A UA that doesn't obey Record-Route is likely to fail in any situation requiring gatewaying or NATing. So I would tend to say "tell your customers to not buy such phones, as they won't work reliably". If you have to deal with such UAs (or UAs that are downright hostile), you will have to hide the Contact address, and the Via addresses as well.
