I tried to update the firmware of phones 88xx and 7821 series .
I have uploaded the new firmware and restarted the TFTP however the new firmware still not shown in device default.
cucm ver 12.01
files are uploaded and installed (cop.sgn) format successfully
also tried to extract the files and uploaded them individually but also still not exist under "Device Defaults"
Solved! Go to Solution.
Follow the steps the in this guide to fix the firmware default for your phones, look at the very last section of the doc, you'll see a pic with "dual bank information". I know you did not install the device pack but it's the same concept.
I tried the same but still can't see the new firmware in device defaults.
I installed transit firmware then install the required firmware and it is done .
current load image : 12.0.1
transit image : 12.1.1
required image : 12.5.1
I am not sure this was the issue or not.
currently the next step is to apply the new image on phones.
so I have to reset all phones to do so . correct ? or phones should start upgrading themselves?
