Another firm, Internet Technologies , also plans to offer this service by the end of the year, said President Rafal Plutecki. The service would immediately connect a speaker with his party and the voice connection would be seamless -just like talking on the phone, Plutecki said. ATOM's Wichniewicz said he is unsure whether his company's service will require a separate line. Donajski said he has participated in trial runs testing telephone services via the internet with Warsaw University's Interdisciplinary Center for Super Computing and Modeling. His computer phone call to the United States was as clear as a normal domestic phone call, he said.
Internet security is another value-added service offered by providers.
As a growing number of companies use the internet or other public networks for financial transactions or to store sensitive information, they have needed to boost security. A few years ago only a handful of internet connections came with a firewall, or security that blocks hackers from gaining access to a company's computer system through the intemet link, said ATOM's Wichniewicz. That threat prevented many companies from hooking up their systems to the internet. Two basic solutions exist for companies seeking to enhance their internet security. A firm can construct a firewall to limit access to its computer system or use encryption to codify sensitive information.
