Calltrade Chooses Telarix's iXTools(TM) to Manage Their Entire Interconnect Business.

VIENNA, Va. -- Telarix, Inc., the leading provider of Interconnect Business Optimization (IBO) and settlement solutions for content providers, IP service providers and global fixed and mobile operators, today announced that Calltrade Carrier Services AG has selected its entire iXTools suite to optimize its growing global interconnect business. Calltrade will deploy Telarix's complete portfolio of business optimization solutions which includes replacing a competitive interconnect billing system with Telarix's next generation interconnect billing solution, iXBill[TM].

As part of Telarix's comprehensive portfolio of partner management, routing optimization, and revenue assurance solutions, iXBill offers a robust and highly flexible interconnect billing system that allows carriers to eliminate revenue leakage by supporting interconnect agreements with other carriers, regardless of the level of complexity and the type of network.

Unlike many of the billing-only focused interconnect solutions available in the market today, iXBill provides embedded revenue assurance capabilities, leveraging its integration with other key carrier business functions including agreement management; route optimization; pricing; and audit and reconciliation. This level of sophistication ensures that all billable activities are accurately captured, rated and billed while allowing service providers to support a variety of agreement types and rating scenarios including the multi-party settlements and sophisticated revenue sharing partnerships common in today's dynamic voice, data, and IP interconnect market.

"In this competitive marketplace, delivering next generation interconnect optimization solutions to a sophisticated service provider like Calltrade requires a partner staffed by subject matter experts with extensive knowledge and experience in routing optimization, interconnect management and revenue assurance," said Daniel Groth, CEO of Calltrade. "Telarix was the only interconnect business optimization and settlement solution provider which had the unique combination of technology, vision, and expertise required to meet the specific business needs of our growing wholesale business."

"We are excited to be working with Calltrade, a service provider with a reputation for innovation and success," said Don Lynch, CEO of Telarix. "By deploying Telarix's pioneering interconnect optimization solutions, Calltrade has all the essential ingredients required to grow and expand its wholesale business."

Telarix's iXTools is a powerful suite of software modules that enables carriers to reduce costs and increase profitability across their interconnect networks. By analyzing both revenue and cost information associated with telecom traffic in near real-time, carriers can optimize network routing and identify financial risks and opportunities while ensuring that every call is captured, rated and billed accurately. Three of the world's five largest telecom providers depend on iXTools to optimize their interconnect business.

The Yankee Group named Telarix as one of the only interconnect solutions providers to address the four critical value areas for service providers: Route Optimization; Pricing and Margin Management; Billing; and Verification, Audit and Reconciliation.
