Administering Trunks for Listed Directory Numbers

If your service provider sends 7 digits but you only need 5, you need to absorb the first 2 digits in the
digit string. To absorb digits:
1
Type change trunk-group 5 and press
The Trunk Group screen appears.
2
In the
Digit Treatment
This field tells Communication Manager to remove digits from the incoming digit string. These
digits are always removed from the beginning of the string.
3
In the
Digits
For absorption, this field defines how many digits will be absorbed. Communication Manager will
remove the first 2 digits from the digit strings delivered with incoming calls. For example, if the
central office delivers the string "556-4444," Avaya Communication Manager will change it to
"64444," an extension that fits your dial plan.

Administering Trunks for Listed Directory Numbers
Listed directory numbers (LDN) are the phone 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.
