Abstract

A secure telephone/computer combination which permits the computer to make automated dialing of a telephone by communicating signals to the interconnection between the telephone'"'"'s number-pad and the electronics which communicate with the telephone line. The computer selects, or the operator directs the computer to select, a telephone number. This selected telephone number is used by the computer to selectively activate the proper connection in the telephone. As example, assume the selected telephone number is 703-305-8062. The computer first sends a signal to the wire connecting the "7" on the keypad to the telephone'"'"'s electronics, then the wire connecting the "0", then the wire connecting the "3", etc. In this manner, the telephone'"'"'s electronics treat the incoming signals in the same manner as if the operator had dialed the number at the telephone. An important attribute of this invention is that while it permits the computer to dial, there is no way a third party can obtain access to the computer via the telephone since there is no communication channel between the two; thereby providing exceptional security for the computer.

Claims

1. A telephone dialing system comprising:

a) a telephone having,

1) a number keypad means for operator entry of values,

2) a dialing circuit means for communicating said values to a telephone line,

3) linkage means for communicating said values from said keypad means to said dialing circuit means, and,

4) a handset for vocal communication via said telephone line;

b) a computer having a memory means for storing at least two series of values; and

,

c) a communication channel for communicating a selected one of said at least one series of values from said memory means to said linkage means.

2. The telephone dialing system according to claim 1 wherein said computer further includes means for isolating said communication channel except during transmission of a selected one of said at least one series of values.

3. The telephone dialing system according to claim 2 wherein said telephone includes an audio interface means for receiving aural signals from a user and for communicating electronic representations thereof to said telephone line.

4. The telephone dialing system according to claim 2 further including a user interface communicating with said computer and wherein said means for selecting includes means for user identification of the selected phone number.

5. The telephone dialing system according to claim 2 wherein said computer includes means for sequentially withdrawing a series of numbers from said memory means.

6. The telephone dialing system according to claim 2 further including means for determining user termination of use of said audio phone channel.

7. The telephone dialing system according to claim 6 wherein said means for sequentially withdrawing is activated by user termination of use of said audio phone channel.

8. The telephone dialing system according to claim 7 further including means for operator disconnection of said audio phone channel from said telephone line.

9. The telephone dialing system according to claim 8 wherein said means for operator disconnection includes speech recognition means.

10. The telephone dialing system according to claim 6 further including a clock and wherein said computer includes means for logging a start and a stop of audio transmission over said audio interface based upon data from said clock.

11. A computer and phone system comprising a housing unit having therein:

a) a phone interface having,

1) an audio circuit communicating with an external telephone line for communicating an audio signal thereto, and,

2) a dialing phone channel communicating with said external telephone line for communicating electronic signals thereto;

b) a handset for audio communications communicating with said audio circuit; and

,

c) a computer having

1) memory means containing a series of phone numbers stored therein, and,

2) means for selecting one of said phone numbers and for communicating the selected phone number to said dialing phone channel.

12. The computer and phone system according to claim 11 further including means for isolating said computer from said dialing circuit during periods of inactivity.

13. The computer and phone system according to claim 12 further including an audio interface for receiving audio signals and for communicating audio signals to said audio phone channel.

14. The computer and phone system according to claim 13 wherein said audio interface is in said housing unit.

15. The computer and phone system according to claim 13 wherein said audio interface is external to said housing unit.

16. The computer and phone system according to claim 12 further including a user interface communicating with said computer and wherein said means for selecting includes means for user identification of the selected phone number.

17. The computer and phone system according to claim 12 wherein said means for selecting includes means for sequentially withdrawing phone numbers from said memory means.

18. The computer and phone system according to claim 12 further including means for determining user termination of use of said audio phone channel.

19. The computer and phone system according to claim 18 wherein said means for choosing is activated by user termination of use of said audio phone channel.

20. The computer and phone system according to claim 18 further including means for operator disconnection of said audio phone channel from said telephone line.

21. The computer and phone system according to claim 20 wherein said means for operator disconnection includes speech recognition means.

22. The computer and phone system according to claim 12 further including a clock and wherein said computer includes means for logging a start and a stop of audio transmission over said audio communication channel based upon data from said clock.
