I work in a school that has an old Valcom Paging and Bell system
I want to get rid of it.
So I want to setup an extension that will "auto call" specific extensions by time
(e.g. at 9am it will call all classrooms play a 5 sec beep and hangup, and at 10am it will call only grades 1 through 5 play a 5 sec beep and hangup)
Can someone help me ?
