All,

This draft reflects the consensus from Dublin on moving forward with the PUBLISH mechanism for appearance seizure/selection.

In the design team, we have also made a change to the title of the draft an feature "Shared Appearances of a SIP AOR" or just "Shared Appearances" or SA. Feedback on this is most welcome.

We are continuing to refine the mechanism and hope to have a nearly final list of open issues to resolve for Minneapolis.

Thanks,
Alan

        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-00.txt
        Pages           : 57

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 the 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.
