Call processing with voice over internet protocol transmission
First Claim
1. A call processing system for processing calls associated with a prison facility, comprising:
- a first processor-based system coupled to a plurality of telephone terminals disposed within said prison facility, said first processor-based system transmitting first voice signals associated with one or more of said plurality of telephone terminals, wherein the first processor-based system comprises a first unauthorized call activity detector for monitoring fraudulent or unauthorized call activity associated with the calls; and
a second processor-based system communicating with said first processor-based system via a digital data link and disposed remotely from the first processor-based system, said second processor-based system configured to;
establish calls to called parties requested by the one or more of the plurality of telephone terminals;
convert the first voice signals for transmission over a carrier network responsive to receiving the first voice signals via the digital data link; and
convert second non-VoIP (Voice over Internet Protocol) voice signals from the called parties received via the carrier network to second VoIP voice signals for transmission to the first processor-based system via the digital data link; and
wherein the second processor-based system comprises;
a second unauthorized call detector for monitoring the second non-VoIP voice signals to detect the fraudulent or unauthorized call activity in the calls; and
a call processing platform for validating a billing limit.

Abstract
Disclosed are systems and methods which provide call processing for a plurality of telephones at a site for which calling services are provided. Call control functionality is distributed to remote locations using data networks according to embodiments. The aforementioned data networks and/or separate data networks are used to carry call content using voice over Internet protocols (VoIP). Embodiments utilize VoIP to carry calls from a location at which calling services are provided to a centralized call processing platform providing call processing functionality, such as calling party identification, call validation, call routing, and connection to the public switched telephone network (PSTN). PSTN interfacing by a call processing platform may be provided as a VoIP connection to the PSTN and/or as POTS trunking. Call processing platforms may provide for data sharing, aggregation, and/or analysis across multiple facilities served.

17. A prison facility call processing system comprising:
-
a call processing platform communicating with a plurality of processor-based systems via digital data links, each processor-based system associated with a prison facility, the call processing platform located remotely from at least one of the plurality of the processor-based systems, said call processing platform being coupled to a carrier network and configured to; establish calls from a plurality of telephone terminals in the plurality of process-based systems; receive first voice signals from the plurality of processor-based systems via the digital data links; send the first voice signals over a carrier network to called parties; send second non-VoIP (Voice over Internet Protocol) voice signals from the called parties via the carrier network; convert the second non-VoIP voice signals to second VoIP voice signals for transmission over the digital data links to the plurality of prison facilities; and monitor the second non-VoIP voice signals to detect fraudulent or unauthorized call activity in the calls; and a plurality of call processing gateways, each call processing gateway associated with a prison facility and configured to; process the second VoIP voice signals for transmission to a plurality of telephone terminals in the prison facility and for detecting the fraudulent or unauthorized call activity in the calls, generate the first voice signals responsive to receiving call signals from the plurality of telephone terminals, and validate a billing limit. - View Dependent Claims (18, 19, 20, 21, 22, 29, 32)

23. A method for providing prison facility call processing in a centralized call processing system, said method comprising:
-
communicating with a plurality of processor-based systems via digital data links, each process-based system collecting call signals for establishing calls from telephone terminals in a prison facility, at least one of the processor-based system located remotely from the centralized call processing system; receiving first voice signals collected by one of the plurality of processor-based systems via the digital data link; converting the first voice signals for transmission over a carrier network; receiving a second non-VoIP (Voice over Internet Protocol) second voice signal from the called party via the carrier network; converting the second non-VoIP voice signal to a second VoIP voice signal for transmission over the digital data link to the one of the plurality of processor-based systems and for monitoring fraudulent or unauthorized call activity at the one of the plurality of process-based systems; performing validation of a billing limit; and monitoring the second non-VoIP voice signal for the fraudulent or unauthorized call activity. - View Dependent Claims (24, 25, 26, 27, 30, 33)
