Now you can use advanced VoIP technology in TSG-6 on-hook secure applications. Certified by the Committee on National Security Systems (CNSS), Teo TSG-6 on-hook secure IP phones are available for deployment in SCIF (Sensitive Compartmented Information Facility) and SAPF (Special Access Program Facility) secure areas. Teo TSG-6 IP phones are designed to work with all VoIP platforms that support industry-standard SIP protocol.

Teo TSG-6 IP phones meet the stringent requirements specified in the CNSS (Committee on National Security Systems) Instruction No. 5000 and 5001, and have been tested for compliance and approved by the National Telecommunications Security Working Group. TSG-6 Class A versions are not dependent on any other equipment for on-hook security, and may be used in standalone applications within a secure area. The Class B version must be connected to an Ethernet switch collocated within the SCIF. To meet TSG requirements, special positive-disconnect circuitry and ultra low-emissions technology ensures that no microphonic audio signals are produced on any wires leaving the phone when it’s on-hook. Options are available for TSG-6 Class A or Class B applications; 802.3af Power over Ethernet (PoE) or local power; and switched Ethernet port for PC connection.
