Direct Inward Dialing (DID)
Interactions
The following features interact with Direct Inward Dialing.
Attendant Camp-On: DID calls are not provided Attendant Camp-On treatment. They will not
appear on the Direct Trunk Attendant Console Return-On-Busy or Return-On-Don’t-Answer
buttons or on the Switched Loop Attendant Console Loop buttons unless they are first answered
at the attendant position and are subsequently extended by the attendant.
Attendant Direct Extension Selection: Selector Console LEDs respond to DID calls just as
they do for other outside calls. When a user answers a DID call, the associated LED on the
Selector Console will light steadily. When a DID call arrives at the attendant position for
coverage, the LED associated with the coverage sender will flash and will then go dark when the
call is answered. However, if the call is placed directly to the attendant position or is forwarded to
the position and thereby arrives on a System Access button or a Loop button (e.g., if a DID PDC
is signed-in at the attendant position), then no LED indications on the Selector Console will be
provided. If a DID call is directed to the answering position and is subsequently extended to a
station, then the LED on the Selector Console associated with the station will flash if the call
returns to the answering position. The LED will light steadily if the call is answered by the station.
Call Waiting: Incoming DID trunk calls do not wait at busy stations; they receive busy tone.
Conference: For conference purposes, DID calls count as one of two allowable outside parties.
Coverage: DID calls receive standard coverage treatment.
Dictation System Access: A DID number may be associated with the dictation system access
code. This allows an outside caller to access the dictation equipment.
Direct Group Calling: A DID call will be directed to a DGC group if the DID number matches the
DGC group access code.
Night Service: DID calls do not receive Night Service treatment. A DID call will ring at the
appropriate station whether Night Service is activated or not.
Off-Premises Stations (OPS): DID calls can be directed to OPS.
Paging System Access: A DID call may access a paging zone. This allows the user to dial in
and utilize the Paging feature. Dial restricting the paging code will block this interaction.
Personal Dial Codes: DID calls will be redirected to PDCs signed in at other terminals in the
system. DID calls to an unassigned PDC or a FPDC that is not signed in will be either redirected
to the attendant or receive Reorder Tone.
