personally i'd recommend CCM 4.2(3) latest SR

i have that at my lab and i've had little issue with it so far (over a year since i installed)

it's the latest version still running on W2K platform and so far i'd say it's the most tested

there were some bugs like a CDP error which was annoying but it's solved by now but i don't know of any major bug for this

if you want some documentation you can use this

Upgrading Cisco Unified CallManager Release 4.2(3)

if you wish to test a new platform (linux) i'd recommend CUCM 5.1(2)
