We have a remote user that was having problems with his 7945, so he decided to factory reset it. He wiped out the firmware. The phone now goes on a loop trying to upgrade the firmware. This is again a remote user with a home router (which has no DHCP options avail) and no local call manager. What options do I have to recover his phone and have it talk to our call manager? Is there a remote option avail to force the phone upgrade it's firmware from our Call Manager servers?
First of all factory reset does not remove any firmware, it just resets the configuration and deletes certificates.
If there is no DHCP how did the phone get IP address previously? If static then you can add it back onto the phone and define the TFTP server to point to your CUCM TFTP, assuming there is network connection.
There is a DHCP server onsite, just a basic home router DHCP server with no option 66 to point to a CUCM server. The user pressed the 12345678*9# and the phone is stuck on upgrading.
That is what I am trying to do, but not sure how to do this. The phone just reboots and for a few seconds displays the upgrade screen. As far as I can tell, I am unable to do anything. I have tried to click on the setting button and nothing. What combination keys or buttons will let me get to a screen to allow me to input a TFTP server?
