Cisco Unified Wireless IP Phone 7921G

Product Overview

Cisco® Unified Communications is a comprehensive IP communications system of voice, video, data, and mobility products and applications. It enables more effective, more secure, and 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 Cisco Unified Communications extends throughout the enterprise with a powerful, converged wireless solution with intelligent wireless infrastructure and an innovative product: the new Cisco Unified Wireless IP Phone 7921G (Figure 1). The device delivers on-campus mobility to users using the voice-over-wireless LAN.
