In the field next to the specific feature to which you want to assign the FAC, type a FAC that conforms to your dial plan.
You might have to scroll through several pages of the Feature Access Code (FAC) screen to find the telephone feature that you want.
Some features require more than one FAC. Type a FAC in each required field. For example, type a separate FAC in the Call Forwarding Activation Busy/DA field, the All field, and the Deactivation field.
Press Enter to save your changes.
Ensure that you notify all users about the assigned FACs.
