call a door phone

Door Phone(s)
Door phones can be used to call phones selected in system programming. When a door phone calls, you hear a distinctive ringing tone, one or five times (set in system programming). You can also call a door phone and monitor the surrounding area.
LCD telephones display the door phone name ID when calls are made to or from door phones.
The number of possible door phones varies by Strata CIX system, 01~24 maximum for larger systems. Check with your System Administrator to find out the names and locations of your system’s door phones and record them below.
