Abstract

Disclosed are systems and methods which provide a centralized architecture for call processing. Embodiments utilize voice over Internet protocols (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). Call processing gateways may be utilized to provide plain old telephone service (POTS) analog line interfaces for use with a plurality of telephone sets disposed for use at a location and at least one wide area network (WAN) interface for providing high speed data communication to a centralized call processing platform. 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.

Claims14

Dependent claims

A centralized call processing system, comprising:

a networking device connected to a plurality of call processing gateways of a plurality of prison facilities located remotely from the centralized call processing system via a wide area network (WAN), the networking device configured to:
receive outgoing Voice over Internet Protocol (VoIP) data packets from prison facilities;
and
send incoming VoIP data packets to the prison facilities;
an unauthorized call activity detection system connected to the networking device for detecting three-way call activity associated with the outgoing VoIP data packets or the incoming VoIP data packets via a local area network (LAN);
a call application management system connected via the LAN to the networking device for processing the outgoing VoIP data packets for transmission to a telephone carrier network, the call application management system processing signals from the first telephone carrier network into the incoming VoIP data packets;
and
a validation system connected via the LAN to the call application management system and configured to allow or disallow completion or continuing of a particular call of the plurality of prison facilities through the telephone carrier network based on the outgoing VoIP data packets or the incoming VoIP data packets.
