I have an ooma teleo that I bought about four months ago but am just starting to use regularly. It's set up as follows:
Cable Modem => Airport Extreme => Ooma.
The quality of calls is fine, and my internet connection seems to work fine with Ooma, but
there is a significant delay when making any calls - near or far, cell phones or landlines. The delay is severe enough that we have awkward conversations where each caller is talking over the other. In fact, my wife basically refuses to use it anymore and relies on her cellphone instead.
Here is what I've already tried to solve the problem:
(1) switching the order of the setup, so that ooma comes before the router
(2) switching to openDNS
(3) setting quality of service settings on the Ooma so they match the max speed attained on internet connection speed tests (as per Ooma support advice I found on the internet).
None of these have worked.
Here are my stats from the VOIP speed test website ( http://www.whichvoip.com/voip/speed_test/ppspeed.html ):

Any ideas for resolving this would be greatly appreciated.
Thanks in advance.
Good luck in finding a solution to this. We have the Ooma Telo in our house and the delay is there, but it's not at all to a point where we step all over a conversation and vice versa when using it. My parents' delay is horrendous though.
