A Feature Access Code (FAC) must contain from one to four characters. These characters can be digits or a combination of digits and a character such as an asterisk (*) or a pound sign (#). If you use a character, you must position this character first in the FAC.
The asterisk (*) and pound sign (#) characters are often used in pairs. You can use one of these characters and digits to activate a feature and the other character and the same digits to deactivate the feature. For example, if you use the asterisk (*) and the digits 2 and 9 to activate the Posted Messages feature, then you can use the pound sign (#) character and the digits 2 and 9 to deactivate the Posted Messages feature.
Note:
Users with analog rotary telephones cannot dial FACs that contain an asterisk (*) or a pound sign (#).
You can use the following types of FACs:
  • Access FACs: To gain access to a feature.
  • Activate or deactivate FACs: To activate or deactivate a feature.
  • Send or Cancel FACs: To send or cancel a message.
  • Lock or unlock FACs: To lock or unlock the message retrieval capability of a telephone.
Many features have default FACs that you can change.
An FAC must be unique and must conform to the dial plan. If you define an FAC that is assigned to another feature, the system displays an error message.
Note:
If a feature such as Call Forwarding, Send All Calls, EC500, or Limit Number of Concurrent Calls is activated or deactivated on a deskphone by using an FAC, but the corresponding feature button is not administered on the deskphone, an indication of feature activation or deactivation is not provided to the user. Therefore, Avaya recommends assigning a feature button to the deskphone of the user who intends to use the feature.
