VOEX is a company I've been hearing a lot about lately. I haven't had a chance to talkw ith them directly yet, but I'll be working on that shortly. We'll be hearing more and more about the.

VOEX’S SuperRegistry™ REACHES OVER 250 MILLION PHONE NUMBERS
VoEX’s SuperRegistry Carrier ENUM Database, Peering Infrastructure and IP Trunking Move Voice Carriers Closer to End-to-End IP

Foster City, Calif., March 20, 2007 - VoEX™ Inc., an IP managed-service provider bridging the gaps between TDM and VoIP-carrying networks, has announced that its SuperRegistry™ has reached over 250 million IP-addressable phone numbers, the largest such registry of any wholesale or retail VoIP carrier in North America.

VoEX has built a pure VoIP peering infrastructure using its network resources and its SuperRegistry™, an advanced carrier-grade ENUM database that maps telephone numbers to IP destinations. With this, it delivers any-to-any connectivity, from VoIP to PSTN users and vice versa. The SuperRegistry peering solution also supports the development of advanced IP-based applications – including enhanced directory, mobility, location and presence services -- that can bridge the voice and data service worlds. As the leader in the peering, registry, and IP/TDM interconnect space, VoEX is in a unique position to lower costs, converge IP and TDM voice traffic, and provide advanced applications to end users.

Circumventing PSTN tandem rates between VoIP carriers
Carriers and service providers who have registered their network entry points on VoEX’s ENUM-based SuperRegistry gain managed IP access, through VoEX, to each others’ endpoints. They can terminate traffic – TDM, IP, and hybrid combinations of both -- for each other at costs below local tandem rates. They can also enjoy the incremental benefit of global VoIP reach while avoiding any capital expenditure and eliminating some PSTN database query charges.

VoEX’s customer base includes wireless and wireline carriers, MSOs, cable operators, VoIP service providers, large enterprises, universities, and e-communities like Yahoo and LinkedIn. The SuperRegistry currently includes a significant amount of North America’s wireless telephone numbers, and is expected to reach additional wireless phone numbers and a majority of wireline numbers by the end of 2007.

How SuperRegistry Works: Peering Example
In a sample VoEX call flow, when Sidney dials Bradley on a traditional PSTN line, the call is routed to the nearest bridging gateway, whether owned by VoEX’s carrier customer or supplied and remotely managed by VoEX. The gateway converts both voice media and signaling into SIP packets before forwarding the call into VoEX’s network. Querying its SuperRegistry ENUM database, VoEX finds the IP address of Bradley’s network entry point or gateway and routes the call there. If his phone is IP-based, Bradley’s IP network then consults its own database to complete the call. If not, the call is forwarded to the gateway that serves his TDM phone.

In an IP-to-IP call, this lookup and routing not only avoids PSTN transport entirely, it routes calls independently of the routing tables and SS7 signaling used by traditional telcos.

Records of all phone numbers and their associated network entry points are stored in VoEX’s registry. To keep this information current, all additions and changes are regularly distributed throughout the VoEX network by its internal peering grid. Peers can thus connect through VoEX, which can transcode the industry’s widest range of signaling protocols (SIP, H.323, MGCP) and codecs.

The VoEX Peering Triple Play
Established in 2002, VoEX uniquely combines its dynamic address registry with a robust transport network and a global, peering infrastructure of media and signaling gateways, routers, softswitches, session border controllers, and other network elements.

Taken together, this combination saves VoEX’s customers money by allowing them to carry as many calls as possible, as far as possible, over IP. They save call setup times and transport costs otherwise spent on PSTN-based bridging hops between IP networks. They benefit from VoEX’s intelligent, least-cost routing and carrier-grade voice quality and reliability. When end points are TDM-based, customers save on termination fees; long PSTN-based termination legs are shortened by using the IP off-ramp (gateway) closest to the called device.

VoEX’s managed services proposition offers a no-capex entry into IP-to-IP calling. Its registry of phone numbers, continually updated with local number portability feeds and grown with additional peers, provides over one million routes for off-net interconnection, chosen with least-cost or best-quality priorities.

VoEX’s proprietary any-to-any interconnectivity technology bolts onto customers’ existing infrastructure of SS7/C7 signaling, ISDN, and such non-standard VoIP devices as Asterisk and SER servers.

In the longer term, end-to-end VoIP connectivity opens the door to applications and services that PSTN transport hops cannot support. These might include rich content, collaboration and presence-based communications applications, push-to-talk, gaming, video, and media services yet to come. The multi-channel capability of ENUM also has the potential for registering multiple endpoints and subscriber preferences under one registration record, providing a path for emails, text messages and faxes as well as voice calls to any of several devices.

In launching and growing its SuperRegistry, VoEX enjoys the be top-tier customers include Qwest, Global Crossing, VoiceOne, USA Datanet, Point One, Grande Communications, Broadwing(Level3), Merit Network, Interactive Intelligence, Talk America, Transcom, Internet2, University of Michigan, Northwestern University, and Georgetown University. By purchasing from VoEX, these customers gain the capacity to deploy VoIP, reduced operating costs, faster time-to-market and greater profitability.
