Sonus Networks, Inc., a leading supplier of service provider Voice over IP (VoIP) infrastructure solutions, announced that Telio, the largest and fastest growing access independent VoIP provider in Europe, has selected Sonus' industry-leading IP Multimedia Subsystem (IMS)-ready solutions as the foundation for its next generation IP-based voice network. Telio, which offers primary line residential services throughout Europe, selected Sonus because of its ability to meet European-specific signaling requirements and to support carrier-grade reliability and scalability for Telio's plug-and-play IP-based voice service, which currently carries more than 100 million minutes of voice traffic per month.

"To encourage the adoption of IP-based voice services, it is imperative that consumers experience the same quality, reliability, and ease of use that they're accustomed to with legacy voice offerings," said Alan Duric, co-founder and CTO, Telio. "Telio's service is a straightforward plug-and-play solution. By selecting Sonus as the foundation for the network, we're able to deliver the level of service that our customers expect, introduce interesting new features and applications, and scale as the demand for our service continues to grow across Europe."

Telio offers IP-based voice service in Norway under the Telio brand, as well as offering its Telio Voice Production System (TVPS) service on a white label basis for European ISPs. Telio has deployed a suite of Sonus solutions including the GSX9000 and GSX4000 Open Service Switches, PSX Call Routing Server, SGX Signaling Gateway, and the Sonus Network Border Switch for enhanced security and direct IP-to-IP peering. With a full suite of IMS-ready solutions in place, Telio's network can scale seamlessly, introducing new applications and features quickly and efficiently.

"Sonus is one of the only solutions available today that delivers proven quality and reliability with a robust suite of residential voice features required for primary line service in Europe," said Hassan Ahmed, chairman and CEO. "Sonus is dedicated to helping European operators unlock the potential of next-generation communications, increasing their average revenue per user, and supporting enhanced applications that will redefine the expectations for communications services."

"The European market for both next generation networks and IMS represents one of the most dynamic and rapidly evolving opportunities for vendors in these market segments. Whereas regulatory restraints hampered deployment of solutions throughout the 1990s and early 2000s, the new regulatory paradigm has opened the doors for innovative companies to gain mind- and market share," said Tom Valovic, Program Director for VoIP Infrastructure at IDC. "Sonus, which has been addressing the European market and aligning and customizing resources to meet its unique demands, is well positioned to capitalize on these trends."

Sonus' IMS-ready architecture provides one of the industry's most complete end-to-end network solutions that meet the unique demands of the European market. Sonus' solutions support the delivery of services that match, and in many cases surpass, those services offered through traditional voice networks.

"By providing the sophisticated network foundation needed to support a feature-rich primary line voice service, Sonus is helping to reshape the competitive landscape throughout the European market," said Joop Van Aard, vice president of sales, EMEA, Sonus Networks. "Service providers like Telio are taking advantage of next generation solutions to not only emulate the services available through traditional voice networks, but also to offer new and exciting services that capture consumers' attention, promote customer loyalty, and improve long term customer retention."
