Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 203

A user in location X dials an extension at location Y. The call travels through a QoS-enabled WAN network, but the user experiences choppy or clipped audio.
What is the cause of this issue?

Answer options

• A. missing Call Admission Control
• B. codec mismatch
• C. ptime mismatch
• D. phone class of service issue

Correct answer: A

Explanation

The correct answer is A, as missing Call Admission Control can lead to insufficient bandwidth being allocated for voice calls, resulting in poor audio quality. The other options, such as codec mismatch or ptime mismatch, typically cause different types of audio issues, but not specifically the choppy or clipped audio associated with bandwidth constraints.
