Bellevue, Wash. -- Onyx Software (NASDAQ: ONXS) and Ericsson today announced a strategic alliance to bring a powerful customer relationship management (CRM) solution to market that is optimised for wireless, Internet, and call center users. Ericsson Australia recently announced the formation of Customer Conexions - a new business that is helping change the way companies relate to their customers. The key offering of Customer Conexions is a convergence of Ericsson's consulting and systems integration expertise, the flexibility of its wireless access technology and the power of mission-critical CRM technologies.

"We're very excited to be working with Onyx Software. Onyx Front Office and Onyx Enterprise Portal are world class CRM solutions, which when married with Ericsson's wireless data and contact centre capabilities, provide a compelling case for our customers," said Andrew Sherman, marketing and channels manager for Customer Conexions. "'Wireless CRM' is a new and emerging segment of the CRM market and Ericsson and Onyx intend to work closely to help define this exciting opportunity for the benefit of our customers."

"There is tremendous opportunity for companies to embrace an enterprise-wide, customer-centric approach to CRM that embodies the convergence of mobile data services, mobile phones and personal digital assistants such as palm-tops, and the Internet," said Brent Frei, President and CEO of Onyx Software. "Ericsson's expertise in developing and implementing wireless and call center technologies is a perfect complement to our leading Internet CRM technologies. By combining our strengths in Ericsson's Customer Conexions, companies will be able to adopt a truly enterprise-wide customer-centric approach to doing business, giving both the consumer and the vendor the ability to do business anywhere, any time."

Iain Anderson, Program Director for Application Delivery Strategies, META Group, commented on the partnership saying, "This partnership offers broad market opportunities for both Onyx and Ericsson. Onyx Enterprise Portal is very complementary with recent Ericsson announcements regarding mobile Internet capabilities and web customer service offerings. Ericsson will gain a leading fully integrated CRM application suite which will expand its telephony-centric offering across the enterprise, presenting a broader target audience and hence a deeper relationship with its client base."
