I have a very strange situation with my CUCM 7.1.5
I install the most recent firmware for them on CUCM
new firmware versions are located in right positions in Device - Device Settings - Device Defaults
but reset and reboot of the phones do not force them to get a new firmware.
the same situation is with the ringtones. No ringtones are available from CUCM.
But. If I do a hard reset everything become fine. Phone get a new firmware. And ringtones from CUCM become
Phones are 7911, 6921, 7942.
And the picture with 9951 is more interesting. They start to boot till the word AUTO-REG and go to reboot...
Hard reset fixes the problem. (Of course, Auto-registration is disabled on a publisher and subscriber).
I don't want to hard reset every phone in the office.
And I want to understand what's wrong.
Please help to understand.
Solved! Go to Solution.
As I understand by default phone have to take the default firmware during the reset of reboot.
but yes I inserted names of new firmare in "phone load name". and without success.
Could you share the default load on these phones and the version which you tries to upgrade. Did you upload the files to all the TFTP nodes and then a restart of the service ?
Hope this helps!

And TFTP service is activated only on publisher. All my info is about publisher.
