How to alert for possible Toll Fraud

Toll fraud is long-standing issue that impacts many organizations telephony systems.  This illicit use of a telephony system to make calls, not necessarily long distance or international calls, is difficult but not impossible to combat.  In a Cisco VoIP environment you can use CUCM Class of Service, Cisco Native Gateway Toll Fraud Prevention Applications, Gateway Class of Restriction and Unity Connection rules to try and prevent these unauthorized calls, but even beyond these measures you may still be susceptible to calling vulnerabilities.  It’s a good idea to setup CDR alerts to keep you informed of possible toll-fraud.

Within the United States and Canada there are area codes that can be reached without dialing an international code. This is normally where Toll Fraud becomes an issue.
