I would hold off until at least the next SP release.
There's a bug in 3.2.3 where all phone clocks will be permanently set to a 24 hour clock and it cannot be changed in CMLocal. Also, I am having an issue at two sites where users in DCD are set up with funky user IDs. This is causing issues with our ICD which requires us to manual edit the DCD each time you add a new user.
