Sorry - my bad - dtmf-type looks like it just controls what's sent,  
not what's received.
Brian's advice is sound, or you can probably work around things right  
now by editing
src/mod/endpoints/mod_sofia/sofia.c - at around line 3838 you'll find:
if (dtmf.digit) {
   /* queue it up */
   switch_channel_queue_dtmf(channel, &dtmf);
..more code..
   /* Send 200 OK response */
   nua_respond(nh, SIP_200_OK, NUTAG_WITH_THIS(nua), TAG_END());

- lose the bit which handles the SIP INFO DTMF by adding a couple of  
lines thusly:
if (dtmf.digit) {
#if 0
   /* queue it up */
   switch_channel_queue_dtmf(channel, &dtmf);
..more code..
#endif
   /* Send 200 OK response */
   nua_respond(nh, SIP_200_OK, NUTAG_WITH_THIS(nua), TAG_END());

It's a nasty hack, but it just might work.
