Based on the Cisco 9861, the CIS Secure DTD-9861 combines advanced collaboration features, strong encryption, and a robust feature set supporting modern workflows while aligning with the operational and security expectations of secure facilities. As the successor to the Cisco 8841, the 9861 enables new capabilities including a customizable action button and simplified hot-desking. Built for reliability, clarity, and scalability, the DTD-9861 is ideally suited for deployment in government offices, defense agencies, secure areas, and controlled-access environments where clear communication is essential.

The DTD-9861 is a flexible desktop voice endpoint capable of bridging the gap between hybrid work, calling, and meetings while enabling a simplified end user experience. The DTD-9861 does this by running the new Cisco PhoneOS operating system allowing a single flexible OS to work with your choice of Cisco Unified Communication Manager (CUCM), Webex Calling, Broadworks, or other 3rd party on-premise or cloud calling platforms. Coupled with Cisco provided hardware-enabled security, runtime protection and application security, the TSG compliant DTD-9861 provides the positive disconnect capabilities to deliver the software and hardware based protection needed in secure spaces.
