VoIP Call MOS Audio
The estimated Mean Opinion Score (MOS), as determined by the E-model, has exceeded or (more typically) fallen below threshold.
Some possible reasons for this event:
♦Network congestion is causing delay, jitter, and resulting in packet loss and hence poor voice quality.
♦Link failure is causing packet loss and resulting in poor voice quality.
♦Route flapping is causing jitter and resulting in packet loss and poor voice quality.
♦Ethernet problems along the voice path (such as bad cables or interfaces) are causing packet loss and poor voice quality.
