In addition to these 51 locations where ITXC has local IP termination, ITXC can complete calls to every phone in the world through a combination of Internet telephony and traditional PSTN. If there is no ITXC-certified gateway in a destination city, WWeXchange Service completes the call from the US to the destination city using traditional long distance.

ITXC's buying power and experience allow it to obtain this international long distance at much lower rates than most ITSPs would be able to achieve on their own. Moreover, since outbound calling rates from the U.S. are the cheapest in the world, international callers achieve significant savings by having their calls routed through the Internet to the U.S. and from there to other international destinations.

The best savings are achieved when calls can be made all the way to the destination city on the Internet.

ITXC Corp sells its WWeXchange Service to Affiliates in all of the above countries. WWeXchange provides, authorization/authentication, intelligent routing and settlement services so that the Affiliate can enter the market immediately and does not need to have bilateral arrangements with companies all over the world.

The Affiliate has one relationship with ITXC Corp which handles all of those details for them.

ITXC will be adding additional sites every month through 1998 as well as additional capacity at existing sites. ITXC projects that it will have over 75 international gateway sites in its network by the end of 1998. The company currently supports gateways from VocalTec and Lucent.

Each site offering termination must pass ITXC Certification for quality and is monitored by a 7x24 Network Operations Center (NOC) to assure that quality is maintained.
