11.3 Filter – Assign User Rights
In the PBX Application it is possible to assign different users rights for calling. In this way
certain users are prevented from calling, for example, international numbers or numbers
beginning with 0190.
Access to the configuration of the PBX Application is protected by user names and
passwords. The passwords are transmitted via a H.323 connection of the H.235 security
and encryption standard, and are therefore adequately protected against unauthorised
access. The level of security can be further increased by activating an IP address filter to
prevent unauthorised access to the PBX Application. The filter is activated if an attempt is
made to access the PBX Application without a password.
