ABSTRACT:
Using designated special telephone numbers each associated with a particular language to provide rate information by a telecommunication switching system that responds to those special telephone numbers. When a caller calls one of the special numbers, the caller is requested in the correct language to enter the desired destination telephone number; and in return, the caller receives the cost for making a call to that number. If the caller wishes to place the call, the system automatically places the call. If the decision is made to place the call, an option allows the caller to specify the maximum amount of money they will spend. After this maximum amount of money is met, the system automatically disconnects the call. The system gives a warning at some predetermined interval before the call is disconnected. In addition to the rate information for making the call at the present time, system provides the caller with the cheapest time to make the call and the present time and day for the location of the destination telephone number.
