    I'm in the midst of troubleshooting a problem with my Airave and Palm Pre. Sprint is telling me that the problem is my Internet provider, Time Warner Cable (Roadrunner), that their network isn't suitable for VOIP.

    If you are happy with your Airave service, would you mind running this test and sharing your results with me? I'd like to see if it's possible to do poorly on this test and yet have a reliable Airave that doesn't keep losing you.

    voiptest.packet8.net/ (You need to press "Click to start test.")

    It takes a minute or two to run all the tests. Jitter is supposed to be < 3ms, but < 5ms is okay. Quality of Service (QOS) is supposed to be 85% or higher. Otherwise the Airave may keep dropping the connection.

    My jitter is 15ms and my QOS varies from 63% to 75%. Jitter and QOS measure packet latency and packet delivery order, as far as I can tell.

    Thanks for your help!

    just ran it. here is what i have:

    As far as Airave goes, it seems to work ok. it has its bad days and good days. Most of the time it works ok i guess.

    My Airave also seems to preform well. I have my router running QoS, with both Vonage and my Airave given high priority.

    Thanks guys. I ran some more tests and am finding that I sometimes get results like those you posted. I tested Clear Wire too and found them getting similar results. Yet both Time Warner and Clear Wire both run VOIP over their connections, suggesting that Sprint was incorrect to put the blame on Time Warner.

    I concluded that the problem might be the Pre itself; I think I figured out why the Palm Pre doesn't always work well with the Airave. I did an experiment comparing the Pre to an old Sanyo phone. The Pre works poorly when the public signal varies a lot. The Sanyo phone does fine. See my post explaining this.

    Comcast HSI, Sprint, Launch Pre, Airave rarely drops calls. Hope this helps.
