LONDON – March 14, 2006. LignUp Corporation, a leading provider of converged communications solutions, today announced that TeliaSonera International Carrier (TSIC), a leading global provider of cross-border communications services, will deliver FastLign managed IP telephony services to service provider customers across Europe. An alliance founded by LignUp, NexTone Communications and other industry leaders, FastLign is working to accelerate the adoption of IP telephony services by providing a managed services platform that allows service providers to rapidly and cost-effectively deliver competitive hosted services. TeliaSonera International Carrier will offer the FastLign services offering to its global customer base, which includes Internet service providers.

“In the past, IP telephony services have been prohibitively time consuming and expensive to build, deploy and manage,” said Johan Andersson, VP and head of Marketing, Strategy and New Busness at TeliaSonera International Carrier. “Service providers must build these services from the ground up, integrating a wide variety of technologies and services to provide a complete services solution. FastLign provides service providers with a hosted telephony services model that removes system integration cycles, provides operations support and allows customers to address the needs of the marketplace.”

By providing the advantages of a fully managed and supported wholesale service, the FastLign alliance reduces deployment timetables and upfront and ongoing operating costs for hosted telephony service providers. In Europe, IP telephony service provider Streamdoor Ltd. will host the completely integrated FastLign services architecture and provide full datacenter capacity, system support and help desk capabilities, while providing access to the proven, world-class TeliaSonera International Carrier global IP network. In this way, FastLign and TeliaSonera International Carrier will reduce a service provider’s “time-to-market” from several months to a matter of days.

While delivering the benefits of a fully managed service, FastLign also allows customer service providers to differentiate themselves in the marketplace. FastLign service provider customers license solutions directly from FastLign Alliance member companies. This licensing model enables them to fully modify and customize their services to address the specific needs of their customers. Providers can speed their service offerings to market by easily modifying and deploying a variety of turnkey applications from LignUp and other FastLign partners. Furthermore, LignUp’s flexible platform for innovation allows the easy development of unique hosted voice applications that further differentiate service providers.

“Wholesale managed services have been with us for years, but they are limited in that they provide lowest common denominator capabilities,” said Kevin Nethercott, founder, president and COO at LignUp Corporation. “Service providers building services on these traditional services are severely limited in how well they can innovate and differentiate their service features and capabilities. Because this is a competitive marketplace and shows no sign of becoming any less competitive, the inability to differentiate can destroy your business. LignUp is pleased to work with TeliaSonera International Carrier and our FastLign partners to provide service providers a robust managed services offering and the flexible development platform they need to stay ahead of the competition and sustain their businesses far into the future.”
