Abstract

The present subject matter is directed to an apparatus and methodology for recording, at a central data center, telephone conversations originating from remote locations. The present subject matter has particular utility to the penal (corrections) environment in that it discloses a methodology for recording and storing voice and related data at a central data center remote from either the origination or destination locations of a telephone call placed by an inmate in a prison or other facility. The disclosed technology permits storage of both voice and call related data at a remote facility in such a manner that the data is searchably accessible by authorized personnel at other remote locations by way of network or Internet connection to the central data center.

Claims

1. An audio recording system, comprising:

a first telephone instrument located at a first location within a prison environment and configured for communications with a second telephone instrument located at a second location remote from said first location;

an analog to digital converter at said first location, having an input and an output, said first telephone instrument coupled to said input of said analog to digital converter; and

a data storage device located at a third location physically remote from said first location and said second location, said data storage device coupled to said output of said analog to digital converter, whereby conversation data from conversations conducted by way of said first telephone instrument may be recorded and stored at said third location physically remote from said first location and said second location.

2. An audio recording system as in claim 1, further comprising:

a wide area network coupled between said analog to digital converter and said data storage device.

3. An audio recording system as in claim 1, further comprising:

a data compressor coupled to said output of said analog to digital converter.

4. An audio recording system as in claim 1, further comprising:

a workstation coupled to said data storage device and configured to access recorded conversation data stored in said storage device.

5. An audio recording system as in claim 4, wherein said workstation is coupled to said storage device via a wide area network, and wherein said workstation is configured to search accessed recorded conversation data.

6. An audio recording system as in claim 1, further comprising:

a workstation coupled to said analog to digital converter and configured to access ongoing conversations.

7. An audio recording system as in claim 6, wherein said wide area network is the Internet.

8. An audio monitoring and recording system, comprising:

a first telephone instrument located at a first location within a prison environment and configured for communications with a second telephone instrument located at a second location;

an analog to digital converter at said first location having an analog input and a digital output, said first telephone instrument coupled to said input of said analog to digital converter;

a storage device located at a third location physically remote from said first location and said second location coupled to said output of said analog to digital converter, said storage device being configured to store recorded conversation data files corresponding to said digital output of said analog to digital converter;

a streaming converter coupled to said storage device; and

a workstation coupled to said streaming converter,

whereby audio originating from said telephone instrument may be monitored at said workstation.

9. An audio monitoring and recording system as in claim 8, wherein said streaming converter may be selectively coupled to said output of said storage device whereby a previously recorded conversation may be monitored.

10. An audio monitoring and recording system as in claim 8, wherein said streaming converter may be selectively coupled to said output of said analog to digital converter whereby an ongoing conversation may be monitored.

11. An audio monitoring and recording system as in claim 8, wherein conversation identifying data is associated with said recorded conversation data files stored on said storage device, and wherein said workstation is configured to perform logical searches of said conversation identifying data.

12. An audio monitoring and recording system as in claim 8, wherein said workstation is configured to perform searches of said conversation data.

13. An audio monitoring system as in claim 12, wherein said workstation is coupled to said streaming converter by way of a wide area network.

14. An audio monitoring and recording system as in claim 13, wherein the wide area network is the Internet.

15. An audio retrieval system, comprising:

a storage device configured to store data files corresponding to recorded conversations conducted between a first telephone instrument at a first location within a prison environment and a second telephone instrument at a second location, said storage device being located at a third location remote from both said first and second locations;

a streaming converter coupled to said storage device; and

a workstation remotely located at a fourth location remote from each of said first, second, and third locations coupled to said streaming converter, whereby audible reproductions of said recorded conversations may be monitored at said workstation.

16. An audio retrieval system as in claim 15, wherein conversation identifying data is associated with said data files stored on said storage device and said workstation is configured to perform logical searches of said conversation identifying data.

17. An audio retrieval system as in claim 15, wherein said workstation is configured to perform searches of said data files.

18. An audio retrieval system as in claim 15, wherein said workstation is coupled to said streaming converter by way of a wide area network.

19. An audio retrieval system as in claim 18, wherein the wide area network is the Internet.

20. A specialized phone system for use in relation to a prison environment, having an audio recording system, comprising:

a first telephone instrument located at a first location situated within a prison facility and configured for communications with a second telephone instrument located at a second location remote from said first location;

an analog to digital converter at said first location, having an input and an output, said first telephone instrument coupled to said input of said analog to digital converter; and

a data storage device located at a third location comprising a defined central data center physically remote from both said first location and said second location, said data storage device coupled to said output of said analog to digital converter, whereby inmate conversation data from inmate conversations conducted by way of said first telephone instrument may be recorded and stored at said central data center physically remote from said prison facility.

21. A specialized phone system as in claim 20, further comprising:

a wide area network coupled between said analog to digital converter and said data storage device.

22. A specialized phone system as in claim 20, further comprising:

a data compressor coupled to said output of said analog to digital converter.

23. A specialized phone system as in claim 20, further comprising:

a workstation coupled to said data storage device and configured to access recorded inmate conversation data stored in said storage device.

24. A specialized phone system as in claim 23, wherein said workstation is coupled to said storage device via a wide area network, and wherein said workstation is configured to search accessed inmate recorded conversation data.

25. A specialized phone system as in claim 20, further comprising:

a workstation coupled to said analog to digital converter and configured to access ongoing inmate conversations.

26. A specialized phone system as in claim 20, further comprising:

a streaming converter coupled to said data storage device; and

a workstation coupled to said streaming converter,

whereby inmate conversations originating from said telephone instrument may be monitored at said workstation.
