• Door phones cannot be members of a hunt group or call coverage group.
• Door phone calls are not subject to barge-in (Busy Override), regardless of
the extension’s program settings.

Receiving a Door Phone Call. When a visitor presses the door phone
button, an intercom call is generated automatically to the extension(s)
assigned to ring for a door phone call.
• If the extension is on-hook, the visitor will hear ringing tones. The tones
will stop when the extension user answers the door phone call.
• If the extension is busy, the door phone call will ring in as a normal call
(for example, the extension user will hear a “beep” in the receiver, indicat-
ing another call) -- and the visitor will hear silence. When the extension
user hangs up, a call will be established between the door phone and the
extension (it will either ring or establish an intercom voice path, depending
on the extension’s programming).
