Adjusting Video Encoder Quality
You can adjust the quality of the video image sent to the far end during a call by specifying a relative lower or higher resolution in the Administrator Preferences : Video : Video Quality : Video Encoder Quality preference. Moving the slider to the right decreases the resolution of the video sent to the far end and improves the quality of the video image. Consider using this preference to make minor adjustments to the quality of the video image sent to the far end.
Disabling Access to the Local Directory
By default, users can place calls using entries in the local directory and add, remove, or modify these entries. For more information, refer to “Placing a Call from the Directory” on page 14.
Administrators can disable user access to the local directory by setting Local Directory to Disabled in Administrator Preferences : Directory : General. Disabling access to the local directory also disabls the following:
•saving entries from the REDIAL list to the local directory
•copying corporate directory entries to the local directory
Administrators maintain access to the local directory on the web administration interface Directory page when the Local Directory preference is set to Disabled. For more information about managing the local directory from the web administration interface, refer to “Using Advanced Directory Features” on page 54.
