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.
For more information about the incoming call handling, see the Incoming Call Handling Treatment chapter in the Avaya Aura® Communication Manager Screen Reference.
Procedure
Enter change trunk-group 5.
In the Digit Treatment field, enter 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.
In the Digits field, enter6.
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,Communication Manager will change it to 64444, an extension that fits your dial plan.
In the Expected Digits field, enter 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.
