Appendix

This section contains possible solutions to problems regarding the installation 

of the 4300T. 

We recommend connecting a PC directly (or via a switch) to the LAN port of 

the 4300T.  The default LAN IP address of the 4300T 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 WAN interface of the 4300T 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 remote softswitch or IP PBX.

• Verify the configurations on the VoIP ALG page.

• Check that the ALG registration code is configured.

Select registration code.

• Attempt to ping the softswitch using the ping tool in the web GUI.
