Abstract

A system for controlling and monitoring the recording of telephone calls in institutions such as jails and correctional facilities. Calls are recorded automatically in response to the occurrence of specific triggering events, as pre-defined under software control by a system administrator. Triggering events may include, for example, use of a specific line, attempts to use particular features (such as three-way calling), attempts to dial particular telephone numbers, or use by a particular person. Recorded calls are digitized and stored in standard MS-DOS files on either a local computer system or a remote computer across a network. Stored digitized recordings may be selected for playback under software control by a system administrator. The system of the present invention allows control of recordings from within a conventional telephone system. The integrated nature of the system provides cost savings and improved flexibility.

Claims

1. A telephone system for selectively blocking or recording outgoing telephone calls, comprising:

a parameter input device for specifying one or more block parameters to identify unauthorized calls and one or more record parameters to identify calls for recording;

a processor coupled to the input device and to a telephone line of the telephone system, the processor including a control program for continuously monitoring the telephone line for call parameters and comparing the specified block and record parameters with detected call parameters;

switching means coupled to the processor, the telephone line, and outside telephone lines for blocking an outgoing telephone call when a detected call parameter matches a specified block parameter; and

a recording device coupled to the processor for recording conversations on the telephone line when a detected call parameter matches a specified record parameter and no detected call parameter matches a specified block parameter.

2. The system of claim 1, wherein each specified parameter is a call parameter that is generated by a triggering event.

3. The system of claim 2, wherein the triggering event is usage of a specified telephone line.

4. The system of claim 2, wherein the triggering event is an attempt to dial a specified telephone number.

5. The system of claim 2, wherein the triggering event is a telephone call having a length exceeding a predefined amount of time.

6. The system of claim 2, wherein the triggering event is an attempt to use a specified telephone feature.

7. The system of claim 6, wherein the specified telephone feature is three-way calling.

8. The system of claim 6, wherein the specified telephone feature is call-forwarding.

9. The system of claim 1, further comprising counting means coupled to the processor for counting a number of occurrences of a specified event on the telephone line, wherein a specified record parameter comprises a specified number of occurrences of the specified event.

10. The system of claim 9, wherein the specified event is an attempted call to a specified number.

11. The system of claim 9, wherein the specified event is a completed call to a specified number.

12. The system of claim 9, wherein the control program monitors the telephone line for a user ID and the specified event is the detection of an ID of a specified user.

13. The system of claim 1, further comprising a storage device coupled to the recording device for storing recorded conversations.

14. The system of claim 13, further comprising an access device coupled to the storage device for selectively accessing stored conversations.

15. The system of claim 13, wherein the storage device stores recorded conversations in a digitized format.

16. The system of claim 1, further comprising counting means coupled to the processor for counting a number of occurrences of a specified event on the telephone line, wherein a specified block parameter comprises a specified number of occurrences of the specified event.

17. The system of claim 16, wherein the specified event is the detection of an attempted call to a specified telephone number.

18. The system of claim 16, wherein the control program monitors the telephone line for a user ID and the specified event is the detection of an ID of a specified user.

19. A computer-implemented process for selectively blocking or recording outgoing telephone calls, comprising the steps of:

specifying block and record parameters for identifying outgoing telephone calls to be blocked or recorded, respectively;

continuously monitoring an outgoing telephone call for call parameters generated by the outgoing telephone call;

comparing the specified block and record parameters with detected call parameters;

blocking the outgoing telephone call when a detected call parameter matches a specified block parameter; and

recording the outgoing telephone call when a detected call parameter matches a specified record parameter and no detected call parameter matches a specified block parameter.

20. The computer-implemented process of claim 19, wherein each specified parameter is a call parameter that is generated by a triggering event.

21. The computer-implemented process of claim 19, further comprising the step of counting a number of occurrences of a specified event on a telephone line, wherein the step of specifying a record parameter comprises the substep of specifying a number of occurrences of the specified event.

22. The computer-implemented process of claim 19, further comprising the step of storing the recording of the telephone call in a digitized format.

23. The computer-implemented process of claim 22, further comprising the steps of:

accepting a request to play back a recorded telephone call; and

playing back the requested telephone call.

24. The computer-implemented process of claim 19, further comprising the steps of:

digitizing the recorded telephone call; and

storing the digitized telephone call.

25. The computer-implemented process of claim 24, further comprising the steps of:

storing descriptive information regarding the recorded telephone call; and

selectively displaying the stored descriptive information.
