Communication lines—whether in offices, boardrooms, or home workspaces—carry some of our most sensitive information. Yet, they remain one of the least protected points in many environments. The REI TALAN 3.0 Telephone & Line Analyzer offers a powerful solution by detecting wiretaps, anomalies, VoIP threats, and suspicious activity across analog and digital wired communication systems.

The TALAN 3.0 is an advanced, multifunctional tool that performs complete analysis of analog, digital, and VoIP communication lines. It's used in corporate security, government facilities, financial institutions, and private investigative work.
All-In-One Line Analysis: Replaces multiple separate tools with a single portable unit that performs electrical testing, spectrum analysis, digital decoding, audio sweep detection, and live waveform monitoring. This consolidation saves time, reduces equipment clutter, and improves reliability of inspections
Detects Analog, Digital & VoIP Threats: The TALAN 3.0 works across classic analog lines and modern digital/VoIP systems. It identifies hidden transmitters, rogue modems, digital carriers, unusual modulation patterns, and suspicious packet activity that older analyzers often miss.
Touchscreen & User-Friendly Interface: Despite being powerful, the device uses a touchscreen interface that keeps common tasks approachable for non-technical users while still offering deep controls for specialists. Corporate buyers appreciate the short training curve and reduced onboarding time.
High-Resolution FFT Spectrum Analysis: FFT (Fast Fourier Transform) spectrum displays provide a visual “X-ray” of what’s on the line—making it easier to spot RF injections, active listening devices, and high-frequency anomalies.
VoIP Packet Capture & Analysis: One of the TALAN 3.0’s standout capabilities is capturing and decoding VoIP packets in real time—allowing detection of covert digital eavesdropping that traditional line testers cannot see.
