Sample answer
“To troubleshoot a VoIP call quality issue, I would first collect feedback from users to understand the symptoms. Then, I would use tools like Wireshark to monitor the network. I’d check for high latency or packet loss, and assess the bandwidth usage to ensure it meets VoIP requirements. After identifying the problem, whether it’s a network bottleneck or a misconfigured router, I’d implement a solution and document the steps taken for future reference.”
