Incoming Calls - PRI
When an incoming call is given routing-by-dial-plan treatment, the green LED associated with the appearance of the line lights steadily; the LED does not flash to indicate that the line/trunk is ringing. When an incoming call is on a Personal Line, the green LED associated with the line lights steadily, and ringing on an SA button occurs. The LED does not flash to indicate that the line/trunk is ringing.
Routing by dial plan requires programming of the Dial Plan Routing Table and of the B-channel group (PRI only) or extension to be routed by dial plan.
Call Management System (CMS) does not support routing by dial plan.
Routing by dial plan information appears on 4400-Series and MLX display telephones.
If the number for an incoming call given routing by dial plan treatment is not found, the call is sent to the invalid number destination for DID calls. This can be a dial plan extension number or fast busy tone. If it is a fast busy tone, however, the call is rejected and the network applies an intercept tone.
A PRI line that has been programmed for routing by dial plan should not be programmed for Remote Access or Shared System Access.
