Question about Cisco 7940 IP Phone
the DHCP server should be providing the address of the TFTP Server as DHCP Option 150. The most likely problems are:
Option 150 not defined, or not the correct IP address of the TFTP Server.
Or possibly your TFTP Server is not functioning properly.
If you have not Option 150 defined, the phone will use the default gateway as the TFTP server address.
