Basic DID Call Routing

1. Is telco sending incorrect digits, or is there a DID Translation Table error?

  1. If yes, the call normally follows the following Line Overflow programming (e,g, Vacant Intercept).
    1. 3112-01: Direct Termination in the Day [Lines: Config: Options: Termination (3112): Day Termination: Direct Termination]
    2. 3112-02: Enable Day Overflow [Lines: Config: Options: Termination (3112): Day Termination: Overflow Destination]
    3. 3112-03: Day Overflow Destination [Lines: Config: Options: Termination (3112): Day Termination: Overflow Destination]
  2. If no, go to the next step for routing.

2. Is the destination extension allowed to receive DID calls?

  1. If yes, go to the next step for routing.
    1. This occurs when 1401-08: Receive DID Calls [System: Class of Service: Features: Features (1401): Allow DID Calls] is Yes.
  2. If no, the call immediately follows Line Overflow.
    1. This occurs when 1401-08: Receive DID Calls [System: Class of Service: Features: Features (1401): Allow DID Calls] is No.

3. Is the destination extension available?

  1. If yes, the call rings the destination extension.
    1. If unanswered, go to the next step for routing.
  2. If no, go to the next step for routing.

4. Is Station Intercept programmed?

  1. If yes and the intercept condition is met, the call routes to the Station Intercept destination set up in:
    1. 2115-02: DID Station Intercept Destination Stations: Config: Options: Hunt/Overflow (2115): DID Intercept Destination]
    2. 2114-02: Station Ring Down Type Stations: Config: Options: OffHook (2114): Ring Down: Type]
  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.

Is DID Camp-On programmed?

  1. If yes:
    1. Check to be sure 1401-09: Receive DID Camp-On [System: Class of Service: Features: Features (1401): DID Camp On]= Yes.
    2. If the extension is unanswered, the call follows Line Overflow.
    3. If the extension is busy or in DND, the call camps-on and then follows Line Overflow.
  2. If no:
    1. If the extension is unanswered, the call follows Line Overflow.
    2. If the extension is busy or in DND, the call won’t go through (i.e., caller hears busy).
