Why is latency important?
There are two reasons to consider latency: • Latency adds delay to voice communication. If the latency is small enough, neither party will notice the resulting delay; but latency above a certain point will cause a noticeable delay that can be annoying. Even longer latency times can make an IP conversation difficult; each party must wait to take turns talking to avoid “talking over” each other. • High latency (i.e., times greater than 250 ms) often indicates a poor IP connection. Be sure to retest the link during high-traffic times if all the test parameters except latency appear to be satisfactory.
