Check TFTP Settings
Procedure
Step 1
You can determine the IP address of the TFTP server used by the phone by pressing Settings, choosing Network Configuration > IPv4 and scrolling to the TFTP Server 1 option.
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. See Network Configuration Menu.
Step 3
If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check the IP address 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 was recently moved from one location to another. See Network Configuration Menu for instructions.
