    Using the International Mobile station Equipment Identity (IMEI)
             Uniform Resource Name (URN) as an Instance ID
             draft-allen-dispatch-imei-urn-as-instanceid-13

Abstract

   This specification specifies how the Uniform Resource Name (URN)
   reserved for the GSMA (GSM Association) identities and its sub-
   namespace for the IMEI (International Mobile station Equipment
   Identity) can be used as an instance-id.  Its purpose is to fulfil
   the requirements for defining how a specific URN needs to be
   constructed and used in the "+sip.instance" Contact header field
   parameter for outbound behavior.

Internet-Draft      Using IMEI URN as an Instance ID       February 2014

1.  Introduction

   This specification specifies how the Uniform Resource Name reserved
   for GSMA identities and its sub-namespace for the IMEI (International
   Mobile station Equipment Identity) as specified in
   draft-montemurro-gsma-imei-urn-20 [1] can be used as an instance-id
   as specified in RFC 5626 [2] and also as used by RFC 5627 [3].

   RFC 5626 [2] specifies the "+sip.instance" Contact header field
   parameter that contains a URN as specified in RFC 2141 [4].  The
   instance-id uniquely identifies a specific UA instance.  This
   instance-id is used as specified in RFC 5626 [2] so that the SIP
   (Session Initiation Protocol) registrar (as specified in RFC 3261
   [5]) can recognize that the contacts from multiple registrations
   correspond to the same UA.  The instance-id is also used as specified
   by RFC 5627 [3] to create Globally Routable User Agent URIs (GRUUs)
   that can be used to uniquely address a UA when multiple UAs are
   registered with the same Address of Record (AoR).

   RFC 5626 [2] requires that a UA SHOULD create a Universally Unique
