Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 178

Which two recommendations are made to optimize Cisco UCM configuration to reduce the number of toll fraud incidents in an organization? (Choose two.)

Answer options

• A. Classify all route patterns as on-net and prohibit on-net to on-net call transfers in Cisco UCM service parameters.
• B. Classify all route patterns as off-net and prohibit off-net to off-net call transfers in Cisco UCM service parameters.
• C. Classify all route patterns as on-net or off-net and prohibit off-net to off-net call transfers in Cisco UCM service parameters.
• D. Inbound CSS on any gateway typically should have access to internal destinations and PSTN destinations.
• E. Inbound CSS on any gateway typically should have access to internal destinations only and not PSTN destinations.

Correct answer: C, E

Explanation

The correct answer involves classifying route patterns appropriately to prevent unauthorized off-net calls, which is crucial in combating toll fraud. Option C ensures that off-net to off-net transfers are restricted, while option E limits access to only internal destinations, thus enhancing security. Options A and B do not effectively address the issues related to off-net transfers, and option D opens up vulnerabilities by allowing access to PSTN destinations.
