I just upgraded our lab again from 6.0.1 to 6.12.1132 and again if I switch back to the older version the handsets just show registering even if I stop , restart dbreplication- The handsets upgrade their phone load when I switch after the prgade to 6.1.2 all ok and work, if I switch back the phone "downgrade" themselves ok but sit on registering
I`ve done this twice with the same results- Any idea`s.
