REDCOM Sigma is REDCOM’s flagship unified communications (UC) and call control software platform focusing on secure and interoperable communications. The software can function as a stand-alone virtualized 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.
REDCOM Sigma delivers powerful capabilities highly relevant to the government and military, including a robust URI-based call routing engine with full support for the Assured Services Session Initiation Protocol (AS-SIP). The software offers a comprehensive set of UC functions, including VoIP, point-to-point video, XMPP with presence, conferencing, and unified messaging.
REDCOM Sigma version 2.0.3 is currently on the DISA Approved Products List (APL).
