    Cisco® Unified Communications Solutions enable collaboration so that organizations can quickly adapt to market changes while increasing productivity, improving competitive advantage through speed and innovation, and delivering a rich-media experience across any workspace, securely and with optimal quality

    Product Overview

    The Cisco® Unified IP Phone 6921 is an innovative endpoint that delivers affordable, business-grade voice communications and support for video communications services to customers worldwide.

    The Cisco Unified IP Phone 6921 supports two lines and offers a full-duplex speakerphone for a more productive, more flexible, and easier-to-use endpoint experience. The Cisco Unified IP Phone 6921 supports multi-call per-line appearance, offering end user the opportunity to handle multiple calls per directory number (DN). Fixed keys for hold, transfer, and conference; tri-color LED line and feature keys also make the phone simpler and easier to use.

    The Cisco Unified IP Phone 6921 offers greater personalization, with the choice of two colors and two handset style options. Right-to-left language presentation is also supported on the displays, addressing the language localization needs of global customers.

    The Cisco Unified IP Phone 6921 is also more energy-efficient and eco-friendly, in support of customer green initiatives. A Deep-Sleep option provides energy savings. With this option, the Cisco Unified IP Phone 6921 consumes up to 50 percent less power in off-hours versus when the phone is idle during normal business hours. In addition, reground and recyclable plastics deliver a more earth-responsible solution.

    With adoption of Cisco Unified Video Advantage 2.2 and later and the VTIII camera, you can elevate your communication experience with support for video communications. Your PC monitor provides support for the video communications while voice communications are supported by your IP Phone 6921 endpoint.
