Full Commercial Overview

The Cisco IP DECT 6825-R (full ordering PID: CP-6825-RGD-3PC-K9, abbreviated as 6825-R-K9) is the ruggedized industrial variant of the flagship premium Cisco IP DECT 6825 cordless handset within Cisco’s IP DECT 6800 Multiplatform (MPP) collaboration ecosystem. The suffix breakdown defines core specifications:

1. 6825: Premium enterprise DECT handset base model
2. -R / RGD: Ruggedized industrial IP65 protected chassis variant
3. 3PCC: Third-Party Call Control open-standard SIP firmware, fully interoperable with Webex Calling, BroadWorks, Asterisk, Metaswitch and all mainstream hosted SIP PBX platforms, independent of Cisco CUCM enterprise call managers.

This ruggedized handset is purpose-built for harsh industrial, manufacturing, warehouse, food service and healthcare environments exposed to dust, moisture, splashing water and minor physical impact—workspaces where standard office plastic handsets would degrade or fail prematurely. Its most recognizable visual marker is a bright orange accent band around the midsection, making the device easy to locate on busy production floors or storage areas.

All core premium feature set of the standard 6825 is retained, with exclusive industrial hardening upgrades unique to the 6825-R ruggedized variant:

1. IP65 Ingress Protection Rating: Fully dust-tight construction and resistant to low-pressure water spray from any direction, protected against cleaning splashes, warehouse dust, kitchen liquid spills and clinical sanitizer mistCisco.
2. Reinforced thick polycarbonate ABS textured rugged chassis, shock-resistant for minor drops and workplace bumps.
3. Built-in vibration alert mode for noisy industrial zones where ringtone audio cannot be heard.
4. High-visibility orange chassis band for rapid visual identification in large busy facilities.

The 6825-R pairs exclusively with Cisco DBS-110 single-cell base stations, DBS-210 enterprise multi-cell base stations and RPT-110 DECT signal repeaters, supporting uninterrupted seamless cross-cell roaming across large campus-scale industrial networks without dropped active voice calls. Each ruggedized handset supports up to two independent SIP line registrations, delivers crystal-clear G.722 HD wideband voice quality optimized for loud industrial background noise, and features extended all-day lithium-ion battery runtime. All handset firmware can be remotely pushed and upgraded wirelessly over DECT radio links from connected base stations, enabling centralized mass device management across full enterprise DECT voice networks.
