All,
Some of the major changes to this version of the document include:
- Publish only on appearance selection or seizure/call join or
bridge/call take or pickup
- Allow Appearance Agent to subscribe to dialog events if it is not a
call stateful proxy or B2BUA(shown in Section 10.13)
- Publications to the shared appearances AOR
- Major rewrite of call flows
As always, comments most welcome.
Thanks,
Alan

Services Working Group of the IETF.
Title : Shared Appearances of a Session Initiation Protocol
(SIP) Address of Record (AOR)
Author(s) : A. Johnston, et al.
Filename : draft-ietf-bliss-shared-appearances-02.txt
Pages : 65
Date : 2009-03-09
This document describes the requirements and implementation of a
group telephony feature commonly known as Bridged Line Appearance
(BLA) or Multiple Line Appearance (MLA), or Shared Call/Line
Appearance (SCA). When implemented using the Session Initiation
Protocol (SIP), it is referred to as shared appearances of an Address
of Record (AOR) since SIP does not have the concept of lines. This
feature is commonly offered in IP Centrex services and IP-PBX
offerings and is likely to be implemented on SIP IP telephones and
SIP feature servers used in a business environment. This document
lists requirements and compares implementation options for this
feature. Extensions to the SIP dialog event package are proposed.
