Configuring Restriction Tables
Table 18-7 illustrates a restriction table that permits one number in an area code but restricts all other
numbers in that area code.
Following are the parameters that you can configure for restriction tables:
• min-digits — Minimum number of digits for a specified restriction table. Valid values for the
minimum number of digits are 1 to 30. The default is 1.
• max-digits — Maximum number of digits for a specified restriction table. Valid values for the
maximum number of digits are 1 to 30. The default is 1.
• preference — Order of this string in the restriction table. The system searches the strings in order
of preference, starting with 1. Valid values are 1 to 10.
• pattern — Call pattern to be matched. Valid characters are digits 0 to 9, asterisk (*), or dot (.). The
table accepts duplicate call patterns.
• allowed — Permits phone numbers with this pattern to be assigned to message notification devices.
• disallowed — Prevents phone numbers with this pattern from being assigned to message
notification devices.
• insert — Inserts the dial string in the proper place in the table.
Toll Fraud Prevention
When a Cisco router platform is installed with a voice-capable Cisco IOS software image, appropriate
features must be enabled on the platform to prevent potential toll fraud exploitation by unauthorized
users. Deploy these features on all Cisco router Unified Communications applications that process voice
calls, such as Cisco Unified Communications Manager Express (CME), Cisco Survivable Remote Site
Telephony (SRST), Cisco Unified Border Element (UBE), Cisco IOS-based router and standalone
analog and digital PBX and public-switched telephone network (PSTN) gateways, and Cisco
contact-center VoiceXML gateways. These features include, but are not limited to, the following:
