问题
I'm using this code for calling, in Android application:
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + call.Number));
startActivity(callIntent);
but I obtain a dialog like this:

Why no call is make?
P.s: I'm using a Tablet (Acer Iconia A501), not a smartphone.

Try this
Make sure :
call to :
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" +mEditText_number.getText())));
Add permission:
<uses-permission android:name="android.permission.CALL_PHONE" />
