This is a handy way to restrict incoming or outgoing calls using the BES server. You can be very precise, restricting calls to or from only a certain number, or using a much wider field, such as country code. See the excerpt below from the Blackberry Administration guide for the proper usage to create a firewall based IT Policy for call restrictions.
Firewall policy group
Restrict Incoming Cellular Calls IT policy rule
Description
This rule specifies whether the BlackBerry® device firewall blocks calls that the user receives unless the calls use a set fixed
dialing pattern.
This IT policy rule does not affect emergency calls.
Default setting
Policy Reference Guide Firewall policy group
The default setting is a null value.
Usage
Type one or more fixed dialing patterns (for example, specific dialing numbers, or a set of dialing numbers with the same
prefix) separated by a semi-colon.
To receive calls from numbers preceded by 1 or +1 only, type +1…;1…
To deny receiving calls using a specific pattern, append r to that pattern. For example, type 011…r to deny receiving calls in
the format 011NNNNNNNNNN.
To indicate that all other patterns are denied, type r in the pattern list. For example, to receive calls from the number
519-555-1234 only, type +15195551234;+15195551234;r.
Dependencies

Minimum requirements

- BlackBerry® Device Software Version 4.3
