Examples:
Example 1: Internal calls only
This filter prevents the respective users from dialling call numbers beginning with an 0. The
user can therefore only make internal calls if an 0 is defined as exchange access code in
your telephone system
Example 2: Internal calls with exceptions
In Example 1 the filter also prevents the users from calling emergency numbers such as
those for the police or ambulances. That is why exceptions can be specified as in Example
2.
Example 3: Only domestic calls (Germany) including Austria & Switzerland
In this example it is not possible for the configured users to make international calls,
except for calls to Austria and Switzerland. The exchange access code has not yet been
taken into account here to allow this filter to be used within a further filter in Example 4.
Example 4: Domestic calls (Germany) including call-by-call providers
The “national” filter from Example 3 is used here. The “national” filter is used after the
exchange access code in the first entry. The second entry has been made to also prevent
international calls from being made via call-by-call providers. The two full stops (periods)
are used as place holders for the dialling codes of the various providers. The “national”
filter is only used after the four-digit dialling code.
Example 5: Recursive call-up of the filter
The filter should also take effect within a network of several PBX Applications if a VoIP
Gateway at a different location is used to access the exchange line. A simple filter is no
