I was asked to add a new holiday to our phone system.   Apparently on a holiday when a call goes to our main phone line there is a schedule that sends the phone call to a different voice mail greeting.  It might just be the regular night mode greeting.
We have MiVoice Office 250 system.
I am looking where I might find the location to enter dates for holidays.  I keep reading that people are using something called STARs to do this.  I don't know what that stands for or where that would be located in the menus.
Thank you.
