CIS Secure Receives Additional Class A TSG Approvals for Cisco VoIP Phones

Another Industry-first Approval on 8851 10/100/1000 model; Class A Fiber 8841 Also Available

Reston, VA,. October 11, 2016 - CIS Secure is pleased to announce an industry-first Class A TSG type acceptance of a modified general purpose Cisco 8851 VoIP phone (model DTD-8851-02). Tested for compliance and approved by the National Telecommunications Security Working Group (NTSWG), the CIS modified Cisco 8841 VoIP phone also has the distinction of Class B type acceptance (model DTD-8851-01).  Also approved as a Class A device is the fiber enabled Cisco 8841 phone (model DTD-8841-01A1A).

Defined by the Committee on National Security Systems (CNSS), the intent of the NTSWG type-acceptance program is for all telephones used in sensitive discussion areas to be physically incapable of producing any microphonic audio on any wires leaving the instrument while it is in the idle state. Any unmodified VoIP telephone can present eavesdropping vulnerabilities inherent in their Ethernet capabilities. “In the wake of more insider-threat discoveries, NTSWG type-acceptance VoIP phones are all the more crucial to government and commercial markets where information security is paramount”, said John Turner, Chief Technology Officer for CIS. “Our company continues to innovate and develop products that are widely recognized as the most robust and secure solutions in the market”. 

Class A approval is significant because the device is not dependent on other equipment for microphonic security. Class B equipment meets the same testing criteria as Class A equipment with the exception of testing in the powered off state. The powered off test, for Class A Type acceptance, is one of the most difficult to pass. “CIS has patent pending technology that allows our modified Cisco 8851 VoIP phone to pass the TSG Class A requirements using standard copper Ethernet interfaces and infrastructures.” Turner said.  “The fiber-enabled TSG Approved 8841 model addresses the growing use of fiber-to-the-desktop communication infrastructures.”
