This TSG Approved VoIP phone is a modified Cisco 8841 version that connects to your network like any other 8841 phone. The difference is the addition of Positive Disconnect On-Hook Security.
Approved for use in SCIF and SAPF environments, the phone also allows the on-hook security features to be engaged while in a call providing enhanced “Hold” and “Mute” security.
