Major US Carrier Selects Evolving Systems for VoIP Number Management

ENGLEWOOD, CO--(Marketwire - March 9, 2011) - Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of software solutions and services to the wireless, wireline and IP carrier market, today announced that a major US carrier has selected the Company's number resource management solution, NumeriTrack®, to replace its current legacy system.

With demand for VoIP services on the rise and the carrier's plans for growth in this market, the carrier was concerned about its current system's ability to scale, not just in capacity but flexibility. As a result, the carrier sought a new, more flexible solution to support its existing subscriber base and future growth.

Evolving Systems' NumeriTrack solution will provide the carrier with an open, scalable, centralized system allowing the carrier to store, assign, track and manage all their VoIP number inventory.

"We have seen an increasing demand for our NumeriTrack solution over the past 12 months," says Thad Dupper, CEO and chairman at Evolving Systems. "This order further demonstrates how scalable and flexible the solution is at managing a carrier's entire number inventory -- wireline, wireless and VoIP numbers -- for both current and future requirements."
