Screen Reference
No. Dgts Subaddress
Allows a caller to reach a number where the media server's digit processing deletes the dialed
number and inserts the listed directory number (LDN). The LDN then is sent to the destination
address and the dialed extension is sent in the calling party subaddress information element
(IE). At the receiving end, the call terminates to the user indicated by the subaddress number
instead of the attendant. Administrable when, on the
screen, the ISDN Feature Plus field is y.

Usage
Enter the 3-digit Numbering Plan Area (NPA) (or area code) for the

unless the Local Exchange Carrier requires 10 digits for local NPA calls.
