I'm looking to upgrade our CallManager cluster from v6.1(2) to a later version (we have several 'bugs' that later versions allegedly fix). The problem is, there are quite a few versions of CUCM after 6.1(2), and nothing overly obvious on the Cisco site to explain which of these i should/shouldn't be trying to use...
6.1(2) (three versions)
6.1(3) (three versions)
Ought i to use 6.1(3) or a later release, perhaps 6.1(3b)...? There are also some "SUI" releases which confuse me too...
Anyone able to offer an explanation of what the differing versions of CUCM offer?
