DiVitas combines corporate voice and messaging applications for business and places them onto a single mobile smartphone under IT control.  As a result, employees are reachable via a single business number – their deskphone extension – anywhere, anytime. They also have access to a broad set of business communications features designed to enhance the efficiency of mobile business communications. These capabilities are made available reliably and cost-effectively over both cellular and WiFi networks using Environment Aware Roaming Technology. DiVitas consists of two key components:  the DiVitas Client and the DiVitas Server.
