Quality of VoiceDetermining factors•Jitter

If packets arrive with lots of jitter, delay can be increased

•Packet LossMore than 10 % packet loss is noticeable.

•Latency A delay of over 100 ms is noticeable.

•CODEC More compression usually offers lower quality of voice

•Network Factors More utilization usually means more collisions

Tunable factors•Adaptive echo

cancellation•Tone detection and

generation•Voice activity detection•Silence suppression•Forward error correction•Tunable latency•Dynamic jitter buffer•Bad frame interpolation •Less bandwidth

utilization•Network priority
