Implementing Cisco Collaboration Applications (CLICA) — Question 159

Users report that they are unable to check voicemail, and an engineer discovers that the voicemail system is not routing calls between Cisco Unity Connection and Cisco UCM via SCCP. Which action should be taken to resolve this issue?

Answer options

• A. Verify voicemail SIP trunk in the route list.
• B. Verify OPTIONS Ping in the SIP trunk profile.
• C. Verify registration of the CTI ports.
• D. Verify Calling Search Space in the Directory Number setting.

Correct answer: D

Explanation

The correct answer is D because the Calling Search Space determines which numbers a user can call and which calls can reach the voicemail system. If the Calling Search Space is not correctly configured, users may not be able to access voicemail. The other options focus on different aspects of the system and would not directly address the routing issue related to voicemail access.
