Callstatus is included for supposed compat with earlier releases, but apparently they put in a non-working callstatus. 4.0 uses SSA(System Status Application) looks nice from the Screenshots in the Tech Bulletin, lots more detail , but can only be ran by 2 users at a time. I wish they would've kept a basic call status application instead of changing to something for the whole shebang, sometimes there are times in an office environment(especially small office, like here) where callstatus is useful to some like the receptionist, but they don't need all the SSA info. from looking at the Screenshots it also looks like they dropped call steal from it..
