• Multicast Address—Used by the Cisco SPA9000 to communicate with
Cisco SPA IP phones. Defaults to 224.168.168.168:6061. (The
Cisco SPA501G, can be configured by using the IVR. See the “Using IVR on
IP Phones Without Screens” section on page 30.)
• Key System Auto Discovery—Enables or disables auto discovery of the call
control server (for example, the Cisco SPA9000). Disable this feature for
teleworkers or other scenarios where multicast does not work.
• Key System IP Address—IP address of the call control server IP. Enter the IP
address for teleworkers or other scenarios where multicast does not work.
• Force LAN Codec—Used with the Cisco SPA9000. Choices are none,
G.711u, or G.711a. Defaults to none.
• Auto Ans GrPage On Active Call—Used with the Cisco UC320. Allows you
to enable or disable “auto answer” of a group page when there is an active
call on the phone. When set to yes (the default), a group page is
automatically answered by the phone even if the user is on an active call.
When set to no, the page is not automatically answered.

Enabling Call Features
This section describes how to enable and disable call features on the phone.
Enabling Secure Calls
The phone can encrypt calls to protect them from eavesdroppers. The dial pad
codes for encrypting calls are:
• *16—Secures all calls.
• *17—Disable the call security the user enabled by dialing *16.
• *18—Secures an individual call when dialed before or during a call. Using
this star code is redundant if all outbound calls are already secure by
default or from having dialed *16.
