How do I allow the user to select from the list to make a call

Question

String [] AgricultureNumbers ={
        "Administration           347-648-2999 ",
        "Legal office             347-895-3456",
        "Permanent Secatery       347-852-6665"
};
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,AgricultureNumbers);
        setListAdapter(adapter);

    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "347-648-2999"));
        startActivity(intent);
    }

}

I want the user to call the item selected number, but it only call the 347-648-2999..Any help will be appreciated.
