Hi to all,
i have call manager 7.1.5 and some cisco 6921.
Phones have a preloaded firmware (9.0.2) a nd i would like to downgrade to 8.5.x.
I installed new firmware but phone still run 9.0.2.(also i modified load phone name in device settings)
I have a language issue (6921 won't show thei button in italian while 7942 are ok) and i think it could be a firmware problem.
