We have 14 buildings. 2 buildings have SX2000's that have been migrated to 3300 MXe controllers and have a mix of IP and digital phones; 3 others have 3300 MXe controllers and IP phones only, and the remaining 7 are 3300 CX controllers. All are running software version 5.0. Can anyone tell me what exactly Enterprise Manager does for us? We login to it in order to access all of the controllers, but other than that, I'm foggy as to what it does, especially since Ops Man is no longer being used. We're considering virtualizing it but not sure if it is worth it?
