> This document normatively updates RFC 3261, the Session Initiation
> Protocol (SIP), to address an error in the specified handling of
> success (200 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.
