Note: If the time displayed is not the same as the actual lo-
cal time, this is due to the time zone setting. Select the Time
Zone tab in the
Date and Time Properties dialog and con-
figure it for the current location. If you receive an error mes-
sage, the Internet access router may be blocking communi-
cation at UDP port 123. In this case configure a NTP server in
the LAN.
Tip: If the time service cannot be activated, the corresponding
Windows service has not been started. Select the
Perform-
ance and Maintenance category in the Windows control
panel. Start the Services program in the Administrative
Tools folder. If necessary, restart the Windows Timer Server
service.
3.6.5 Checking Internet Connection
The Aastra 800 communications system requires an Internet connection if you
wish to operate SIP lines via SIP provider or external Q.SIG-IP bundles. Because the
Aastra 800 communications system uses the Windows operating system network
functions you have to configure the Internet connection for Windows XP.
Tip: For more information on this topic, please refer to the Win-

In your LAN you usually use an Internet access router that offers Internet access to
all LAN computers. In this case it is sufficient if the IP address of the Internet access
router is listed in the settings for the standard gateway and the DNS server (see
Configuring a Fixed IP Address starting on page 24). Follow these steps to check the
Internet connection:
1. Select All Programs: Accessories: Command Prompt in the Windows start
menu.
2. Enter “route print” and confirm with the enter key. The IP address of the
Internet access router must be shown in the “Standard gateway” line.
