The IESG has approved the following document: - 'Registration for Multiple Phone Numbers in the Session Initiation Protocol (SIP)' (draft-ietf-martini-gin-13.txt) as a Proposed Standard This document is the product of the Multiple AoR reachabiliTy InformatioN Indication Working Group. The IESG contact persons are Gonzalo Camarillo and Robert Sparks. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-martini-gin/ Technical Summary This document defines a mechanism by which a SIP server acting as a traditional Private Branch Exchange (SIP-PBX) can register with a SIP Service Provider (SSP) to receive phone calls for UAs designated by phone numbers. The mechanism requires that the multiple AoRs being registered are each globally unique, which is the case for fully qualified AoRs representing E.164 numbers. Working Group Summary Since this document relates to the registration of multiple AoRs in a single exchange, much of the discussion centered around the implications and limitations of the scheme. In particular, there was extensive discussion on potential requirements for globally reachable contact URIs, as well as the circumstances under which the multiple AoRs being registered would each be globally unique. Although the globally unique AoR requirement can be met for email-style URIs as well as URIs representing E.164 numbers, this document chooses to focus on URIs representing E.164 numbers only. Document Quality The document has been reviewed by participants within the IETF MARTINI WG, including SIP service providers as well as representatives from the PBX vendor community. It has gone through MARTINI WG last call. Personnel Bernard Aboba is the document shepherd for this document. Gonzalo Camarillo is the responsible AD.
