Overview

The Telos Hx1 represents the highest state-of-the-art in hybrid performance, with Telos processing technologies that take the POTS hybrid to a new level of consistently superior performance, regardless of telephone line characteristics. Inside the single-hybrid Hx1, you’ll find advanced hybrid technology with new features that significantly sweeten and control caller audio. It comes standard with Auto-Answer, caller disconnect detection, sophisticated new audio-leveling and anti-feedback routines for enhanced open-speaker applications, call screening and line-hold features, front-panel send and receive audio metering, plus much more.
