How Good Is VoIP Call Quality? It Depends On Who You Ask
Does VoIP offer better, equal or poorer quality than traditional phone service? It definitely depends on who you ask.
Two surveys provide very different views of VoIP service acceptance. The earlier study, commissioned by Brix Networks, concluded that almost 20 percent of all VoIP calls made during the past 18 months were deemed to be unacceptably poor. Moreover, during that time the quality of VoIP calls got continually worse.
The other survey found essentially the opposite. Commissioned by VoIP test equipment vendor Minacom, the study found that the mean opinion score (MOS) of VoIP calls has risen from 3.9 to 4.2 during the past year. MOS is a standard telephone companies use to measure perceived call quality.
