Inbound Resident Call Server Authentication and Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Controlled-environment facilities, such as prisons, typically only allow outgoing communications from inmates, making inbound calls impractical due to the inability to direct calls to the intended inmate and lack of infrastructure for receiving calls.
Innovation Solution
Implementing an inbound resident call server that authenticates non-resident callers and connects them to inmate media and communications devices using an Address Identifier (AID) and personal identification number (PIN), allowing for secure and managed inbound voice or video calls, text messages, and monitoring for impermissible activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional communication services are used in controlled-environment facilities, then outbound calls from inmates are enabled, but inbound calls to inmates cannot be implemented
Solution Approach 1:
The patent inverts the traditional communication model by enabling inbound calls to inmates rather than only outbound calls. The inmate communication device functions as both a calling and called device, allowing reverse communication flow through the same infrastructure that supports outbound calls.
Solution Approach 2:
The inmate communication device is designed with multi-functionality, serving as both an outbound caller and an inbound callee. The same device hardware and software platform that enables inmates to make outbound calls also receives inbound calls, eliminating the need for separate infrastructure.
2Adaptability or versatility
If inbound calls to inmates are enabled, then communication versatility is improved, but call routing precision deteriorates due to inability to direct calls to intended inmate
Solution Approach 1:
The system implements feedback mechanisms where the inmate communication device provides status information (available, busy, in visitation) back to the calling system. This feedback enables intelligent call routing and management, ensuring calls are directed to the intended inmate based on real-time device status and availability.
Solution Approach 2:
The communication system acts as an intermediary between the external calling party and the inmate. It manages call routing, authentication, and connection establishment, ensuring that inbound calls are accurately directed to the intended inmate through centralized control and coordination.
3Reliability
If secure authentication system is implemented for inbound calls, then security is improved, but operation complexity increases
Solution Approach 1:
The authentication system is designed to be self-service oriented, where the inmate communication device automatically performs authentication verification. The device handles PIN entry, identity verification, and security checks autonomously, reducing the operational burden on staff while maintaining high security standards.

AI summary
Sponsorship of controlled-environment facility resident media and/or communications devices by non-residents may include associating a non-resident with an address identifier of a sponsored resident media and/or communications device and associating a controlled-environment facility resident identified by the non-resident with the address identifier of the sponsored device. Thereafter, inbound calls to the sponsored device are connected as a result of confirming that an inbound calling party is associated with the address identifier of the sponsored device and verifying that the resident operating the sponsored device is associated with the address identifier of the sponsored device. Revocation of sponsorship of the sponsored device removes or deactivates association of the non-resident with the address identifier of the sponsored device and removes or deactivates association of the controlled-environment facility resident with the address identifier of the sponsored media and/or communications device.
