🎙️ Measuring MOS Using Packet Capture & Linux Tools | The Easy Way! 🚀

Mean Opinion Score (MOS) is a key metric for assessing VoIP call quality. It ranges from 1 (bad) to 5 (excellent) and considers factors like latency, jitter, and packet loss. A great MOS score ensures crystal-clear audio and happy users! 😊

To accurately measure MOS, you can use packet captures or powerful Linux tools. These methods help pinpoint network issues affecting voice quality. Even better? 🏆 You can combine them with Nepean Networks' SD-WAN for next-level voice quality validation! 🎯✨
