I have a callmanager 4.1.3(sr2) with phones 7912, 7940 and 7960. I bough phones 7911 and I had to install a device package because the model 7911 did not appear in the list when I wanted to add it. The phones 7912 had the corporate logo and after install the device package it has disappear and now the phones has the cisco logo.
I did not install this callmanager but I have to maintenance it and I don't have idea how to solve this problem.
Thanks for your help.
