RFC 3362                MIME Sub-type image/t38              August 2002

   ITU-T Recommendation T.38 [T.38] Annex D describes system level

   requirements and procedures for internet aware facsimile

   implementations and internet aware facsimile gateways conforming to

   ITU-T T.38 to establish calls with other ITU-T T.38 implementations

   using the procedures defined in IETF RFC 2543 [SIP-99] and IETF RFC

   2327 [SDP].

   Note that ITU-T T.38 Recommendation T.38 (04/02) [T.38] is an

   aggregation of the original ITU-T Recommendation T.38 (06/98) [T.38-

   98] and all of the subsequent Amendments and Corrigendum including

   [T.38D-00].  While [T.38] and [T.38D-00] describe SIP procedures per

   [SIP-99], the procedures can also be applied to the revised Session

   Initiation Protocol specification [SIP].
