Troubleshooting Tips

This section assists you with problems you may encounter while installing the 6400-S.

Trouble accessing the Internet

We recommend connecting a PC either directly or through a switch to the Port 1 of the 6400-S. The default IP address of the 6400-S is 192.168.1.1 so please be sure that the IP address of the PC is on the same network (eg. 192.168.1.2).

Once you have connected please verify that the IP configuration information in the Network page is correct. Some other items to try:

Ping the Port 2 interface of the 6400-S from the attached PC

Ping the DNS server for your network. Sometimes connectivity problems occur when the domain name being used cannot be mapped to the proper IP address.

Ping a well known address on the Internet.

Ping the IP address of the softswitch.

No dial tone

If don't hear a dial tone when off hook:

Check the configurations on the VoIP ALG page.

Make sure the ALG registration code is configured.
