我想拒绝某个特定号码的来电，但它不起作用

我想阻止特定号码的来电。首先我尝试所有来电。它运作良好。但是当我尝试特定数量由下面的代码调用不拒绝，电话响起，我试图用我的Android手机..我想拒绝某个特定号码的来电，但它不起作用

 @Override 
    public void onReceive(Context context, Intent intent) { 
     Log.v(TAG, "Receving...."); 
     String t1="01741297163",t2="08801741297163"; 
     TelephonyManager telephony = (TelephonyManager) 
     context.getSystemService(Context.TELEPHONY_SERVICE); 
     try { 
     Class c = Class.forName(telephony.getClass().getName()); 
     Method m = c.getDeclaredMethod("getITelephony"); 
     m.setAccessible(true); 
     Bundle b=intent.getExtras(); 
     num=b.getString(telephony.EXTRA_INCOMING_NUMBER); 
     if(num.equals(t1)||num.equals(t2)){ 
     telephonyService = (ITelephony) m.invoke(telephony); 
     //telephonyService.silenceRinger(); 
     telephonyService.endCall(); 
     } }catch (Exception e) { 
     e.printStackTrace(); 
     }

我不知道来电号码的格式从获得电话管理员。
