[cisco-voip] Upgrading to 8.5(1) CUCM

[Anthony Kouloglou]

  Thanks Lelio,
i understood what you said about licensing and contracts.
But, i would like to know apriori if possible that, if i have upgraded 
to 7.1.5 i would have to wait for the 8.5 because you cannot upgrade 
from 7.1.5 to 8.0.
Is this info for the next versions of 8.5 somewhere?

Thanks a lot
Anthony
