Standardization of mechanisms on sending DTMF in INFO has not occurred. For SIP, the use of DTMF is seen as a means for user interaction with network-based applications. To this end, work is ongoing on to define a framework and mechanisms for users to interact with applications in SIP. See the I-Ds below for how this is expected to be supported.
