Avaya and Onyx Software Introduce New Software Connector Created By SimpliCTI
Connector To Provide Integration Between Avaya and Onyx Products

Las Vegas - Today at the Call Center & CRM 2003 Las Vegas tradeshow, Onyx Software (NASDAQ: ONXS), Avaya (NYSE: AV) and SimpliCTI Software Solutions Inc. announced the immediate general availability of a new software connector, which will integrate contact center interactions between Avaya Interaction Center (IC) software for multi-media customer care and Onyx Employee Portal (OEP).

The IC/OEP connector provides each contact center agent access to a customer's detailed information in the Onyx database as soon as the customer calls. This enables the agent to provide real-time, personalized and focused service based on the information at their fingertips. Customers spend less time waiting for agents to retrieve information, and instead, receive immediate processing of their requests.

Using the connector enables simpler implementation of sophisticated CRM applications and allows companies to focus on the applications, not the connection, reducing implementation efforts and speeding time to return-on-investment. Companies who take advantage of the connector can also reduce the level of integration services, which lowers the total cost of ownership and mitigates the risks of implementation.

The SimpliCTI-developed software connector delivers out-of-the-box integration and enables pre-established communication between the Avaya and Onyx products. The connector shares information between the two systems and provides bi-directional messaging and function calls.

"This connector can minimize cost and customization efforts associated with bringing Avaya and Onyx together," said Anna Dorcey, director of the Avaya DeveloperConnection Program. "Our customers count on us for reliable, secure networks that enhance customer relationships, and this is an example of how we work with our DevConnect members to deliver these targeted business solutions."

"SimpliCTI's products are designed to provide solutions that decrease costs, increase revenue, and improve customer satisfaction," said Bruce Calhoon, president and COO at SimpliCTI. "Companies seeking a comprehensive contact center solution can now avoid the near-term costs associated with custom coding this communication link needed to integrate Avaya and Onyx."

"In the contact center arena, success is all about driving cost down, increasing customer value and improving the quality of customer service," said Mark Longton, Alliances Manager at Onyx Software. "Connecting Onyx and Avaya with the SimpliCTI connector enables an exemplary level of customer service that is the hallmark of world-class companies."
