No. Dgts Subaddress
Allows a caller to reach a number where switch 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.
