The CIS Secure DTD-8841 is a modified version of the commercially available Cisco 8841 phone. The phone supports Session Initiation Protocol (SIP) for signaling for connection to the Cisco Unified Communications Manager or to the Cisco Webex cloud. The DTD-8851 functions just like Cisco 8841 phone, but also has the ability support one additional Keyboard Expansion Module (KEM). The KEM delivers the ability to allow the phone to have any combination of (28) additional line appearances or feature keys such as speed dials. In addition to the TSG positive disconnect mechanisms, the DTD-8851 offers additional options including removable microphone and disabled speakerphone to enhance the security profile of the device.

The DTD-8851 offers programmable line keys which can be configured to support your choice of multiple directory numbers or call features. The 5-in. high-resolution (800 x 480) widescreen VGA backlit color display provides a vivid interface to deliver a simple and intuitive end user experience. Fixed function keys give you one-touch access to applications, messaging, directory, as well as often-used calling features such as hold/resume, transfer, and conference. CIS Secure also offers customized array of faceplates for the phone to ensure that it conforms to your organizations requirements for device identification.
