I have Cisco 3800 voice bundle and phone 7975g, When I connect the phone to the network it is try to communicate with CME but it did not register, when I checked the massage status inside the phone it shows "Can't find file:...cfg.html", I reset the phone to the factory default, when it boot it is try to upgrade the image but it shows error, and keep booting without any image. What is the solution for this?
The firmware is erased from the phone when you perform a factory reset. The phone needs to be able to retrieve this from the CME TFTP server. Once that is done, it will then look for it's configuration file. This needs to be generated once you have properly configured the phone and directory numbers.
Thank you all for your help. I had solve the problem. I just download the image for the phone 7975g which is compatible with on CME 7.1 then I typed this command TFTP-server flash:term75.default.loads then the phone download this image.
