You would really need to do some more extensive network analysis between multiple endpoints to see what the call quality is, and where the problems lie. I have seen great results for speedtest.net in the past, even to the hosting provider, but things fell apart once I started routing real data because the ISPs in between had intermittent routing problems and bottlenecks that showed up over the longer term of a class session or something like that, which wasn't caught by a shorter speed test.
