security systems that the AP2120 Gateway provides have following advantages
and disadvantages.

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

by class.
With the “voice class user” users need to enter the password digit but stronger
and multi-classed call barring is possible.
