https://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-express/107626-cme-toll-fraud.htmlThe correct answer to the question is B. Implement route patterns in Cisco Unified CM.
Toll fraud is a type of telecommunications fraud that occurs when unauthorized individuals gain access to an organization's telephone system and make long-distance calls at the organization's expense. Toll fraud can be a significant problem for organizations, and it is essential to take steps to prevent it.
Cisco Unified Communications Manager (Unified CM) is a call-processing system that is used to control and manage voice, video, and messaging applications in an organization. Unified CM has several features that can be used to prevent toll fraud, including route patterns.
Route patterns are used to define the dialing rules for outbound calls in Unified CM. By configuring route patterns, an organization can restrict outbound calls to specific numbers and prevent unauthorized long-distance calls. For example, an organization could configure a route pattern that only allows outbound calls to specific area codes or countries.
Implementing toll fraud restriction in the Cisco IOS router (answer A) can be a useful step in preventing toll fraud, but it is not sufficient on its own. The router can be used to block specific types of calls, but it is not as flexible as the route patterns in Unified CM.
Allowing off-net to off-net transfers (answer C) can increase the risk of toll fraud. Off-net to off-net transfers refer to calls that are made between different carriers or service providers. Allowing these types of calls can make it easier for fraudsters to make unauthorized long-distance calls.
Configuring ad hoc conference restriction (answer D) can help prevent toll fraud by restricting who can initiate ad hoc conferences. However, this feature alone is not sufficient to prevent toll fraud, and organizations should also implement other measures, such as route patterns, to prevent unauthorized long-distance calls.
In summary, implementing route patterns in Cisco Unified CM is the most effective way to prevent toll fraud in an organization's telephone system.
