Phone Line Sweep (Analog, Digital & VoIP)
Wiretaps on fixed telephony remain among the most silent forms of corporate interception. With the REI TALAN 3.0, SCS Detect inspects analog, digital (PBX) and VoIP lines, plus wiring, to detect and locate wiretaps, taps and anomalies — documenting the exact position of the threat on the cable.
In short
SCS Detect's phone-line sweep detects wiretaps and taps on analog, digital (PBX) and VoIP lines using the REI TALAN 3.0. Electrical measurements and reflectometry (FDR) pinpoint the exact position of the threat on the cable, with a technical report. Service across São Paulo, Rio and Brasília, response within 4 hours.

Why fixed telephony is still a target
Boardrooms, negotiation tables and executive offices keep fixed extensions — and a well-installed tap can operate for years unnoticed. Inspection requires dedicated instrumentation: precision electrical measurements, signature comparison and end-to-end wiring analysis.
Does the sweep interrupt the phone lines?
There's no need to shut down the whole operation. We work with the REI TALAN 3.0 in agreed windows, measuring line by line with minimal impact. For critical environments, we schedule outside peak hours.
Are VoIP taps detectable too?
Yes. We inspect analog, digital (PBX) and VoIP lines, plus wiring. With VoIP the vector changes — we combine electrical measurements, spectrum analysis and verification of the wiring and associated network points to identify taps and anomalies.
