Check TFTP Settings
Procedure
Step 1
You can determine the IP address of the TFTP server that the phone uses by pressing Applications, then
selecting Administrator Settings > Network Setup > Ethernet Setup > IPv4 Setup > TFTP Server 1.
Step 2
If you have assigned a static IP address to the phone, you must manually enter a setting for the TFTP Server
1 option.
Step 3
If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check that
the IP address is configured in Option 150.
Step 4
You can also enable the phone to use an alternate TFTP server. Such a setting is particularly useful if the
phone recently moved from one location to another.
Step 5
If the local DHCP does not offer the correct TFTP address, enable the phone to use an alternate TFTP server.
This is often necessary in VPN scenario.
