Hi Paul,
I think overall that CUCM 7.x has been a good build so far but there are still some funky bugs floating around. Not show stoppers but....
I would wait a few weeks and monitor the Forums for word on 7.1(2b)SU1 as it was just released on the 14th of September. The 7.1(2) build was quickly deferred :(
Cheers!
Rob
