Internet Telephony Project Expected to Increase Teledensity and

Rural Coverage in Gambia

ITXC Corp(R) (NASDAQ:ITXC) and Gambia Telecommunications Company (GamTel), the dominant carrier in Gambia, have signed an agreement to exchange international Internet telephony traffic between the rest of the world and the African nation.

GamTel is the first African carrier to join ITXC's initiative announced earlier this week in Ghana under which ITXC provides technical help in establishing not only international but also domestic Internet telephony to meet the needs of users calling phone-to- phone. Use of IP technology over Gambia's excellent domestic fiber network is expected to accelerate the increase in teledensity, which the carrier is committed to, and penetration of basic phone service to rural areas.

"As we add access lines to meet the needs of Gambians, increased trunk capacity to carry added calls becomes critical," said Adama Deen, Deputy Managing Director of GamTel. "Working with ITXC helps us achieve our goal of better communication both within Gambia and between Gambia and the rest of the world. Using IP technology to carry both calls and data on our existing fiber backbone gives us the advantage of concentrating traffic on one large network linked to the rest of the world by the Internet. Building one network instead of two makes our capital go much further."

According to ITXC Chairman and CEO Tom Evslin, "Gamtel is the eleventh national carrier to connect to ITXC.net; but they are the first to fully embrace Internet telephony as a key tool for a massive increase in domestic capacity as well as international. Gambia may become the world's first fully converged nation with enormous economic benefits."

At the African Telecom Summit in Accra, Ghana, ITXC made an offer to help African service providers with "intellectual capital" to build domestic Internet telephony networks with links to ITXC.net for international traffic exchange. The agreement with GamTel was closed by the companies at the Summit in Accra. Deployment of initial stages for international calling is expected to begin immediately.
