Abstract
A computer implemented method is disclosed for automatically intercepting and analyzing computer modem commands for toll characteristics andthen alternatively permitting or preventing the computer modem command based on the results of the toll analysis and user preferences. The computer modem command is analyzed by extracting any proposed telephone dialing instructions and comparing the proposed telephone number to be dialed with data provided by the local telephone service provider (TSP) in order to determine whether the proposed telephone number would result in a “toll call,” or telephone service charges over and above the usual monthly rate, if transmitted to the modem. If a telephone service charge would result, the computer user is notified and prompted to give further instructions concerning whether the toll call should be placed.
