Ensure that calls are answered and that callers' needs are met. You can add greetings, set up menus, and route calls to an answering service, a hunt group, a voicemail box, or a real person. You can create a 24-hour schedule or provide different options when your business is open or closed.
To configure your IVR (Interactive Voice Response) options with a brand-new audio file greeting at any time. You can record and select greetings to play on specific holidays in advance. Let callers know that your office is closed for a holiday. (See this article to set up a holiday schedule for your Auto Attendant.) Promote special sales and offers for callers to hear on selected dates, before the caller selects a menu option. Prepare special IVR instructions for callers on specific dates, when you anticipate a high call volume.

Also note, this system works over your NETWORK (not your phone wires). It will connect to up to 4 standard phone lines (or Internet-based VoIP service) but the connection between the phones and the UCM6204 "base" are done over a Ethernet NETWORK. The bad news is that if you only have phone lines running everywhere (2 or 4 wires only) then you will have to run new wiring. The good news is that if you already have a computer network and computers at each phone location, these phones can be connected to that existing network. (If you only have one network jack per location, the phones' built-in network switch lets you "pass" the network connection through the phone to your computer so both can be connected).
