Where possible, when an authorization code is required, the user can enter it through their phones display. However, this is not possible for all type of phone, for example it is not possible with analog phones and Avaya XX01 or XX02 phones. The users of these device must either enter the authorization code using a short code set to the Set Authorization Code feature immediately before making the call.

When entry of an authorization code is triggered, the user can enter any authorization code with which they are directly associated.

Note the following.

• If authorization code entry is setup for a particular number, calls forwarded or transferred to that number will also trigger authorization code entry.

• On systems using line appearances to BRI trunk channels to make outgoing calls, authorization code entry may not be triggered. This can be resolved by adding a short code such as [9]XN;/Dial/XN/0 (adjust the prefix and line group as necessary).
