This draft is a work item of the Basic Level of Interoperability for SIP S= ervices Working Group of the IETF. Title : Shared Appearances of a Session Initiation Protocol (SIP= ) Address of Record (AOR) Author(s) : Alan Johnston Mohsen Soroushnejad Venkatesh Venkataramanan Filename : draft-ietf-bliss-shared-appearances-15.txt Pages : 71 Date : 2013-01-16 Abstract: 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 feature allows several user agents (UAs) to share a common AOR, learn about calls placed and received by other UAs in the group, and pick up or join calls within the group. This document discusses use cases, lists requirements and defines extensions to implement this feature. This specification updates RFC3261 and RFC4235.

A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-bliss-shared-appearances/ Technical Summary This Document describes the requirements and implementations of a group telephony feature which allows several user agents (UAs) to share a common AoR, learn about calls placed and received by other UAs in the group, and pick up join calls within the group. Working Group Summary There were no points where consensus were rough but extending pre-existing dialog event package rather than defining a new event package was seen as a controversial issue for some. Also to indicate whether a UA supports this specification, use of option tag was suggested over the use of implicit mechanism but WG decided to leave it as is as the server (appearance agent) can gracefully handle the existance of non-compliant UA. Document Quality There are existing implementations as far as I know. Some vendors have indicated their plan to implement the specification. Review by Robert Sparks (responsible AD) and Dale Worley have fine tuned the document by clarifying some unclarified text along with some contoversial issues mentioned above. Personnel Shida Schubert is the document shepherd and Robert Sparks is the responsible Area Director.
