This document normatively updates RFC 3261, the Session Initiation
Protocol (SIP), to address an error in the specified handling of
success (2xx class) responses to INVITE requests. Elements following
RFC 3261 exactly will misidentify retransmissions of the request as a
new, unassociated request. The correction involves modifying the
INVITE transaction state machines. The correction also changes the
way responses that cannot be matched to an existing transaction are
handled to address a security risk. [STANDARDS TRACK]
