Door Box

Your system may have Door Boxes. A Door Box is a self-contained Intercom unit typically used to monitor an entrance door. A visitor at the door can press the Door Box call button (like a door bell). The Door Box then sends chime tones to all extensions programmed to receive chimes. If you receive Door Box chimes, you can just lift the handset to answer them. You can then talk to the visitor at the door.

Door Boxes come in handy at delivery entrances. Your company doesn't have to have someone at the door to monitor the entrance. You can just answer the Door Box instead. If the door has an electric strike, you can even use your telephone to release the door.
