I have been running CUCM 18.104.22.16800-2 for about a month now, and ran into the problem today that any updates that I make to phones will not take effect.
In addition, when I delete a phone, and go as far as a hardware reset (hold down # on startup) the phone will still register as normal.
Phones are registering fine, and are functioning, I just cannot make a change.
I have restarted tftp, and dbl. This is a single server deployment, so all the phones are registered to the only PUB.
What else should I look at?
we restarted RIS, DBL, ACISCODB and TOMCAT. at the time the guy was not willing to restart CCM, so that's the only one we could not try. later on during the night he rebooted the server but the traces were not enabled so we could not get a root cause
you can try those services, maybe with you they do the trick
if this helps, please rate
