The Cisco 8841 phone supports Session Initiation Protocol (SIP) for signaling, Session Description Protocol (SDP), IPv4, and IPv6. Optimized for use with the Cisco Unified Communications Manager, the Cisco 8841 phone is a modified version that connects to your network like any other 8841 phones. The difference is the addition of Positive Disconnect On-Hook Security. The phone also allows the on-hook security features to be engaged while in a call providing enhanced “Hold” and “Mute” security.
Speakerphone functionality in DTD-8841-06 and DTD-8841-07 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 8841 can also be ordered with the microphone removed or the speaker disabled.
