I want to set one number to default in android contact, but I don't know what I should write in place of Phone.NUMBER?

ContentResolver cr = this.getContentResolver();

Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projectionPhones,
    ContactsContract.CommonDataKinds.Phone.NUMBER +"=?", new String[]{"09183332222"}, null);

while(pCur.moveToNext())
{
    tv.setText(pCur.getString(1));
}

ContentValues values = new ContentValues();
values.put(Phone.DISPLAY_NAME, "Test");

// values.put(Phone.NUMBER  ,numberToCall);

values.put(Phone.NUMBER, numberToCall);

int phones = getContentResolver().update(ContactsContract.RawContacts.CONTENT_URI,values,
    Phone.CONTACT_ID +" = 1812", null);
