Answering a Call From the Door Speaker
When a person inside the building hears the telephone ring
and/or the door bell/chime sound, he can simply respond by
answering the ringing phone. At this point, the AT&T Door
Phone Controller will establish two-way communication with the
door speaker. To open the door, the person inside the building
either enters the Door Code on the telephone’s keypad or
presses the door-unlock push button. Either of these actions
presses the door-unlock push button. Either of these actions
will activate the customer provided electric door strike plate
device.

bell/chime, the person inside the building can press the
door-unlock push button which will stop the ringing and will

open the door. This allows the door to be unlatched without the
use of a phone.
Calling the Door Speaker
To initiate a call to the Door Speaker, the person inside the
building simply takes the telephone off-hook and accesses the
trunk connected to the AT&T Door Phone Controller.
