The jitter I just measured on a Sunday afternoon is repeatedly less than 5 ms, download speed above 10 mbits and upload greater than 2 mbits. So what? On Tuesday evening when my wife needs to make a call at 4:30 PM it's unusable cause the jitter is 50 to 250 ms.
There's no issue with my modem, nor with my cables or splitters. Technicians have been out to my house twice. I can access the modem details and the signal quality and SNR are fine.

The Ooma technical support says the problem is jitter. I had him on the line with me and we measured download rates exceeding 10 mbits/sec and uploades exceeding 2 mbits/sec. However the jitter as measured by pingtest.net was all over the place.
So, Comcast's voip works fine but Ooma doesn't. If it was simply bandwidth, how does Comcast guarantee performance? And of course my next question is why can't they do it when I use Ooma?
