Administering Trunks for Listed Directory Numbers

Listed directory numbers (LDN) are the telephone numbers given for an organization in public
telephone directories. You can administer Avaya Communication Manager 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 coming in over DID and tie trunks or
over CO and FX trunks.
Instructions
As an example, let us 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 Communication
Manager. If you want these calls to different numbers to go to one attendant group, you must
identify those numbers for Communication Manager on the Listed Directory Numbers screen.
We will take the 3 businesses listed above as an example. We will assume your server receives
4 digits from the central office on a DID trunk group and that you're not using Tenant
Partitioning. To make these calls to different listed directory numbers terminate to your
attendant group:
1. Type change listed-directory-numbers and press Enter.
