Ballot Text
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.

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.
