Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 117

Some users report poor quality when they travel to another continent and make calls. This issue applies only to one continent and not to others, where typically the dialing is fast and quality is clear. Users experience the same result at home when they call the same numbers in that specific continent. It seems like some users do not exist in the correct PSTN gateway when making calls to a specific country. The company is using TEHO to save on the cost of international or long-distance calling.

They are also using a globalized dial plan. What is the cause of the issue?

Answer options

• A. CUBE is not configured for TEHO in the specific country.
• B. A local route group is not added to the route pattern.
• C. The users are missing this specific gateway at the device pool level.
• D. Regions in Cisco UCM are not configured correctly.

Correct answer: D

Explanation

The correct answer is D because improper configuration of regions in Cisco UCM can lead to issues with call quality and routing for specific countries. Options A, B, and C may relate to routing issues, but they do not specifically address the region configuration that affects call quality for users in that continent.
