A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Session Initiation Protocol Core Working Group of the IETF. Title : Correct transaction handling for 2xx responses to Session Initiation Protocol (SIP) INVITE requests Author(s) : R. Sparks, T. Zourzouvillys Filename : draft-ietf-sipcore-invfix-01.txt Pages : 20 Date : 2010-03-07 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.
