Using the Blackberry Enterprise Server to restrict phone calls

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
