[cisco-voip] CUCM Version naming conventions

[afatsum]

Hi,

Can anyone tell how the version naming of CUCM in compatibility matrix 
i.e. 7.1.2a corresponds to actual version displayed on the admin page 
i.e. 7.1.2.2000-2?

What I am trying to figure out is how to check the version in 
compatibility matrix, as its listed 7.1.2a from the version listed on 
the admin page of CM, so i would know if its an ES, SU or what upgrade 
path is available to me.

I've googled it, and didn't find any useful reference information on 
Cisco.com either.

Thanks in advance
