A. B. C. D.D.
Toll fraud is a type of fraud that occurs when an unauthorized user gains access to a company's phone system and places long-distance calls, resulting in high phone bills for the organization. Cisco Unified Communications Manager (CUCM) provides several features to prevent toll fraud, including call policy service, TOLLFRAUD_APP, default zone access rules, and class of service.
A. Call policy service is a feature of CUCM that enables administrators to define policies for call routing and dialing. It allows administrators to create rules to restrict access to certain destinations based on specific criteria, such as time of day or user groups. Call policy service can be used to block calls to known fraudulent numbers or restrict access to long-distance destinations.
B. TOLLFRAUD_APP is a pre-installed application on CUCM that provides real-time monitoring and alerting for potential toll fraud. The application monitors call patterns and detects unusual activity, such as a sudden increase in long-distance calls or calls to unfamiliar destinations. It can also generate alerts and notifications to administrators, allowing them to take immediate action to prevent further fraud.
C. Default zone access rules are a set of rules that control access to destinations based on their location. CUCM automatically assigns a default access rule to each destination based on its geographic location. Administrators can modify these rules to block or allow access to specific destinations based on their needs.
D. Class of service (CoS) is a feature that enables administrators to define access privileges for users based on their role or job function. CoS can be used to restrict access to long-distance destinations or block specific types of calls, such as international calls or calls to premium-rate numbers.
In summary, all of the methods listed above can be used to prevent toll fraud in CUCM. Call policy service, TOLLFRAUD_APP, default zone access rules, and class of service all work together to provide comprehensive protection against toll fraud.
