ConVox Prison Calling System is a secure, biometric-based communication solution that enables inmates to connect with pre-approved contacts via voice and video calls. Prisoners authenticate themselves using a smart card and fingerprint scan at the kiosk, then press ‘1’ or ‘2’ to call one of two registered numbers—while all other keypad digits remain disabled. The system enforces strict prison authority regulations, including call limitations on frequency, duration, and approved contacts. Calls are recorded, monitored remotely through a centralized server at the state headquarters, and require no internal PCs or cabling in prisons. With online payment integration, inmates can recharge their accounts seamlessly, receiving real-time balance updates after every call. Jail authorities can remotely monitor, generate reports, and ensure secure, transparent, and compliant inmate communication.
