As an alternative response when the telephone or door bell/chime is heard, 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 from Inside the Building

To initiate a call to the door, the person within the building simply takes the telephone off-hook and hook-flashes the telephone within the first 4 seconds. At this point, there will be direct two-way communication from within the building to the door speaker.

Telephone Line In Use When Visitor Presses Door Speaker Button

Once the push button is pressed, you can “Hook Flash” to the door speaker and then back to the original call only once, unless the push button is pressed again.

If you forget to hook-flash back to the original call, the AT&T Door Phone Controller will call you back.

If a visitor presses the door speaker button while an existing call is already taking place on the C.O. line, the AT&T Door Phone Controller will generate a “door alert” signal to indicate a visitor needs attention at the entrance. The person inside the building can hook-flash the phone and be in direct two-way communication to the door speaker. Then normal AT&T Door Phone Controller functions can take place. When door phone functions have been completed, i.e., door has been remotely opened, hook-flashing the phone again within the forced disconnect timeout (or pressing 9) will return the line back to the original call. This feature operates much like a call-waiting function.
