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

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:

This field tells Communication Manager to add digits to the incoming digit string. These digits
are always added at the beginning of the string.

In the Digits
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.
