11. Trouble Shooting for Web Configurations
11.1. DO NOT HEAR DIAL TONE?
The phone port of VS211 is set to VoIP mode at default. When you pick up the phone and hear
a busy tone, it indicates the WAN port is NOT connected. Make sure the ADSL Ethernet cable is
connected to the WAN port of VS211 and Power Reset again. You may press 0
* key to switch
to PSTN line, and you should hear another dial tone from PSTN. If not, please make sure the
PSTN line is connected to the LINE port.
11.2. CAN NOT ACCESS WEB PAGE?
IE Web Browser is a useful tool to configure VS211. When you have difficulties in accessing the
default IP address http://192.168.123.1 of VS211 as in the following figure, the most possibility is
that the PC might have different subnet IP settings from 192.168.123.xxx. In this case, you must
change VS211 IP address to the same subnet as PC and NAT router.
Example: To change VS211 IP address to the same subnet as PC and NAT router
1. Pick up the phone and press #111# from the phone to enable DHCP Client mode. VS211 will reboot,
and LED will start flasing to get an IP address from NAT DHCP server.
2. Pick up the phone and press #120# to obtain the VS211 IP address from telephone IVR, for
example, 192.168.62.51.
3. Enter from IE web browser http://192.168.62.51 to login VS211 web page for configurations.
