Vertical has evolved from the combination of four leading technology and phone system vendors and the creation of one of the industry´s leading IP telephony research and development teams. Vertical´s journey began in 2004 with the entrance of Vertical´s current management team and group of investors. The team combined the Artisoft and Vertical Networks businesses and completed a related financing transaction in September 2004. With new investors and a large infusion of capital, the management team set out to build a world-class IP telephony company and distribution channel.
A year later, Vertical completed the acquisition of Comdial Corporation and thereby introduced a new family of products to a much expanded Vertical channel. In December 2006, Vertical took the next significant step in its growth by acquiring Vodavi Technologies, Inc. and forming a strategic relationship with LG-Ericsson, including LG-Ericsson´s ownership of 11 percent of Vertical´s shares outstanding. The combination of these efforts has led to Vertical´s ranking as a top-five telephony vendor serving the SMB market in North America.
