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:
Vacant Intercept
The call normally follows the following Line Overflow programming.
- 3112-01: Direct Termination in the Day (page 819)
- 3112-02: Enable Day Overflow (page 819)
- 3112-03: Day Overflow Destination (page 820)
2. If no, go to the next step for routing.
1. If yes, go to the next step for routing.
- This occurs when 1401-08: Receive DID Calls (page 630) is Yes.
2. If no, the call immediately follows Line Overflow.
- This occurs when 1401-08: Receive DID Calls (page 630) is No.
1. If yes, the call rings the destination extension.
- If unanswered, go to the next step for routing.
2. If no, go to the next step for routing.
1. If yes and the intercept condition is met, the call routes to the Station Intercept destination set up in:
- 2115-02: DID Station Intercept Type (page 748).
- 2115-02: DID Station Intercept Destination (page 748).
2. If yes and the intercept condition is not met, go to the next step for routing.
3. If no, go to the next step for routing.
1. If yes:
- If the extension is unanswered, the call follows Line Overflow.
- If the extension is busy or in DND, the call camps-on and then follows Line Overflow.
2. If no:
- If the extension is unanswered, the call follows Line Overflow.
- If the extension is busy or in DND, the call won’t go through (i.e., caller hears busy).
1. Is telco sending incorrect digits, or is there a DID Translation Table programming error?
2. Is the destination extension allowed to receive DID calls?
3. Is the destination extension available?
4. Is Station Intercept programmed?
5. Is DID Camp-On programmed (1401-09: Receive DID Camp-On (page 631) = Yes)?
