Sectéra vIPer Phone ready to replace all Secure Telephone Units (STU-IIIs) that reached end-of-life in December 2009.

The National Security Agency (NSA) has certified the Sectéra vIPer Universal Secure Phone enabled with Public Switched Telephone Network (PSTN) connectivity for voice communications classified at the Top Secret level and below. The Sectéra vIPer Phone with PSTN Connect allows U.S. military and government personnel to make both classified and unclassified calls using traditional telephone networks via one high-end office desktop phone. The Sectéra vIPer Phone is a secure communication product manufactured by General Dynamics C4 Systems, a business unit of General Dynamics (NYSE: GD).

"The certification makes the vIPer Phone with PSTN Connect a cost-effective solution as users will no longer have support and maintenance of their legacy Secure Telephone Units or STU-IIIs," said John Cole, vice president of Information Assurance for General Dynamics C4 Systems. PSTN and VoIP network flexibility, combined with the vIPer Phones interoperability with the government's Secure Terminal Equipment (STE), also enables customers to easily transition to the latest technology.

Introduced in 2006, the Sectéra vIPer Phone remains the only Voice over IP Phone certified by the NSA to protect voice communications classified Top Secret and below over commercial, wired VoIP networks. As military and government organizations plan for evolving technology and the replacement of end-of-life STU-III phones, General Dynamics is offering a price discount of $200 for each vIPer Phone ordered to replace a deployed STU-III or STE phone.
