REDCOM Call Control Portfolio and REDCOM Secure Client Recertified by DoD’s Joint Interoperability Test Command

January 18, 2019

REDCOM, a leading provider of advanced tactical and strategic communications solutions, proudly announces that three of its products focused on Cyber Security (CS) and Interoperable (I/O) communications have been officially recertified by the Joint Interoperability Test Command (JITC) and placed on the Department of Defense Information Network Approved Products List (APL).

HDX V4.0AR5P1, SLICE® V4.0AR5P1, and REDCOM Sigma® 2.1.1 have all been carefully evaluated and approved as Local Session Controllers (LSC). All three products deliver powerful capabilities highly relevant to the military, including support for the Assured Services Session Initiation Protocol (AS-SIP), IPv4/IPv6 dual stack, Multi-Level Precedence and Preemption (MLPP), conferencing, and secure communications.

HDX and SLICE® are REDCOM’s hybrid hardware platforms that enable seamless interoperability between IP, TDM, and radio networks. Sigma is REDCOM’s flagship military-grade software call control platform that delivers robust call control, media handling, and encrypted communications. REDCOM systems can function as a stand-alone Local Session Controller (LSC) or as an adjunct to an existing Enterprise Session Controller (ESC) to deliver advanced voice services such as transcoding and conferencing for red and black networks.

As part of the testing, the REDCOM Secure Client for Windows® 4.1.2 has been certified with REDCOM Sigma, REDCOM HDX, and REDCOM SLICE. The REDCOM Secure Client has features and capabilities particularly useful for government and military users including MLPP, FIPS 140-2 validated encryption and dual registration for survivability.

REDCOM’s JITC-approved products deliver military-grade resiliency designed for deployments to the tactical edge. All REDCOM technology is based on open SIP standards, which eliminates proprietary endpoints and applications.
