The IESG has received a request from an individual submitter to consider the following document: - 'Using the International Mobile station Equipment Identity (IMEI) Uniform Resource Name (URN) as an Instance ID' <draft-allen-dispatch-imei-urn-as-instanceid-12.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-12-23. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Note that this draft was already IETF Last Called in July. The current revision of the draft is supposed to have addressed all the comments received during the previous IETF Last Call. 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 in RFC 5626 [1] that state "If a URN scheme other than UUID (Universally unique identifier) is used, the UA (User Agent) MUST only use URNs for which an RFC (from the IETF stream) defines how the specific URN needs to be constructed and used in the "+sip.instance" Contact header field parameter for outbound behavior."
