All of our 54xx phones download their firmware after every reboot of the phone system. At one point I ran the turn_on.bat to get all of our phones to the same level of firmware. I have run the turn_off.bat procedure from the manager directory 3 different times and received the "successful" message and rebooted the phone switch. One time the phones didn't download their firmware after the reboot. The following day I rebooted the phone system and again the phones downloaded the same firmware that was already on them. Does the turn_off.bat not work 100%?
