But if that's not the case, you're looking at a noticeable hike in billing. For example, for an average 3-minute call, your per call costs will nearly double. It can also affect your business if you use a toll-free number to access services such as a pager or voice mail service. These companies have responded by blocking calls made from pay phones or adding these charges to the bill. As a toll-free number owner, if the pay phone calls you receive represent a cost you are unwilling to bear, you can ask your carrier to block these calls.
Call blocking can come at a price, though.
While some companies do it for free, others charge both a set-up and a monthly fee for this privilege. In addition, not every long-distance carrier can support call blocking. If you want to avoid paying for pay phone calls, you'll need to switch carriers. Well, right now, not every pay phone is equipped to pass on these charges. The same long-distance companies are contesting the latest ruling.
