Analyze voice quality (MOS) impact based on network jitter and packet loss using the ITU E-Model approach.
Awaiting Network Telemetry
Network jitter (variance in delay) causes packets to arrive out of order or too late to be played. VoIP terminals use a Jitter Buffer to store packets and smooth out the stream, but this adds end-to-end delay. The E-Model (G.107) quantifies these impairments into a Mean Opinion Score (MOS) from 1 to 4.5.
Most modern VoIP clients adjust the buffer size dynamically based on measured network jitter.
Packet Loss Concealment. Uses interpolation of audio from previous frames to fill gaps caused by lost packets.
Mean Opinion Score. 4.0-4.5 is high quality, 3.5-4.0 is fair (mobile grade), below 3.0 is poor.
