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:
It gives DTMF as an _example_ of the kind of information that might be carried by INFO. It doesn't give even the remotest amount of technical detail about how one might do so.
At the time, there was an ensuing debate about the appropriateness of using INFO in this way, in which we developed a consensus that INFO really isn't the right tool for the job.
Unfortunately, when the naive answer is also the wrong answer, it seems impossible to ever put a decision to bed -- which is why we now hear the slow "clack... clack... clack" of the whole working group going up the initial slope of the "DTMF in INFO argument" roller coaster for the hojillionth time. Hold on tightly; it's not a fun ride...
