I have Time Warner Cable internet, a pretty fast connection. I am getting horrible quality when I try to use OOMA. I really want it to work, but right now it isn't. I don't know anything about VoIP stuff, so I was hoping someone could look at my test results and help me narrow down why this sucks so much. Hopefully it is something I can get fixed.

Could you describe what kind of problem you are having and how you have your hub connected? The download quality of service number is really low, but this may be caused by how the hub is connected and the QoS settings you are using.

The Download QoS could also be an ISP issue, if restarting all of your networking equipment (ooma hub, router, modem etc.) does not work, call TWC and get a tech out to your house.

Do you know how to access the status page for you Cable Modem? There are some detailed stats that could be useful to determine if you're having Cable Modem issues, or networking related issues.

If you don't mind, could you connect just one computer directly to the cable modem, turn off all anti-virus software, and rerun the test? I want to isolate if your problem is with your cable ISP service, or something else within your network at home.

Cheers,
Scott

All of those numbers look excellent except these:
Download quality of service: 24 %
Upload quality of service: 60 %

Which if that's not an issue with your network then it is with your ISP.

I agree with scoutconnor, I would contact TW and have them check out your connection. Make sure you mention the QOS issues because they're likely to have you run a speed test and claim everything is ok.

Both speed and latency seem to be fine and speed (bandwidth) wouldn't be an issue with VOIP/Ooma.

In addition, you can take a look at these Ooma articles:
http://cp-ooma.talismaonline.com/articl ... 32&p=12040

http://cp-ooma.talismaonline.com/articl ... 02&p=12040

You could try entering these values into the Advanced Settings page on http://setup.ooma.com

Quality Of Service (?)
Upstream Internet Speed (Kbps): 15000 (0 to disable)
Downstream Internet Speed (Kbps): 1000 (0 to disable)

Try that and see if it makes a difference.

Don't you mean Download Internet Speed 15000 kbps

Upstream Internet Speed 1000 kbps?

Just double checking! :)

Since it doesn't appear to be an issue with your ISP (keep your test results handy), give ooma support a call tomorrow and see what they can do for you. There have been others that have had issues and were able to have ooma work their magic with a simple phone call.

Perhaps I am talking to the wrong person. I have talked to support 2x and they just keep telling me that once my number is ported over it will fix everything. But frankly, that makes no sense to me. I don't understand why calling over the internet would be effected by my phone service. It happens on both incoming and outgoing calls.
