not working with tel selector

I come through https://cfdbplugin.com/?page_id=904 page,
my last lines are as below:

function my_validate_email($result, $tag) {
    $formName = 'form_chk_multi'; // Change to name of the form containing this field
    $fieldName = 'mo_phone'; // Change to your form's unique field name
    $errorMessage = 'This Mobile No. is already Registered with us.'; // Change to your error message
    $name = $tag['name'];
    if ($name == $fieldName) {
        if (is_already_submitted($formName, $fieldName, $_POST[$name])) {
            $result->invalidate($tag, $errorMessage);
        }
    }
    return $result;
}
 
 
// use the next line if your field is a **required text** field
add_filter('wpcf7_validate_tel*', 'my_validate_email', 10, 2);

its not working, i’m using “Shortcodes Actions Filters” plugin with checked “activated status. but when I deactivate this so mail came & entries are also done.
