MELVILLE, NY – October 15, 2008 – Centennial, a leading mobile and broadband provider in Puerto Rico, has selected CosmoCom (www.cosmocom.com), the leader in Contact Center Consolidation 2.0, to help it sustain the high levels of customer service that differentiate the carrier in its markets. In Puerto Rico, the company has over 427,000 wireless subscribers, plus more than half a million broadband access lines. Centennial's selection was the outcome of a systematic and thorough evaluation process. The initial rollout will be for the 400 agent positions in Centennial's contact center for wireless and wireline customer account, billing and technical support.

Centennial was impressed by CCU's very large capacity, its seamless handling of multiple sites, its ability to interoperate with its BroadSoft IP Centrex platform, and its open APIs supporting fast integration with the carrier's other systems. Centennial also noted CCU's multi-tenant architecture, which will enable the company to use the platform both for its internal contact center needs and to provide a contact center on-demand (CCOD) service to its customers. Centennial's 2,000 business customers with more than 20,000 Centrex lines will be the initial target for the CCOD offering.

"Centennial has a proven local market strategy built on four pillars: a great network, enhanced retail presence, highly-trained associates and a strong brand," said Gustavo Maurizo, CIO Centennial of Puerto Rico. "CosmoCom's platform strengthens each of these pillars by enhancing the reachability of our contact center agents and the knowledge of all the workers who play a role in the customer satisfaction process".

"Centennial is a wonderful example of a customer that can benefit from our Win Twice value proposition to telephone companies," said Ari Sonesh, Chairman and CEO of CosmoCom. "Our platform can grow with the company to provide not only first rate customer support as its user base grows, but also a source of new revenue from offering contact center as a hosted service."
