Business Editors/High-Tech Writers

WESTFORD, Mass.--(BUSINESS WIRE)--May 12, 2003

Concerto Software, Inc. (NASDAQ: CRTO), a proven provider of customer interaction management (CIM) solutions, announced that the newest version of its comprehensive outbound customer contact solution, Unison(R), became generally available on May 9, 2003. Unison Version 7.0 delivers greater system capacity, redundancy and performance for businesses that produce high call-volumes and need to improve campaign effectiveness.

The latest version of Unison supports dual Digital Communications Processors (DCPs) in a single system tied together via ATM (Asynchronous Transfer Mode). This capability doubles the line-to-agent ratio in a given physical system allowing for increased productivity. Support for dual DCPs in a single system also lowers the cost of acquisition and ongoing operation by reducing the number of systems that need to be deployed and maintained.

"In the past year or so, Concerto Software has seen considerable success with its inbound and multichannel strategy, notably through the acquisition of CELLIT and the introduction of EnsemblePro(TM)," said Sheila McGee-Smith, President & Principal Analyst for McGee-Smith Analytics. "However, there is a large portion of Concerto Software's embedded base whose needs are fully met with the Unison outbound solution. The release of 7.0 continues to support these customers by improving and expanding the Unison application."

Unison is Concerto Software's comprehensive outbound customer contact solution. The software is specifically designed for businesses that undertake extensive telemarketing, proactive customer contact, and collections campaigns. Unison contains all of the tools needed for outbound contact, including predictive dialing, call blending, browser-based agent desktop, real-time reporting and campaign development. These tools serve to maximize agent productivity and work to enhance the quality of each interaction.
