Been having some issues recently with phones dropping off the call manager and then refusing to re-register. The phone logs are showing TFTP NOT AUTHORIZED, a reboot of the phone brings it back online.
I am wondering why this has started happening seemingly out of the blue and if it is a sign of something about to go wrong. We are not using security on your phone system and none of the phones have a CTL file installed.
It's happened on two different 9.1 clusters both within a day or two of each other, both using different TFTP servers.
Can you get this error message for non CTL related issues?

the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
