What is the maximum one-way packet loss and jitter for voice before quality issues arise?

The correct answer is B. < 1 percent packet loss and < 30 ms jitter. Voice calls, either one-to-one or on a conference connection capability, require the following: ≤ 150 ms of one-way latency from mouth to ear (per the ITU G.114 standard) / ≤ 30 ms jitter / ≤ 1 percent packet loss.
