The Protego PTG400 is a TAA-compliant USB handset designed as a lightweight, ergonomic alternative to headsets for softphone applications like Microsoft Teams and Zoom. This plug-and-play device supports Windows and MacOS via a 1.5-meter USB-A or USB-C cable and includes an adjustable desktop cradle. For secure environments, the PTG400-SEC model features an integrated Push-To-Talk (PTT) button to ensure background conversations are not inadvertently overheard during calls.
