Cisco® Unified Communications is a comprehensive IP communications system of voice, video, data, and mobility products and applications. It enables more effective, more secure, more personal communications that directly affect both sales and profitability. It brings people together by enabling a new way of communicating in which your business moves with you, security is everywhere, and information is always available - whenever and wherever it is needed. Cisco Unified Communications is part of an integrated solution that includes network infrastructure, security, mobility, network management products, lifecycle services, flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.

The power of the Cisco Unified Communications Family of products extends throughout the enterprise, delivering a powerful, converged wireless solution with intelligent wireless infrastructure and an innovative new product: the Cisco Unified Wireless IP Phone 7926G (Figure 1). This device now introduces two-dimensional (2D) bar-code scanning capability to the successful Cisco Unified Wireless IP Phone portfolio.
