PRINCETON, N.J.--(BUSINESS WIRE)--Aug. 9, 2001

ITXC Corp (Nasdaq:ITXC) today announced that Theodore Weitz has joined ITXC as VP, General Counsel.

Mr. Weitz has 23 years of legal counsel experience in the communications and technology industries with companies including Tachion Networks, Inc., Intel Corporation, Dialogic Corporation, Lucent Technologies Inc., and AT&T Corp.

At these previous companies and now with ITXC, Mr. Weitz is responsible for global legal activities such as contracts and transactions, employment, securities, mergers and acquisitions, intellectual property, and litigation.

"Ted is well-respected in the communications and technology industries for his legal knowledge and business acumen," said Tom Evslin, chairman and CEO of ITXC. "His expertise is already benefiting ITXC as we continue our rapid expansion in the global telecom market."

Over the last four years, ITXC has built the world's largest network for routing calls over the Internet. Originally, most of these calls were placed from the US and Western Europe to people in developing nations.

As telecom markets around the world open to competition, more and more calls are being placed in countries that had previously only received calls from ITXC. Two-way global traffic over ITXC.net(SM) increases volume on ITXC's network, increases revenues for terminating carriers, and provides more competitive rates to ITXC carrier customers.

Putting together solid, innovative legal agreements is important in establishing these new traffic patterns which take advantage of new technology.

Today ITXC.net transports calls to more than 117 countries and provides quality that is equal to and, in some parts of the world, better than that provided by the legacy phone network.

About ITXC:

ITXC Corp (NASDAQ:ITXC) established and operates ITXC.net(SM), the largest global network for voice over the Internet with 559 points of presence in more than 318 cities and 117 countries, as of June 30, 2001. The company is the leading provider of worldwide Internet voice services with more than 2 billion minutes of use since the inception of ITXC.net in 1998.

ITXC's patented BestValue Routing(TM) technology provides such high voice quality over the Internet that tier one carriers use ITXC for worldwide phone-to-phone traffic without indicating that the calls are actually going over the Internet.

Customers include major traditional carriers and RBOCs who achieve lower costs for phone-to-phone calls while maintaining carrier quality, Web merchants who increase sales with ITXC Push to Talk(SM) buttons on Web sites and e-mail, as well as Internet-based Web-to-phone providers and voice portals.
