which is connected with that port, and put desired extension number. (Or
anybody, who tries to call trough network to FXO port, can hear a dial-tone
from PSTN exchanger, which is connected with that port, and put desired PSTN
number.)
If at least one of user-class is configured, initial caller shall listen beep sound
instead of dial tone and after passing password, caller can input numbers as
much as max-digits, which is defined in user-class. So, using max-digit number, it
is possible adjusting of extension call, intown call, local area call, long distance
call, and international call.
One or more user-class can be configured. So, different call limitations are
capable for different user classes.
To keep the security of calls incoming to the FXO port through the network,
users can use this command and “security permit-FXO” command in the
AP2120 Gateway. Since it is possible to directly attempt calls to the PSTN
through this FXO port or indirectly attempt calls to the PSTN through the PBX
internal line, unauthorized remote users can attempt calls as well. To prevent
unauthorized users’ attempting calls, the security shall be kept. Two security
systems that AP1100 provides have following advantages and disadvantages.
With “security permit-FXO” command, remote users does not need to enter the
password so they can easily access the network.
However, IP address of the VoIP peer on the other side shall be registered and
the gatekeeper cannot be used at the same time. Also, it is impossible to bar
calls of the registered peers by class.
With the “voice class user” users need to enter the password digit but stronger
and multi-classed call barring is possible.

mode.
