Business Editors/Hi-Tech Writers

SANTA CLARA, Calif.--(BUSINESS WIRE)--April 4, 2000

During a keynote at the Telecom Business Conference 2000 Conference & Expo here, ITXC Corp(R) (Nasdaq: ITXC) Chairman and CEO, Tom Evslin, announced that ITXC.net(TM), the world's largest Internet telephony network, has now grown to 211 points of presence (PoPs) from 165 at the beginning of 2000.

This means that ITXC can use the Internet to carry phone calls - even calls between ordinary telephones - to and from 200 points in 131 cities in 55 countries on all populated continents. ITXC began commercial wholesale Internet telephony service on April 2, 1998.

"Using the Internet to carry calls to anywhere on the globe is highly subversive to traditional telephone monopolies," says Robert Rosenberg, President of Insight Research Corp., a Parsippany, NJ based telecommunications market research firm. "ITXC.net now has the reach to make a difference in the industry as traffic migrates from the PSTN to the Internet," according to Rosenberg.

Because ITXC uses the public Internet as its infrastructure, it has been able to build a worldwide network many times faster than would have been possible using traditional telephony circuits or even private IP bandwidth. ITXC.net grew from nothing to its current size in exactly two years of commercial service.

According to Evslin, "Speed of deployment is almost as significant an advantage for Internet telephony as cost of transport." ITXC carried over 150 million wholesale minutes during 1999, more than 72 million of these were in the fourth quarter alone when traffic grew sequentially by 70% from the third quarter.

ITXC routes phone-to-phone and web-to-phone traffic over ITXC.net. ITXC controls the quality of Internet calls by using its patent-pending BestValue Routing(TM) technology. Callers using ordinary phones are usually not even aware that their carriers have chosen to route over the Internet through ITXC since they get the quality they expect.

Web callers get the benefit of technology proven by meeting the needs and expectations of phone-to-phone customers.

Ten of the top twelve facilities-based US international carriers have contracted with ITXC to complete international calls for them. Three of the top European carriers are connected to ITXC.net. Eleven PTTs, including China Telecom, Gambia Telecommunications Company, and Korea Telecom, are ITXC affiliates. Announced web-based customers include Dialpad.com, MediaRing, and Onebox.com.
