If you try to enter a code that is assigned to a feature, the system warns you of the duplicate code and you cannot proceed until you change one of them.
Tip:
To remove an FAC, delete the existing FAC and leave the field blank.
For example, to change the FAC for Call Park to *72, perform the following procedure:
Procedure
Go to the administration interface.
Enter change feature-access-codes.
Press Enter
The system displays the Feature Access Code (FAC) screen.
On the Feature Access Code (FAC) screen, type the new code *72 over the old field in the Call Park Access Code field.
