The Cisco 8851 phone without 18/36 Key Expansion Module supports Session Initiation Protocol (SIP) for signaling, Session Description Protocol (SDP), IPv4, and IPv6.  The phone is optimized for use with Cisco Unified Communications Manager.   This Cisco 8851 phone is a modified version that connects to your network like any other 8851 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 on-hook security can be manually disengaged after an off-hook condition is established (Manual mode) or triggered automatically via the hook switch (Auto mode).  The mode is set at the factory and must be specified at time order.  The security re-engages automatically once any on-hook status is established.
