ABSTRACT:
A method and system for automatically completing international telephone calls using a pre-selected discount telephone service. An array of Pic I/O pin used to monitor a cell phone activity. When the dialing of an outgoing call is detected, a central processing unit, in conjunction with a DTMF decoder, determines whether the call being made is a discount call by detecting whether predetermined positioned digit(s) is a predetermined number or set of numbers. If the number dialed is a potential discount call, the DTMF generator dials a predetermined discount service provider number and/or access code resulting in completion of the call at a discounted rate.
