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.

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.

  1. I have to admit that the quality of my SkypeOut and even Skype2Skype calls is not always good.
    It is cheap however!
    Yesterday i had a "one hour" Skype2Skype call to Brazil: i stopped like 4 times the conversation, and called again. The quality was really fluctuating.
    Some days ago, "same call": 1 hour without any problems!
    Don't forget the "bad study" was about what interests us more: Skype and similar PC 2 PC VoIP!

  2. There is an interesting thread where it is explained in the Skype Forums.
