   Hack the area around line 1825 of apps/app_dial.c (going off of 1.4.3):

--- SNIP (reformatted) ----
    if (ast_test_flag(peerflags, OPT_CALLER_HANGUP) &&
          (f->subclass == '*')) {
     /* hmm it it not guaranteed to be '*' anymore. */
     	if (option_verbose > 2)
 		ast_verbose(VERBOSE_PREFIX_3 "User hit %c to disconnect call.\n", f->subclass);

 	*to=0;
 	strcpy(status, "CANCEL");
 	ast_frfree(f);
         return NULL;
     }
}
-------------

   Inside the higher-order if block:

 	if(f && (f->frametype == AST_FRAME_DTMF)) {

 	...

   Make it so it accumulates states of at least two contiguous 
DTMF-containing frames and makes the inference if they come within a 
certain interval of each other.
