The T.38 recommendation defines how T.30 negotiations are carried in IFP
(Internet Fax Protocol) packets; the definitions of the actual frames
are in the T.30 recommendation itself.

T38 rfc does not detail the sequence of t30 negotiations..
Like v21 preamble, nsf, Dsi, what the correct sequence of t30  
negotiation. Is.
