Inserting And Absorbing Digits - Avaya Communication Manager Administrator's Manual

Managing Trunks

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. Press Enter.
The Trunk Group screen - page 1
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 does not appear on the screen for tie trunk groups.
Note:
5. Press Enter to save your changes.
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. Press Enter.
The Trunk Group screen - page 1
2. In the Digit Treatment field, type absorption.
This field tells Communication Manager to remove digits from the incoming digit string.
These digits are always removed from the beginning of the string.
