         //전화받기
         Intent new_intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
            new_intent.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK)); 
           this.sendOrderedBroadcast(new_intent, null);
            //스피커폰
            AudioManager audio_manager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); 
           audio_manager.setSpeakerphoneOn(true); 

설정값에 따라서.. 5초 10초 20초 기다립니다.!!
그 다음에
//전화받기
//스피커폰전환

저 소스대로 하면 전화가 받아지는데요..
