Implementing Cisco Collaboration Devices (CICD, legacy) — Question 38

An engineer is troubleshooting call quality issues between two sites. On an active voice call, the call statistics on the IP phone show that the max jitter is 100 ms.
What is the maximum amount of jitter that the engineer can allow and still expect to maintain a high-quality audio call?

Answer options

• A. 5 ms
• B. 10 ms
• C. 30 ms
• D. 50 ms C

Correct answer:

Explanation

To ensure high-quality audio, the maximum jitter should be kept low. Generally, jitter levels above 30 ms can start to degrade call quality, making the correct answer 30 ms. Options A (5 ms) and B (10 ms) are too restrictive, while D (50 ms) exceeds the acceptable limit for clear audio.
