ITXC, which claims to operate the world's largest international VoIP network, has begun using Cisco Systems' new Multiservice IP-to-IP Gateway to provide the demarcation between VoIP networks for media, control, and management. The demarcation is required for the high-volume bilateral exchange of VoIP traffic between carriers. The new Cisco Multiservice IP-to-IP Gateway has enabled ITXC.net to quickly establish over a dozen new direct carrier-class VoIP connections between ITXC's wholesale VoIP network and wholesale and retail carriers worldwide. It provides support for each carrier's independent call accounting and secure settlement, network privacy and routing. ITXC.net is now exchanging approximately 85 million minutes per month with internetworked VoIP carriers, including earlier generation VoIP connections that are currently being upgraded to this new carrier-class model.
Previously, carriers with VoIP networks have generally converted back to circuit-switched for inter-carrier connections. Earlier generation VoIP to VoIP interconnections required case-by-case custom engineering because of equipment vendor and call control differences and also involved an ongoing technical interdependency that limited independent and secure evolution of each individual network.
The companies said that ITXC is also exploring how to use the Cisco Multiservice IP-to-IP Gateway for its ability to enable packet-based interconnection between ITXC.net and the broad installed base of Cisco AVVID enterprise networkshttp://www.cisco.com

- During Q2 2003, ITXC carried a total of 999 million minutes of IP telephony traffic, up from 778 million minutes in the second quarter a year ago and 884 million minutes in Q1 2003. Revenue per minute decreased from 9.2 cents in the first quarter to 8.4 cents in Q2 2003.
