DID Call Handling
The following steps illustrate how the system handles DID calls when the call  is not intercepted by an exten-
sion’s Call Forwarding or Extension Hunting.
Basic DID Call Handling
1.If yes:
V
acant Intercept
The call normally follows the following Line Over flow programming.
- 3112-01: Direct Termination in the Day  (page 819)
- 3112-02: Enable Day Over flow  (page 819)
- 3112-03: Day Over flow Destination  (page 820)

How Call Forwarding and Extension Hunting Interact with DID Calls
The following chart summarizes how the system handles unanswered DID calls when Call Forwarding and/
or Extension Hunting are enabled at an extension. For the specific routing details, see:
❥DID Call Handling with Call Forwarding and Extension Hunting  (page 103).
❥DID Station Intercept and Line Overflow  (page 105).

DID Call Handling with Call Forwarding and Extension Hunting
The following two tables show the detailed interaction between Call Forwarding and Extension Hunting for 
unanswered DID Calls. These interactions occur when an extension user enables Call Forwarding and their 
extension is already part of an Extension Hunting group.

DID Station Intercept and Line Over flow
The following table shows the detailed interaction between DID Station Intercept and Line Over flow for unan-
swered DID Calls. These interactions occur when an extension has DID Station Intercept ena\
bled, the DID line 
has Line Over flow enabled, and the call is not intercepted by either Call Forwarding or Extension Hunting.

Basic Programming
1.Be sure your T1 PCB is installed and connected and that your telco is providing T1 DID service.
2.In 3101-01: Line Type  (page 809), enter the correct circuit type for each DID line:
-
03 for DID Wink Start
-
04 for DID Immediate Start
3.In  3101-03: DTMF Dialing  (page 811), indicate whether the line is DTMF (1) or Dial Pulse (0).
4.If your telco provides DID service using E&M Wink Start DTMF signaling, choose...

- In  3121-04: Number of ANI Digits  (page 826), specify the number of digits the telco provides in the 
ANI number ( for option 1 above only ). This program does not apply to options 2-4 above.
2.If no, in 3121-01: Caller ID Type  (page 825) do not enter 3 to enable ANI-based Caller ID for the line.

Features
Direct Inward Line
Description
A Direct Inward Line (DIL) is a line that rings an extension directly. Since DILs only ring one extension, 
employees always know which calls are for them. For example, a company operator can have a Direct 
Inward Line for International Sales Information. When outside callers dial the DIL’s phone number, the call 
rings the operator on the International Sales line key. The DIL does not ring other extensions....
