The Cisco 8841 phone supports Session Initiation Protocol (SIP) for signaling, Session Description Protocol (SDP), and IPv4 and IPv6. The phone is optimized for use with Cisco Unified Communications Manager. This Cisco 8841 phone is a modified version that connect to your network like any other 8841 phone. The difference is the addition of Positive Disconnect On-Hook Security. Approved for use in SCIF and SAPF environments, the phone also allows the on-hook security features to be engaged while in a call providing enhanced “Hold” and “Mute” security. Speakerphone functionality is enabled on the device and is protected with the on-hook security of the positive disconnect electronics, but can be administratively disabled in the Unified Communications Manager.
The TSG audio on-hook security can be manually disengaged after an off-hook condition is established (Manual mode) or triggered automatically via the handset hook switch (Auto mode). The mode is set at the factory and must be specified at time of order. The security re-engages automatically once any on-hook status is established.
