PIN Barring
PIN Barring feature allows to assign and manage credits on the PIN codes configured in the QX Local AAA table. The assigned credits will be spent if the authentication by PIN option is used when making calls through call routing rules with Call Rate Settings enabled.

This can be done by simply highlighting the number you wish to dial and pressing a predefined hotkey sequence (e.g. Ctrl-Y).

System Security Software

These notifications can be generated and viewed in the System Events, sent via email or SMS, or left as a voice message on predefined extension(s) along with a recorded message.
 Securing Call Routing
The Local AAA Table serves as the hub for configuring and managing the local authentication database. When the Local Authentication option is enabled on the routing pattern, the caller needs to pass authorization. This can occur automatically through trusted caller ID detection, manually by entering specific login details (username and password), or by using a handset PIN code. Additionally, you have the flexibility to set an expiration period for the authentication process. Once successfully authenticated, the caller gains access to utilize the designated call routing rule.
PIN Barring
The PIN barring feature enables the assignment and management of credits for PIN codes, which are used when the authentication by PIN option is used for calls made through call routing rules with enabled Call Rate Settings. PIN codes without assigned credits cannot use routing rules with Call Rate Settings enabled.
Similar to the method used for QX extensions, the PIN barring feature calculates call costs per minute and second. Once the assigned credits are exhausted, new calls through toll routing rules become impossible until the credit balance is updated manually or automatically. Users can opt for convenient automatic credit balance updates daily, weekly, or monthly.
