Feature description
The Incoming DID Digit Conversion (IDC) feature allows digits received
from the Central Office (CO) to be converted to unrelated extension numbers
within the system. This conversion is accomplished using a translation table
dedicated to a Direct Inward Dialing (DID) route. The digit conversion table
is set up to map the received (external) DID digits into the local (internal)
Directory Number (DN).
IDC can be selectively applied to DID routes. A unique conversion table is
available for each route.
