My Dad uses the bare bones slowest ATT DSL w/ OOMA and has no troubles ever. I've got the fastest Time Warner of 18M/2M and get mediorce service at best.
Tried adjusting the QOS bit by bit both lower and higher, using the 80% rule, using the closest to the upload speed rule, and nothing works. I even dial *99 and it still stinks. All cables are new and speed test look good. My only guess is high jitter on cable networks.
Next week I get Uverse installed ( lucky for me it is available in my area in Austin ).
Anyone have bad results with Time Warner and good results with Uverse they can talk about?
Nope. Just good results with Time Warner and Ooma in my area (L.A.). Haven't had any problems. Just signed my Mom up with the same set up. No problems at all so far.johnnyrod wrote:Anyone have bad results with Time Warner and good results with Uverse they can talk about?
If you have your Ooma hub AFTER the router, then adjusting the QOS on the Ooma hub will do nothing. Because it only shapes traffic coming into the Ooma hub.
If it is AFTER the router, then you have to adjust the QOS within the router. If you have an old router that doesn't have QOS functionality, then flash it with DD-WRT firmware and use that for QOS functionality.
Comcast cable is another story. They know what the problem is but unwilling to fix[spend money to replace the out side line] Even regular tv is unwatchable with static all over.
As others have asked, we need to know a bit about your situation.
What router and firmware are you using to establish your QoS? I just recently determined the firmware I was using has problems with QoS. I switched to different firmware and the QoS works perfectly.
Stick with us for a bit to see if we can help resolve your problem.
When you get a chance can you try http://www.whichvoip.com/voip/speed_test/ppspeed.html and post your results.
Theren is a basic difference between cable service and DSL....My Dad uses the bare bones slowest ATT DSL w/ OOMA and has no troubles ever. I've got the fastest Time Warner of 18M/2M and get mediorce service at best....
DSL is a "home run link" between your location and the DSLAM in the CO.
You get consistant bandwidth / performance)
With cable, you are sharing available bandwidth with everyone else in your area (up to 256 others). Your speed / performance varies if others in the neighborhood are all on line at the same time doing various bandwith intensive tasks
Try making some test calls very early in the morning - 3 or 4 AM when there is less expectation of many others being awake and see if your call quality improves
Cable Modem - Ooma - Router. The router is a Linysys WRT54GS w/ firmware 7.2.06.
I tried to call Canada yesterday and no one could hear me on the other end. I called Singapore today and can't connect. I called CA yesterday with lots of echo and I call locally in Texas with slightly garbled voice.
I had TW come in a few months ago to check the connection and they said it was good and even gave me a new modem. It worked for a month or so and then it was back to crappy service again.
At 8:45AM on a Saturday morning here is my VOIP results.

I think putting your Ooma before your router will be an excellent test. If that works successfully, there are some things we can do to help you get your router's QoS up to snuff.
My first call with Ooma was walkie talkie like and there was an echo. I switched it to Cable Modem > Router > Ooma and my troubles instantly improved to perfect sound quality and a very minor walkie talkie effect, which I can live with. Way better than my cell phone .johnnyrod wrote:Cable Modem - Ooma - Router.
