Call from second sim

Question

I have a dual sim android phone. I am using this code to make a call:

private void callBack(String phone, Context context) {         Intent callIntent = new Intent(Intent.ACTION_CALL)                 .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);         callIntent.setData(Uri.parse("tel:" + phone));         context.startActivity(callIntent);      } 

It's working fine. But it always makes call from sim1(preferable sim). How do I make calls from Sim2? Is there a way to handle dual sim phones?
