ENGLEWOOD, CO--(Marketwire - December 13, 2007) - Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and IP carrier market, today announced that one of its European customers has placed an order to deploy the NumeriTrack resource management solution to support the rollout of their wireline network.

Launching a wireline network is a complex undertaking, requiring a carrier to find a solution that meets both tactical and strategic requirements. A new resource management solution has to be able to support the network launch in rapid timescales as well as provide a seamless transition from the current solution. After a detailed evaluation, the customer selected Evolving Systems' solution as the best fit for meeting these requirements.

In order to support this launch, Evolving Systems' current Tertio™ solution will be expanded to support wireline and convergent services in addition to the wireless services it already supports. The NumeriTrack resource management solution will be integrated with Tertio and support the identifiers associated with wireline services, including telephone numbers and email addresses.

"We are very pleased to announce this order for our international version of our NumeriTrack product," said Thad Dupper, president and CEO of Evolving Systems. "Our NumeriTrack product, which has been very successful in the North American markets, is now available to support international numbering plans and we are seeing strong interest from carriers in every region. This order was placed by one of our Tertio customers, demonstrating that we have earned this customer's confidence and continue to meet our customers' expectations."
