3.6.4 Configuring SNTP Time Service

VoIP terminals hooked up to the Aastra 800 communications system are set to the
current time using the SNTP (Simple Network Time Protocol) time service. The
SNTP service of the Windows operating system is used to do so. The server oper-
ation mode of the Windows time service of the Aastra 800 communications
system installation program is activated to enable VoIP terminals to query the
current time.
Check the Windows time service function and configure it if necessary. To do so,
you must be logged on as a user with administrator rights.
1. Double-click on the time display in the system tray of the task bar.
2. Select the Internet Time tab in the Date and Time Properties dialog.
3. Activate the Automatically synchronize with an Internet time server option.
Dialog: Date and Time Properties
4. Enter the address of a valid NTP server into the Server field. This could be the
"time.windows.com" server offered by Microsoft.
5. Click on the Update Now button. After a brief interval, the successful time syn-
chronization should be displayed in the dialog.
Note: The server operation mode of the time service is usu-
ally deactivated in Windows XP. The time service is by de-
fault only for querying the time.
