A toll-free number is a special-number; that enables calls to come in from anywhere without incurring a charge to the caller. The called party pays a toll tariff for the Call. How much the called party pays for a call depends on the arrangements made with the long-distance carrier.
If you look at all of your voice calls and find that majority of them are inbound from customers, you could probably benefit from toll-free service.
For many companies, not having a toll-free number is disastrous. If your car breaks down and you have to call for assistance from a payphone, would you rather pay 50 cents to contact the answering machine of a tow truck or taxi company, or would you call for free? If you’re on hold for a couple of minutes on a toll-free call, at least you’re not paying for it.
