   Really?

ORLY?

   http://www.google.com/search?q=site%3Atools.ietf.org+%22application%2Fdtmf%22

   ...and, lest there be any confusion about how far back that archive goes:

       http://tools.ietf.org/html/draft-ietf-mmusic-sip-01

I'm not sure what that search does, but it doesn't turn up the
document you're looking for, viz.:
http://tools.ietf.org/html/draft-ietf-mmusic-sip-info-method-00, which
proposed a new SIP method "INFO" to carry DTMF digits and such
information:

    Abstract

    This document proposes an extension to the Session Initiation
    Protocol.  This extension adds the INFO method to the SIP protocol.
    The intent of the INFO method is to allow for the carrying of session
    related control information that is generated during a session.
    Examples of such session control information are ISUP/ISDN signaling
    messages and DTMF digits used to control telephony services.
