If the number is a VDN extension

The following events occur:

  • Vector processing terminates within the current vector and the call is removed from any queues.

  • Any call-related data such as dial-ahead digits and collected digits remain with the call.

  • If the current VDN is administered with override, the new VDN overrides current VDN information.

  • Processing of the vector associated with the routed-to VDN extension begins.

If the number is an AAR/ARS FAC plus digits, or if it is a remote Uniform Dial Plan (UDP) extension

Standard Automatic Alternate Routing (AAR) / Automatic Route Selection (ARS) processing is performed to select the trunk group and outpulse the digits. If a trunk is seized, vector processing terminates, and the calling party hears feedback provided by the far end. Otherwise, the call cannot complete successfully because no trunks are available, the Facility Restriction Level (FRL) / Class of Restriction (COR) is restricted and vector processing continues at the next vector command.

If the number is a Trunk Access Code (TAC) plus digits, and a trunk is seized

Vector processing terminates, and the calling party hears feedback provided by the far end. Otherwise, the call cannot complete successfully (because no trunks are available, the COR is restricted, etc.), and vector processing continues at the next vector command.

If the number is any other number, such as an FAC other than an AAR/ARS or Service Observing

The command is unsuccessful, and vector processing continues at the next vector command.
