What is the maximum amount of packet loss an engineer should allow for voice traffic on an IP network?
Agree, 1% is correct
Definitely wrong. This goes back to the earliest of voip days.
QoS Requirements for Voice
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
•17 to 106 kbps of guaranteed priority bandwidth per call (depending on the sampling rate, codec, and Layer 2 overhead)
•150 bps (plus Layer 2 overhead) per phone of guaranteed bandwidth for voice control traffic
wrong the answer is D.
I concur. D is the correct answer.
Mistake here, correct is D, 1% of loss
Less than 1% is the correct answer.
