The US Patent and Trademark Office has issued international carrier ITXC with a patent for a system that is claimed to improve the quality of phone calls placed over the Internet.

"The patent broadly talks about a distributed system that monitors the network constantly with preset criteria to check the network and engage in rerouting," said Ted White, vice-president and general counsel for ITXC, a wholesale carrier of international phone calls.

ITXC is pleased to have the patent in their portfolio and foresees the company using the patent more defensively than offensively. "It is good to have for trading off with partners and for cross-licensing," said White.

The company reports its software tools allow it to assure the quality of a call and even reroute the packets based on the status of gateways they are monitoring on both ends. ITXC said its software permits it to reroute the call even as it is taking place.

White said the patent builds upon the company's BestValue Routing technology, which manages and controls the quality of service over ITXC.net.

ITXC has contracts with all the major US long-distance carriers and with six of the 10 largest carriers in the world.
