SAN JOSE, Calif., June 30, 2006 - Cisco Systems, Inc., (NASDAQ: CSCO) - Cisco Systems® today announced it has completed the acquisition of the privately-held companies Metreos Corp of Austin, Texas, and Audium Corp of New York, New York. Both of these companies offer easy to use, drag and drop, application creation/integration environments which will strengthen Cisco's Service Oriented Network Architecture (SONA). With these acquisitions, Cisco will help enable its ecosystem of development partners to easily create and deploy applications that integrate Cisco's Unified Communications solutions with value-added business applications. The result is more effective communications and streamlined business processes.

In March 2006, Cisco announced its Unified Communications system, based on Cisco's SONA, which enables enterprise customers to integrate their communications systems with their IT infrastructure, thereby creating a single enterprise-wide unified communications platform. The Cisco Unified Communications system of voice, video and IP communications products and applications enables organizations of all sizes to communicate more effectively by leveraging all services located in the network from anywhere, with any device, at anytime.

By acquiring Metreos and Audium and their standards-based creation and integration tools, Cisco can enable customers and partners to rapidly build customized unified communications applications that are fully integrated across the enterprise IT infrastructure, enterprise applications, and enterprise contact centers.

With the close of these transactions, Metreos and Audium products are now integrated into the Voice Technology Group, reporting into Don Proctor, senior vice president.
