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
