Call management for secure facilities

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.

A non-transitory computer readable medium for controlling a call in a first controlled facility, the non-transitory computer readable medium comprising computer readable program code for:

• connecting an inmate in the first controlled facility to the call when each party of the call is verified;
• testing first controlled facility incoming audio on the call to detect a first controlled facility tone from a second controlled facility;
• testing second controlled facility incoming audio on the call to detect a second controlled facility tone from the first controlled facility;
• transmitting 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.

A non-transitory computer readable medium for controlling a multiparty call in a detention center, the non-transitory computer readable medium comprising computer readable program code for:

• receiving a request to connect an inmate in the detention center to a plurality of parties in the multiparty call;
• verifying that each party of the plurality of parties is authorized to speak with the inmate;
• verifying that each party of the plurality of parties accepts the multiparty call before being connected to the inmate;
• and
• connecting each party that is authorized and that accepts to the multiparty call;
• wherein incoming audio from the multiparty call includes a detention center coded-pattern multiple notch filter tone;
• wherein incoming audio from a party of the plurality of parties includes a second detention center coded-pattern multiple notch filter tone;
• and
• wherein the detention center coded-pattern multiple notch filter tone is a detention center pre-defined pattern tone and the second detention center coded-pattern multiple notch filter tone is a second detention center pre-defined pattern tone wherein both the detention center pre-defined pattern tone and the second detention center 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.
