I've got a callmanager 4.2 that i want to use in addition to the firealarm system in the office. I want the receptionist to be able to call up everyone (300 numbers), and i want it to not stop ringing before they pick up the phone.
I want it to be automated as much as possible, single button press from the receptionist and a pre-recorded message when they pick up the phone.
Is this possible to do without an additional install or purchase? Is this a feature on the callmanager?
