CIS Secure Computing, Inc.´s modified general-purpose Avaya 9611G VoIP phone (model DTD-9611G-04) has received Class A TSG-type acceptance by the National Telecommunications Security Working Group (NTSWG), the company said.
The company said the phone also has Class B type acceptance and adds TSG-approved instruments, including phones from Cisco and Polygram, which supports customers migrating to IP telephony.
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 microphonic audio on wires leaving the instrument while it is in the idle state. Any unmodified VoIP telephone can present eavesdropping vulnerabilities inherent in their Ethernet capabilities.
