Direct-In-Dialing

System Feature

 

Definition

The incoming public external line calls can be routed directly to extensions with Direct-In-Dialing.

Settings

Type of signaling indication of origin and rerouting in certain traffic cases are set by the administrator.

Procedure and function

The extension number is transmitted from the public exchange. The digits are analyzed to find out whether the extension has a CoS that allows Direct In-Dialing.

Note: The call can be rerouted (for example, to an operator who gets information about the dialed number and reason for rerouting) if congestion occurs, or if the extension is not answered, busy, vacant, blocked for Direct In-Dialing or in line-lockout state.
