European Customer Selects Evolving Systems' NumeriTrack(R) Solution for Centralized Number Management


ENGLEWOOD, CO--(Marketwire - September 9, 2009) - Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and cable markets, today announced one of its European customers has selected the Company's resource management solution, NumeriTrack®, to replace an incumbent legacy system.

The legacy system has become increasingly inflexible and expensive to maintain over time as business and regulatory requirements have grown. Replacing the system with Evolving Systems' NumeriTrack solution will allow the customer to enjoy the business benefits of superior resource management on a cost-effective computing platform. NumeriTrack provides an open, centralized number management system with the flexibility and scalability necessary to enable the carrier to store, assign, track and manage its entire mobile number inventory.

"This European carrier is looking to use Evolving Systems' NumeriTrack solution to better manage their number-related inventory and to ensure that they also have numbers available to meet their customers' demand, which in this environment is becoming increasingly difficult to predict," said Thad Dupper, President and CEO of Evolving Systems. "From a market perspective, we continue to see strong interest in our international NumeriTrack solution, with this being our third new contract in 2009."
