August 1, 2022

REDCOM, a leading provider of advanced tactical and strategic communications solutions, proudly announces that REDCOM Sigma software version 3.1.1 has been officially certified by DISA and placed on the Department of Defense Information Network Approved Products List (APL).

REDCOM Sigma® 3.1.1 has been carefully evaluated and approved as a Local Session Controller (LSC). Sigma is REDCOM’s flagship military-grade software Command and Control (C2) platform that delivers voice, video, chat, and radio interoperability in one software instance. In addition to UX improvements and conferencing enhancements, Sigma 3.1 includes two major new features: the REDCOM C2 Console app and TSM talk group support. REDCOM Sigma 3.1 further increases the warfighter’s operational flexibility while reducing complexity and lifecycle costs.

Sigma is based on open SIP standards, which eliminates proprietary endpoints and applications. Sigma 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.

Sigma software is already deployed and proven in multiple programs with the U.S. Army and U.S. Air Force.

This latest DISA cybersecurity (CS) and interoperability (IO) certification for REDCOM Sigma is valid through September 24, 2024.
