The Cisco 8821 is designed for workers whose roles are more rigorous, for example Doctors and Nurses. Operations and Engineering Staff in Manufacturing, Customer Services Representatives in Retail or workers on Rigs in Oil and Chemical Industries.
Sleek, Lightweight & IP67 Rated
Whilst the Cisco 8821 is sleek and lightweight, the design is hardened for users. It is Ingress Protection standard (IP67) rated and is sealed for protection against dust, splash and water. The device is also MIL-STD-810G tested, with a dozen drops onto concrete from heights of up to 6 feet (1.8 m), to help ensure shock resistance and avoid breakage if dropped.
Enhance Security
The Cisco 8821 enhances security and simplifies configuration management. Stronger encryption is supported for certificate management and policy enablement with the support of Secure Hash Algorithm 2 (SHA-2). Simple Certificate Enrollment Protocol (SCEP) eases IT administration by enabling automatic certificate management on the device.
High Resolution Colour Display
End users will enjoy a larger, higher-resolution colour display and a user experience that is common with Cisco IP Phone 8800 Series desk phones. In addition, roaming between access points within the campus will support more seamless voice communications with the 8821’s support of Fast Transition (802.11r). This protocol was specifically designed for mobile voice over IP (VoIP) communications devices within Wi-Fi networks. Bluetooth is supported for the user’s choice of third-party wireless headsets and adds freedom by untethering the user from the handset.
The 8821 supports Cisco and/or third-party XML applications such as push-to-talk.
