Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 160

An engineer is implementing toll fraud prevention for incoming calls cluster-wide on Cisco UCM. What is the first step to configure this feature?

Answer options

• A. Set service parameter ג€System Remote Access Blocked Numbersג€ to True.
• B. Set service parameter ג€Block OffNet To OffNet Transferג€ to True.
• C. Set service parameter ג€Block OffNet To OffNet Transferג€ to False.
• D. Configure blocking for inbound calls based on caller ID.

Correct answer: B

Explanation

The correct answer is B because enabling the 'Block OffNet To OffNet Transfer' parameter is essential to prevent toll fraud during incoming calls. Options A and C do not directly relate to preventing toll fraud for incoming calls, and option D, while relevant to call blocking, is not the first configuration step required for this specific feature.
