How to find the major differences between call manager versions, starting from 8.5 to latest

[Syed]

Hi All,

I would like to know how could I differentiate/compare any given call manager servers?? And also know prerequisite before choosing version? 

Thank you in advance...

Read the RNs from each version, they contain that info, I'm assuming you were expecting a doc outlining all that, but that's not the case.

To choose a version you need to know which ones are being sold and shipping, then it's really up to your HW, features required, and preference.
