Implementing Cisco Collaboration Applications (CLICA) — Question 111

A collaboration engineer wants to stop fraudulent calls to the PSTN that are being made through Cisco Unity Connection. Cisco Unity Connection is integrated with Cisco UCM via the SCCP protocol. Which action accomplishes this goal?

Answer options

• A. Change the configuration of the routing rule.
• B. Change the Rerouting CSS on the trunk to Cisco Unity Connection.
• C. Remove values from the restriction table.
• D. Change the CSS of the voicemail port.

Correct answer: D

Explanation

Changing the CSS of the voicemail port is the correct action because it directly controls the call permissions for the voicemail system. The other options either do not specifically address the issue of fraudulent calls or pertain to configurations that do not effectively restrict access to the PSTN.
