I'm thinking of upgrading to Unity 4.2.1 (from 4.0.5), and I am interested to hear any opinions regarding the stability of this release. This will be for a VM only server, integrated with CallManager 4.1.3, for about 1000 users.
I know that there were some issues with the early 4.0.x train, and I am hoping to avoid any surprises.
Re: Stability of Unity 4.2.1? Looking for opinions.

Actually more features you can use in 4.2. But the end user interface or expierence is the same. You can add more options such as Alternate Contact Number in their greeting which is handy.
The upgrade is pretty painless also. I downloaded the software, pulled a drive and upgaded on the box from 4.05 to 4.2. takes awhile to convert the databases, but it's been running for 2-3 months knock on wood.
