Inserting and Absorbing Digits
Use this procedure to modify the incoming digit string on DID and tie trunks by inserting (adding) or
absorbing (deleting) digits. You’ll need to do this if the number of digits you receive doesn’t match your
dial plan.
Instructions
As an example, let us say you have a DID trunk group. It’s group number is 5. Your service provider can
only send 4 digits, but your dial plan defines 5-digit extensions beginning with 6:
1
Type change trunk-group 5 and press
ENTER
.
The Trunk Group screen appears.
2
In the Digit Treatment field, type insertion.
This field tells Communication Manager to add digits to the incoming digit string. These digits
are always added at the beginning of the string.
3
In the Digits field, type 6.
For insertion, this field defines the specific digits to insert. Communication Manager will add a
“6” to the front of the digit strings delivered with incoming calls. For example, if the central office
delivers the string “4444,” Avaya Communication Manager will change it to “64444,” an
extension that fits your dial plan.
4
In the Expected Digits field, type 4.
This field tells Communication Manager how many digits the central office sends.
NOTE:
The
Expected Digits
field doesn’t appear on the screen for tie trunk groups.

Press
ENTER
to save your changes.
