The US toll-free number is not accessible from countries outside the United States and Canada, but it is accessible for callers in some other countries that use Skype (as a free call).
Callers can also phone-in from other countries by dialing 847-943-2021, but they will pay a long distance charge to their local phone company. The 847-943-2021 number is a local “land line” Illinois phone number that routes directly to the LifeOnRecord service. It can be called from another country just like any other US telephone number as long as the applicable US Country codes are dialed as well.
In addition, callers can contribute in several other ways as described here.
