Arbinet Enhances its Wholesale Carrier Service Interface

New Brunswick, NJ, USA – October 1, 2009– Arbinet Corporation. [Nasdaq: ARBX], formerly Arbinet-thexchange, a leading wholesale telecommunications service provider that offers three ways for carriers and service providers to originate and terminate international voice traffic, has introduced new tools into its network that significantly enhance its ability to support customers and suppliers in a traditional wholesale fashion. Arbinet’s voice termination and origination options also include Private Exchange^SM, an easy, low-risk outsourcing approach, and thexchange™, the industry’s leading Exchange marketplace for buying and selling voice communications. 

Arbinet Carriers Services has no fees and features a single invoice. New tools include a Code Analysis Tool that enables Arbinet to use supplier codes in its wholesale routing plans; a Routing Table Development Tool that utilizes sophisticated blending algorithms to enable Arbinet to generate Routing Tables based on specific quality and pricing requirements; and an integrated Quoting System that enables Arbinet to easily quote rates and buy supply from Carrier Service customers and suppliers.

“Arbinet is an important partner for our wholesale voice business,” said Jochen Mogalle, VP Wholesale at Telefónica O2 Germany. “With Arbinet’s technology, knowledge of the European Telecom market and its ability to terminate traffic to global carriers, Arbinet has helped Telefónica to realize efficiencies in routing portions of our international voice traffic. Arbinet also played a role in Telefónica success in increasing voice quality, stability and consistency in its service for its retail customers.”

“Arbinet is an important and strategic partner for our voice termination business,” said Evgeny Sekeryn, Carrier Business and Sales Director at Russian largest international carrier Rostelecom.  “With Arbinet’s proven technology, knowledge of the international telecom market and its ability to terminate traffic to an extensive list of leading and emerging global carriers, Arbinet provided Rostelecom with aggressive pricing, quality control and efficient routing solution for international voice traffic.  The Rostelecom team is optimistic to work with a partner that invests in technology in order to simplify, improve and solve interconnectivity issues. We are sure that their continued investment in new tools and capabilities will continue to help carriers to meet business goals.”   

“Arbinet is well-known for its highly automated exchange marketplace that seamlessly manages voice traffic flows between buyers and sellers,” said Dan Powdermaker, Senior Vice President of Sales and Marketing for Arbinet. “We launched Carrier Services earlier this year to support those suppliers and customers that seek a traditional wholesale way of working. We offer standard contracts, no fees, multiple routing tables and rate lock. Carrier Services suppliers can reach members of Arbinet’s thexchange and thexchange suppliers can qualify for inclusion in Carrier Services tables. The new Carrier Services tools that we have developed and deployed will help us to more seamlessly and better serve our customer and supplier base.”
