Physical Equipment Troubleshooting:

1. Confirm that the Ethernet cable is plugged into the correct Ethernet port on the phone (looks like 3 computers

connected) and the other end is plugged into your network.

2. Swap out the port being used to connect to your network.

3. Swap out the cabling being used with the phone.

4. Verify the DNS server is an outside public DNS server. If the DNS server is local, turn off DHCP to statically set an

IP address on the phone. You should use the same IP address, subnet mask, and default gateway as you
previously used. Set the DNS server to 8.8.8.8 and hard set the TFTP server.

Additional Information

If your phone still does not have a connection please contact support with the following information.
