Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 317

A recent audit discovered incidents of toll fraud. Restrictions should include Cisco UCM class of service and supplementary services features. Which two actions in Cisco UCM prevent further toll fraud from happening? (Choose two.)

Answer options

• A. Implement a class of restrictions on the gateway.
• B. Implement transformation pattern for all off-net calls.
• C. Set the service parameter to block off-net to off-net transfers.
• D. Restrict international patterns on SIP trunk CSS to the gateway.
• E. Set the call forward all CSS to restrict international patterns.

Correct answer: C, E

Explanation

The correct answers, C and E, effectively limit the potential for toll fraud by blocking off-net to off-net transfers and restricting international calls, which are often exploited in fraud cases. Options A, B, and D do not directly address the main issues related to toll fraud prevention as effectively as C and E do.
