What jitter is acceptable for VoIP?

ITU-T G.114 recommends one-way delay < 150 ms and jitter < 30 ms for acceptable VoIP quality. Above 50 ms jitter requires large buffers that increase perceived latency, degrading conversation quality.

How is jitter measured?

Jitter is the standard deviation or mean absolute deviation of one-way packet delay. It can be measured with tools like iperf3, Wireshark, or TWAMP. RTCP sender reports include jitter estimates in RTP streams.
