ABSTRACT:
A processor-controlled automatic calling system is provided in accordance with the teachings of the present invention. The automatic calling system is connected to a plurality of telephone lines within a subscriber's telephone system and all telephone sets within the subscriber's telephone system are monitored for the occurrence of an off hook condition. Upon the occurrence of an off hook condition, a user is permitted a predetermined interval for initiating operation of the automatic calling system through entry of a service code to cause an accessed telephone number and billing code to be outpulsed. In certain embodiments of the invention, an accessing telephone set is muted while the automatic calling system is performing outpulsing functions. Outpulsing functions are preferably performed under the control of a hardware timer to allow additional functions to be performed by a processor on a time-shared basis, and multiple telephone numbers and billing codes may be automatically accessed.
