5.6.3. Configuring User Class
User-class setting is used to reject receiving calls from the unauthorized users
when an incoming call arrives in the FXO from the network. When a user
attempts a call to the FXO port through the network while no user-class is set,
the user will have to enter the extension code digit after hearing dial tones
generated by the PBX if the FXO is connected to the internal line of the PBX.
However, if the FXO is connected to the PSTN, the user will hear dial tone
created by the PSTN switching machine and will have to enter the other side
number of the PSTN.
If any user-class is set, the user who makes the first call will hear “beep” sound
instead of the dial tone. If the user enters the password at this time and if the
password is authorized, the user can enter as many numbers as max-digits
defined in the user-class. (“Beep” sound may not occur due to the gateway
