MEMORY DIALER SYSTEM Abstract The invention is directed to a memory dialer system in which a central memory system is used for all extensions of a particular telephone network. The memory dialer system has a microprocessor and an interface connected with the micro- processor and with a telephone line. A memory is provided in the microprocessor for storing a predetermined number of telephone numbers which include circuitry responsive to selec- tion circuitry for activating the microprocessor to automati- cally dial a selected telephone number. The selection cir- cuitry is operable under control of the telephone extensions. A programmer operable from each of the telephone extensions is also provided to program the memory to store additional telephone numbers for future use. The interface is connected to each extension and a delay circuit is provided to delay a call until a line is cleared if more than two telephone numbers are simultaneously dialed.
