The Cisco Unified Wireless IP Phone 8821-EX Cordless Extension Handset is designed for workers whose roles are in more rigorous, industrial settings. It is Ingress Protection standard (IP54) 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 5 feet, to help ensure shock resistance and avoid breakage if dropped.
