I have a quick question about CUCM CME version compatibility.
my customer is running today CUCM version 6.1 and a couple of CME 7.1 (on 2800 routers) interconnected with H.323.
Now he wants to upgrade his CUCM to 9.X and asks me what version of CME he needs to install. Of course the idea is to say "the latest".
Now the problem is that 2800 routers only support CME up to version 8.6
Did anybody deploy CUCM with CME without having the same versions?
