Hi, we are currently researching which version of CUCM we should upgrade to. We are currently 8.5 physical servers and will be upgrading to VM's. The new build will run in parallel however; I thought I would see what other think about which version is really the most stable.
11.1 released Jan 2016 Scares me...too new
11.0 released in Aug 2015 looks like might have some bugs.
10.5 released Dec 2014 looks to have many ES's already.
If you have a moment please share your thoughts.
Thanks,
Ebery
