The Cellcrypt Enterprise Gateway enables users to securely call office desk phones from a cell phone. New from London-based Cellcrypt, the system is designed for use by senior executives traveling to hostile countries where phone interception is widespread. The software application interfaces with office phone systems and provides encrypted voice calling to BlackBerry and Nokia mobile phones running the Cellcrypt Mobile software. It also passes commands to and from phone systems via keypad tones and interactive commands to enable secure remote access to features such as conference calling. Using the IP data channel, it supports all major wireless networks, including 2G, 3G, Wi-Fi, and satellite. The encryption technology is compliant with the FIPS 140-2 security standard.
