First, the reference I-D has become RFC3265, see http://www.ietf.org/rfc/rfc3265.txt
Second, RFC2833 specifies how telephony tones are sent using RTP. If your question deals with the use of DTMF as a means for users to interact with services, then the direction being worked in the SIPPING working group of the IETF is described in http://www.ietf.org/internet-drafts/draft-rosenberg-sipping-app-interaction-framework-00.txt and a couple related I-Ds.
I have seem some indication that a SIP Events package may be receiving some re-consideration for "DTMF". However, I myself have not seen anymore information on this on the relevant working group mail list.
Best regards, Bert

Does anyone have any insight as to the pros or cons of each of these methods and which is the preferable for the foreseeable future? I am running into multiple vendors lauding one way over another, but I can not find any concrete information as to the real benefits of one over the other. Also, I haven't seen an updated version to the draft Roach beyond 3, does anyone know if there is a more recent one that hasn't expired?
Thanks
James Walker.
