Business Editors

WESTFORD, Mass.--(BUSINESS WIRE)--Dec. 18, 2003

Concerto Software's Globalized, Unified CIM Solution Honored for

Vision and Innovation

Concerto Software, Inc. (NASDAQ: CRTO), a proven provider of customer interaction management (CIM) solutions, today announced that Technology Marketing Corporation's (TMC) Customer Inter@ction Solutions magazine recognized Concerto Software's EnsemblePro(TM) unified CIM solution, as "Product of the Year." This marks the second straight year that Concerto Software(TM) solutions have earned a Product of the Year distinction from Customer Inter@ction Solutions, the premier publication in the CRM, call center and teleservices industry.

EnsemblePro is a complete, globalized multi-channel CIM solution that brings a powerful superset of the best functionality from all of the Concerto Software products together in a single unified platform. Designed from the ground up to incorporate the broad multimedia functionality required by today's contact centers - including ACD, predictive dialing, IVR, email, Web chat and collaboration, universal queuing, recording and reporting - EnsemblePro also offers the ability to connect with and add value to existing contact center point solutions. Available in English and seven additional languages (Traditional Chinese, Simplified Chinese, Japanese, French, German, Korean and Spanish), it has become much easier for non-English speaking countries to utilize the solution, resulting in more efficient, effective contact center operations and enhanced customer service.

"Concerto Software's EnsemblePro solution is a clear leader in the CIM sector. We're proud to reward their hard work and innovation with a Product of the Year Award for 2003," said Nadji Tehrani, chairman of TMC and founder of Customer Inter@ction Solutions magazine.

"Concerto Software is delighted to be recognized by a group as prestigious as TMC for our innovation and vision in bringing a globalized, unified CIM solution to the contact center market," said Ralph Breslauer, executive vice president for sales and marketing at Concerto Software. "Companies around the world look to EnsemblePro for its industry-leading inbound and outbound customer interaction capabilities. This award validates our success in delivering EnsemblePro to truly help businesses reduce the complexity in their contact centers."

According to Customer Inter@ction Solutions' group editor-in-chief, Rich Tehrani, EnsemblePro was selected because it demonstrates true innovation, which is the hallmark of Product of the Year winners. "The Product of the Year award is meant not only to honor the outstanding teams who developed and manufactured the products on our winning list, but also to educate our readers on the vast array of offerings in this market. Choosing the winners was a difficult process, and the editorial team spent many hours studying the applications they received from vendors, as well as looking through materials we collected on our own over the past year." A full list of Product of the Year winners will appear in the January 2004 issue of Customer Inter@ction Solutions magazine.
