Sound

Allows you to customize the phone volume for a friendlier user experience:

■ Media volume
■ Ring & notification volume

Display

■ Screen timeout
■ Screen saver

Date & time
■ Automatic date & time: If enabled, date and time are automatically retrieved from the deployed Network Time Protocol (NTP) server.
■ Time zone
■ 24-hour format
■ Date format

Also supported is a simplified version of NTP called Simple Network Time Protocol (SNTP). Both can be used to synchronize device clocks. SNTP is typically used if full implementation of NTP is not required.

See also Configure Time on Teams Devices.

NTP

Preferred NTP server

Administrators can use this parameter to manually define the NTP server, to comply with enterprise security requirements if those requirements preclude using DHCP Option 42. Manual configuration takes precedence over DHCP Option 42 and the time servers. Two ways to manually define the NTP server are available:

■ Administrators can define it in the phone’s GUI.

■ Administrators can alternatively use the parameter 'date_time/ntp/server_address' in the phone’s .cfg configuration file.
