SIP and ENUM

• Old draft-ietf-sipping-e164-01 has been split into child drafts– Now there is draft-peterson-enum-sip-00, a smaller text which

only defines the enumservice itself– SIPPING document will continue, with guidelines for SIP users

• That document has some new considerations (rfc2916bis)• Approach of this draft considers only SIP addresses-of-record

– Not ‘contact addresses’ that represent devices• Defines only an ‘E2U+SIP’ enumservice

– This follows the syntax we agreed to in Yokohama – will that be reflected in rfc2916bis?

– No further granularity required for addresses-of-record• No known open issues (anyone else got any?)• WG item?
