ITXC Corporation (Internet Telephony Exchange Carrier) was a US-based wholesale provider of Voice over IP (VoiP), Internet-based phone calls.
It was co-founded by Tom Evslin and his wife Mary in 1997 with seed money from AT&T and VocalTec (Nasdaq: VOCL). In 2000, it had the largest Internet telephony network in the world. The company was acquired by Teleglobe Bermuda Ltd. in 2004.
The technology to power ITXC's voice over IP network was initially provided by Israeli company VocalTec, who also owned 20% of the company but later sold its stake. In 2003 the company moved to exclusively use Cisco's equipment.
