may or may not work, try at your own risk:

1) Use a sip soft phone and set the dtmf mode = inband.
2) In asterisk set the dtmf mode for that soft phone to be rfc2833 or
info. (this is done so that asterisk ignores the inband dtmf on the
sip channel).
3) Design your dialplan such that asterisk should not depend on dtmf
from the sip call.
ex:

exten xxx, 1, dial(zap/g/client_number) //on answer directed to conference room
exten xxx, 2, dial(zap/g/ivr_number) //on answer directed to conference room.
exten xxx, 3, meetme(conference room)

once the sip call is in the conference then the ivr will detect dtmf
from the audio data. Note that before the sip call is in a conference
dtmf will not be detectable by the ivr or asterisk, and Ofcourse, this
is not tested and only a test can confirm if it works.

drawbacks: dtmf will not be available to ivr until your call is in
conference. asterisk will never see any dtmf (which should be okay in
this specific case).
dtmf tones are not squelched so the other user in the conference will
hear dtmf tones.
