Presence and installation of Sonus softswitches at three major telecom "meeting places" permit IP voice traffic and application exchange with the world’s communications carriers

Foster City, Calif., USA, March 21, 2007 -VoEX™ Inc., an IP managed-service provider bridging the gaps between VoIP-carrying networks, announced that it has extended and equipped its managed VoIP network to meet global voice carriers at three of the world’s largest interconnection hubs:60 Hudson in New York, Equinix in Chicago, and Telehouse in London.Connections made at these three "SuperPOPs"(points of presence) give VoEX’s peering customers and partners core IP access to tens of millions of wireless and wireline, VoIP- and TDM-based telephony end points.

At these three carrier-neutral meeting facilities, VoEX has the flexibility and security to seamlessly exchange VoIP traffic and applications with bandwidth providers from all over the world.It currently maintains such relationships with BT Wholesale, Level3, Telia Sonera, Deutsche Telecom, France Telecom, Global Crossing, MCI Worldcom and many others.

This interconnection capability enables all VoEX partner and customer networks to route their voice traffic across continents and national borders without interrupting the IP session, and to carry as many calls as possible, as far as possible over IP, saving money on inter-network PSTN hops and long termination legs.On calls made between IP endpoints, it preserves support for such IP-dependent applications as calendaring, presence, collaboration and multiplayer gaming. Where originating and/or terminating endpoints are TDM-based, VoEX also leverages its own and partners’ gateways to transport those calls through the VoEX network.

Interconnection also gives worldwide participating carriers the opportunity to map their subscribers’ phone numbers to IP addressed endpoints using VoEX’s growing ENUM-based SuperRegistry™ service offering.This makes it possible for them to route calls via the VoEX VoIP network to a growing percentage of the world’s wireless and wireline, TDM and IP phone numbers, at prices below local tandem rates.VoEX has newly equipped these POPs with network switching solutions from Sonus Networks.These perform any-to-any transcoding between protocols and act as gateways between TDM and IP; they also query the VoEX SuperRegistry database to route calls along the most cost-effective path.The Sonus switches scale up to extremely large configurations, while sustaining 99.9999 percent availability and carrier-grade voice quality.

VoEX’s presence at London Telehouse permits peering with most European communications carriers. The Equinix site specializes in links to Asian carriers Smaller VoEX POPs in North American cities, as well as those of peering carriers in the U.S. and elsewhere, take traffic from these SuperPOPS downstream to smaller markets throughout their territories.They terminate or originate calls to or from their own gateways, or from the IP-addressable network borders of their VoIP-enabled subscribers. For multinational enterprises, the VoEX global reach also presents the opportunity to avoid PSTN hops and charges between far-flung regional offices.Using their own internal directories and IP PBXs, such companies can simply use VoEX to provide the trunks and reconcile the signaling and codec differences between locations.
