared resources. This document defines an approach of using Session Initiation Protocol (SIP) event notification mechanism and Simple Object Access Protocol (SOAP) to perform floor control.
