Which Version of Unity Express

Is required if running CCME 4.2?
Where on the Cisco site can I find which version is compatible with the CCME version? Have trawled through it, but getting nowhere!
Thanks

It's a 3825 router.
Looking at the matrix, it seems to be dependent on the module installed.
NME-CUE
NM-CUE-EC
NM-CUE
AIM-CUE
AIM2-CUE
Is there a way to check what type of card is installed? The router is remote.
