NexTone Multiprotocol Session Controller Deployed In ITXC.net

NexTone Communications announced that ITXC Corp. has deployed the Multiprotocol Session Controller in the company’s global VoIP network, ITXC.net.The NexTone Multiprotocol Session Controller enables ITXC for the first time to extend its global service with robust and scalable interconnection to virtually any SIP- or H.323-based VoIP network.

The NexTone solution enables secure and flexible interconnection between VoIP networks regardless of network’s call control protocol, equipment vendor, or internal architecture. ITXC.net interconnects more than 175 countries via direct traffic relationships with hundreds of national and global carriers using IP gateways that transmit millions of minutes daily, and now can interconnect with higher capability and lower costs to a more diverse range of VoIP-based carriers.

The Multiprotocol Session Controller on the border of ITXC.net serves as an intermediary to affiliate VoIP networks, providing dynamic call-admission control, SIP/H.323 signaling interworking and network address translation (NAT) capabilities. The NexTone solution also eliminates many of the T.38 fax interoperability issues that are common among different equipment vendors’ VoIP gateways. These VoIP interconnection capabilities enable ITXC to interconnect to a diverse range of local VoIP carriers directly across the Internet backbone, without requiring or creating technical dependencies between ITXC.net and its peer networks.

"NexTone session controllers allow us to establish a robust IP border between our Cisco-based network and other peer VoIP networks based on almost any other vendor or protocol," said John Landau, executive vice president of product management at ITXC. "We believe NexTone's Multiprotocol Session Controller will be an important element in our push to make VoIP interconnects as seamless and vendor-neutral as SS7 and TDM interconnections between peer circuit-switched networks are today. Without this robust border, peer VoIP networks are difficult to interconnect and may painfully impede each other's ability to independently evolve - a real challenge for a carrier's carrier like ITXC which exchanges millions of minutes per day with hundreds of local carriers around the globe. The MSC on the border of ITXC.net is a clean solution for delivering interconnect flexibility, security and scalability specifically fitted to each of our VoIP carrier affiliates. With the NexTone solution, ITXC.net serves as a 'universal adaptor', exchanging traffic amongst many otherwise incompatible VoIP-based carriers and also hundreds of classic circuit-switched carriers."

“Business Sviaz Holdings is a VoIP-based carrier in the very competitive Russian market. We are impressed with the robustness, scalability, and low cost of our NexTone-based network interface to ITXC.net,” said Victor Belov, business development director of BSH. “Since we started exchanging international traffic with ITXC over the internet backbone in May 2003, we have experienced high quality and reliability, and look forward to continued rapid traffic growth.”

Added Raj Sharma, co-founder and president of NexTone, “ITXC’s deployment of our solution further demonstrates that NexTone is the leader in carrier-class session controllers delivering the high level of VoIP scalability, redundancy and interoperability that a Tier 1 provider requires. The Multiprotocol Session Controller provides a secure, cost-effective demarcation point between ITXC and its partners, while also insulating the core network from peering complexities such as signaling interoperability. In this way, our solution helps ITXC simplify its core network by standardizing on Cisco solutions and enabling VoIP connectivity with disparate partner networks.”
