Actually it would be very easy.  If you get back a DTMF frame while
playing audio, simply return the value of the DTMF frame, something like

while(playing audio and not hungup yet) {
	res = ast_waitfor(chan, how long i need to wait);
	f = ast_read(chan);
	if (!f) { res = -1; break; }
	if ((f->frametype == AST_FRAME_DTMF))
		return f->subclass;
