Call a Divorce Attorney.


We all know you meant the lag issue but the sentence makes it look as if your wife's complaining is THE issue.


Maybe you can call the Dr Phil show and see if you can get on that, That will be a good thing before the lag gets really ugly, dont want to see it get so bad it turns into a Jerry Springer call.


In all seriousness...

Go to setup.ooma.com and click on the status to the left and see what REV of the firmware you are running, make sure you have the latest firmware, which is 36111.

What download/upload speed do you subscribe to with your DSL? Do you have anything that connects to your network constant, a P2P program, or online backup? Online backups can cause problems. If you have an online backup,change it to low priority mode.

Other than that, you have 2% packet loss, I would wonder why your losing packets. Try a new phone cord, a shorter one if you can. I know with me, I had a lot of problems at first, and I have a cable modem, and my cables were a little loose and that was causing problems. How long have you had DSL? And the modem? If its been a few years, maybe try switching out your modem with your provider if you can.

Dropped packets will certainly cause more delay. In the USA we're not supposed to have any packet loss these days.

Bottom line is that without a good clean internet connection with no packet loss, you're going to have issues with delay. The iLBC codec at least allows you to carry on with loss but there will be more delay. The g.711 codec "fax mode" is even less tolerant to loss.

I'm also having a serious lag.

QOS 96%
Upload QOS 98%
RT time 64ms
Max delay 44ms
Jitter .5ms
Packet loss 0


Ooma Settings-Before the router
Upstream Internet Speed (kbps) 768
Downstream Internet Speed (kbps): 80000 (I've also tried zero)


I really don't know how I could get better numbers than this. Why the delay? Is this just normal?

I can have 2 cell phones in my and they are instant. When I do the same test using Ooma and a cell phone there is like a 1-2 second delay.









Why the delay.

Find out why it is reporting these two marginal results and you will nail it.

A delay of 1-2 seconds is a really long delay, quite a few words difference. If testing between a cell phone in your home and Ooma, you will normally hear a describable delay (small fraction of a second) but it should not be enough to be an issue when making a real-world call where you can't hear the spoken voice both through the air and over the phone. If the delay really is a full second or more then you very likely have some Internet connection issues.

I just got off the phone and there is defenitly a delay. It was painful to even talk to the person. The call quality seemed fine but the lag was terrible.

Your Speed and Voip test results are excellent. I would look for another possibility.
