IP telephony solution provider Network Equipment Technologies, Inc. has reportedly completed the preliminary interoperability testing between its Voice Exchange (VX) Series and General Dynamics secure telephony devices.

 

General Dynamics C4 Systems (News - Alert) is a provider of secure communication and information systems and technology. According to the company, this successful testing with NET’s VX series of integrated switch gateways demonstrates the Sectéra vIPer Secure Phone's ability to communicate between IP networks and secure communications devices on analog networks.

 

This interoperability will eventually allow users of the soon-to-be-released Session Initiation Protocol (News - Alert) (SIP) version of vIPer to communicate with various existing analog products.

 

NET's (News - Alert) Voice Exchange (VX) Series is the IP telephony platform that allows public and private network operators to leverage the benefits of unified messaging and unified communications and simplifies the network by combining their PBX (News - Alert) voice traffic onto a single converged data network.

 

Precisely, the testing is stated to have involved NET's VX900 with the V.150 Universal Modem Relay technology to demonstrate interoperability the includes; SIP vIPer with secure wireless devices such as the Sectéra Edge Smartphone and the Sectéra Secure GSM phone over a number of cellular carriers' networks; SIP vIPer to the PSTN vIPer; SIP vIPer to the Secure Terminal Equipment (STE); SIP vIPer to the Sectéra Wireline Terminal.

 

Reportedly, in 2006, the Sectéra vIPer phone was certified by the National Security Agency (News - Alert) (NSA) to protect information classified Top Secret and Below over Skinny Call Control Protocol (SCCP) VoIP networks for authorized U.S. military and government users. Additionally, the company is also expected the certification by the NSA of the Sectéra vIPer for use over SIP VoIP networks. In January 2009, the PSTN capability of the Sectéra vIPer phone was also certified by the NSA.

 

"This technology will enable interoperability with secure voice devices and legacy equipment as more customers migrate to SIP phones, softphones and PC-based voice devices," said Talbot Harty, chief development officer at NET.

 

The V.150 capability, when combined with the VX Series' existing ability to support TDM-based Secure Communications Interoperability Protocol (SCIP) phones, is said to offer instant interoperability between old and new technologies. Further, NET's V.150 solution includes the company's Bestflow frame-packing technique, which allows VoIP to traverse firewalls, and also offers bandwidth-saving capabilities and numerous features that protect the reliability of secure telephony over IP, said NET’s official.
