We have updated the draft. There are major additions to the normative
behavior, and all the call flows have been reworked with message details.
The document now has a fairly complete picture of the mechanism so I'd
encourage everyone to read it and comment on it. Otherwise, we just
need to close a few open issues and we are close to completion.
As always, comments most welcome. And, again, thanks to everyone on the
design team for their input and ideas.
Thanks,
Alan

This draft is a work item of the Basic Level of Interoperability for SIP
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-01.txt
Pages : 72
Date : 2008-11-02
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 (SA) 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.
