I have recently discovered that whenever I am uploading photos to Picassa my Obi202 becomes unusable-- the call breaks up to the point that I can't be heard by the other party (I can hear them fine). This happens whether I am receiving or placing a call, and on both of my service providers as well as Google voice. Clearly there's an uplink network traffic issue of some kind. I only have this problem when uploading to Picassa-- I regularly back up gigabytes of data to another service, and never have this issue.
I tried enabling QoS on my router once before, using a mac filter to prioritize the Obi, but it didn't appear to work, and it seemed to me that the call quality might have gotten worse. After reading some about the issue, I came across the opinion that we should not enable QoS, so I disabled it. Everything has been fine since, except when I take pictures.
I would really appreciate suggestions from any of the thoughtful VOIP folks who frequent this forum. I'd love to solve this problem once and for all.
