5. The apparatus of claim 4 , wherein obtain the voiceprint and verify the inmate is authorized is performed periodically for each party of the call throughout the call.

6. The apparatus of claim 1 , wherein the software application, physically stored in the memory, further comprises instructions to cause the at least one processor and the apparatus to:

analyze a discussion performed over the call to determine a subject matter of the discussion;

determine, based on the subject matter, whether a second violation is occurring;

transmit a notification of the second violation when a second violation is occurring.

7. The apparatus of claim 1 , wherein the software application, physically stored in the memory, further comprises instructions operable to cause the at least one processor and the apparatus to:

analyze a discussion performed over the call to determine a subject matter of the discussion;

determine, based on the subject matter, whether a crime is being discussed;

transmit a transcript of the call to an investigator when a crime is being discussed.

8. The apparatus of claim 1 , wherein the software application, physically stored in the memory, further comprises instructions operable to cause the at least one processor and the apparatus to:

obtain connection parameters from the call;

perform data mining on connection parameters to determine whether the call violates a rule; and

transmit a notification of the a violation when the call violates a rule.

9. A system for controlling a call in a first controlled facility, comprising:

a computer processor; and

a network application executing on the computer processor and comprising:

a connection module configured to connect an inmate in the first controlled facility to the call when each party of the call is verified; and

a call analysis module configured to:

test first controlled facility incoming audio on the call to detect a first controlled facility tone from a second controlled facility,

test second controlled facility incoming audio on the call to detect a second controlled facility tone from the first controlled facility, and

transmit a notification of a first violation by the inmate when the first controlled facility tone is detected in the incoming audio;

wherein the first controlled facility tone is a first coded-pattern multiple notch filter tone;

wherein the second controlled facility tone is a second coded-pattern multiple notch filter tone; and

wherein the first coded-pattern multiple notch filter tone is a first pre-defined pattern tone and the second coded-pattern multiple notch filter tone is a second pre-defined pattern tone wherein both the first and second pre-defined pattern tones are detectable, when both are present on the incoming audio, via bi-modal telephony band pass edge filtering of the incoming audio.

10. The system of claim 9 , wherein the call analysis module is further configured to:

generate a call fingerprint from audio in the call;

compare the call fingerprint with a plurality of call fingerprints from a plurality of controlled facilities; and

transmit a notification of a second violation when the call fingerprint matches at least one of the plurality of call fingerprints tone.

11. The system of claim 9 , wherein the network application further comprises:

a party verification module configured to:

verify each party to the call by:

obtaining an owner of a telephone number of each party to the call; and

verifying that the inmate is authorized to communicate with the owner,

wherein connection of the telephone number to the call is denied when the inmate is not authorized to communicate with the owner.

12. The system of claim 9 , further comprising:

a datacenter server storing a party voiceprint data relating a party to a voiceprint,

wherein the call analysis module is further configured to:

for each party of the call,

obtain, during the call, the voiceprint of the party; and

verify that the inmate is authorized to communicate with the party having the voiceprint using the party voiceprint data,

wherein connection of the party to the call is suspended when the inmate is not authorized to communicate with the party based on the voiceprint.
