Administering trunks for listed directory numbers
Listed directory numbers (LDN) are the phone numbers given for an org ani za ti on
in public telephone directories. You can administer DEFINITY ECS so that calls
to different listed directory numbers go to the same attendant group. How you
administer your system for LDN calls depends on whether the calls are comin g i n
over DID and tie trunks or over CO and FX trunks.
Instructions
As an example, let’s say that one attendant group answers calls for 3 different
businesses, each with its own listed directory number:
■Company A — 855-2020
■Company B — 855-1000
■Company C — 855-1111
DID trunks and some tie trunks transmit part or all of the dialed digit string to the
switch. If you want these calls to different numbers to go to one attendant group,
you must identify those numbers for the switch on the Listed Directory Numbers
screen.
