Using a calling card issued by your long distance carrier is not always the cheapest option. Even when you factor in volume discounts, cards from other carriers are often much less expensive.

Local cards
Travelers who make most calls within one area code should consider a calling card offered by the local telephone company. These carriers usually provide better rates for calls placed in the local region. A secondary benefit is typically shorter access codes.

Multiple call feature
Some calling cards waive the access surcharge for subsequent calls when multiple calls are placed at a time. Inquire about the availability of this feature.

Handling multiple cards
If you issue calling cards to employees, do not share cards or a single account code. Issuing unique accounts to each person will make it much easier to activate and deactivate cards as individuals leave the firm.
