One Communications Selects VeriSign to Be Premier Provider of SS7 and Database Services

MOUNTAIN VIEW, CA (Marketwire) - VeriSign, Inc. (NASDAQ: VRSN), the leading provider of intelligent infrastructure for the networked world, today announced that One Communications has selected VeriSign to be its premier provider of Signaling System 7 (SS7) and database services for its voice network. By outsourcing its SS7 network to VeriSign, One Communications can more quickly deploy new revenue generating services while realizing the benefits of VeriSign's reliable and scalable infrastructure.

One Communications was formed in July 2006 through the merger of CTC Communications, Conversent and Choice One Communications, creating the largest privately held competitive local exchange carrier (CLEC) in the United States. Choice One had already been a longtime VeriSign customer. The convergence of three separate networks presented One Communications with the challenge of creating a single, efficient network in a cost effective manner.

"Based on our past experience with VeriSign, we were confident that they would be able to help us quickly integrate our SS7 network services -- allowing us to optimize performance and realize the synergies associated with a common platform," said Jim Weidman, vice president of engineering, One Communications. "Their commitment, open communication, and knowledge were assets that contributed to the overall success of the project," he added.

In addition to VeriSign's SS7 network, the company was able to deliver Calling Name, Toll-Free Services and Local Number Portability, helping One Communications to improve overall performance and profitability.

"VeriSign operates the largest independent SS7 network in North America, which we employ to offer our customers a wide selection of innovative database services to meet their diverse needs," said Bill Wolfe, senior vice president, VeriSign Communications Services. "That breadth of technology allowed us to quickly achieve network synergies across each of the three networks One Communications was managing, creating a smooth transition."
