Ooma: Setting Quality of Service (QoS)

If you find that the quality of your Ooma phone just isn’t up to snuff, there is a configuration change you can make that may help. This change requires taking a few steps to complete. If you focus on each of these steps, one at a time, this can be a simple process to complete in 5 minutes or less.

Some common problem this may help with is are delay or echo in your voice signal, calls spontaneously dropping during a conversation, poor voice quality in general, and more. Sound like this might help? Then let’s get started…

Step 1: Figure out your data upload speed.

Navigate to the link below and run a speed test. A speed test will give you some measurements of your Internet connection. The two primary numbers in any speed test are your data download speed, and your data upload speed. For the purpose of this test, we are looking for your data upload speed:


Once you run your test, find the upload speed and then discount that number by 15%. You will use this number in the Step 4. (For example, if your upload speed is 10Mbps, times it by .85. The result of this example is 8.5Mbps).


Step 2: Plug your computer into the HOME NETWORK port on the back of your Telo.

You will need an Ethernet cable to plug your computer into your Telo. Once plugged into the HOME NETWORK port, please verify you can access the Internet before going to the next step.


Step 3: Navigate to the Telo Setup page.

Once plugged into the Home Network port on your Telo, go to http://setup.ooma.com to access the Ooma Telo Setup screen. It will look like this:

Now navigate to the Advanced tab to see the screen above, and locate the Quality of Service section of this interface at the top of the page.

Notice that the default Quality of Service configuration of your Telo is 512Kbps. What we’re trying to do in this exercise is to increase this number to reserve more of your outgoing bandwidth for your Telo (this will not affect your Internet download speed).

Step 4: Make a Configuration Change

One more quick math problem to solved before we’re done. We need to express the number you calculated in Step One above in kilobits per second (opposed to megabits per second). Take the number you calculated in Step 1 and times it by 1,000. If we continue with our example above, we would take the 8.5Mbps that we calculated, and times it by 1,000 to get 8,500Kbps.

Enter your final number into the Upstream Internet Speed (Kbps) text box, replacing the default value of 512Kbps, and click the green Update button. Once you see the green status message that reads “Advanced Parameters Updated OK,” you can now unplug from the Home Network port; you are done!
