Appendix A

Troubleshooting

This Appendix covers the most likely problems and their solutions.

Overview

This chapter covers some common problems that may be encountered while using the VoIP
Gateway and some possible solutions to them. If you follow the suggested steps and the
VoIP Gateway still does not function properly, contact your dealer for further advice.

General Problems

Problem 1:

Can't connect to the VoIP Gateway to configure it.

Solution:

Check the following:

The VoIP Gateway is properly installed, LAN connections are OK,
and it is powered ON.

Ensure that your PC and the VoIP Gateway are on the same network
segment. (If you don't have a router, this must be the case.)

If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.

If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address within the range 192.168.0.1 to 192.168.0.254 and thus com-
patible with the VoIP Gateway's default IP Address of 192.168.0.250.
Also, the Network Mask should be set to 255.255.255.0 to match the
VoIP Gateway.
In Windows, you can check these settings by using Control Panel-
Network
to check the Properties for the TCP/IP protocol.

If you are using more than one gateway you may have to clear the
cache for the gateways IP address.

1. Go to Start > Run

2. Type “cmd” and press enter

3. On the command line type “ARP –d 192.168.0.250”

press enter

(if using a different IP than substitute that portion of the

command)

.

Problem 2:

Can't connect to the VoIP Gateway, the four Line LED indicators
flash simultaneously for 3 seconds and are off instantly.

Solution:

The flash memory device that stores the firmware was damaged. It is likely
the latest firmware upgrade process was not completed successfully.
You’ll need to return the unit.

Problem 3:

I am using DHCP, and don’t know the IP address that the VoIP Gate-
way obtained from DHCP server.

Solution:

There is a Windows-based utility on the CD ROM named ScanIP.exe. This
utility can detect the IP address of the VoIP Gateway. To detect the IP
