The IESG has approved the following document: - 'Internet Assigned Numbers Authority (IANA) Registration of Instant Messaging and Presence DNS SRV RRs for the Session Initiation Protocol (SIP) ' <draft-loreto-simple-im-srv-label-03.txt> as a Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Jon Peterson. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-loreto-simple-im-srv-label-03.txt Technical Summary This document registers with IANA two new DNS SRV Protocol Labels for resolving Instant Messaging and Presence services with SIP. These registrations are necessary because the original definitions of the SRV system for resolving the protocol associated with the "im" and "pres" URI schemes did not register any SIP service. Working Group Summary This document is an individual submission. Document Quality The RAI-ART team reviewed this document (review by Miguel Garcia). Personnel Jon Peterson reviewed this document for the IESG, and is the document shepherd. Gen-ART review was provided by Suresh Krishnan. RFC-Editor Note Section 3, addition after the third paragraph on page 4 (before the paragraph "Section 5 of [RFC3856] states that...): ADDITION: SIP supports both page [RFC3428] and session [RFC4975] IM mode. However a DNS SRV lookup does not specify which SIP IM mode a domain offer. If the UAC supports both session mode and page mode, it is then suggest to try session mode first and if that mode is rejected, the UAC has to be ready to fall back to page mode. Section 7, "Normative References", addition as last reference: ADDITION: [RFC4975] Campbell, B., Mahy, R., and C. Jennings, "The Message Session Relay Protocol (MSRP)", RFC 4975, September 2007. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
