Use the free VoIP speed test and Bandwidth test analysis tool below to check your Internet speed and to see whether VoIP would be a good option for you. This tool analyses your broadband internet connection for the key components required for allowing good quality VoIP phone calls. The voice quality of a phone call using VoIP depends on four main connection properties known as Bandwidth, Delay, Packet loss and Jitter (for those who want to know more about these technical terms see descriptions below). These four properties are analyzed and summarized at the end of the test. Use the "Click to start test" button below to start the VoIP speed test. If you are experience problems seeing the tool below or when running it, please download the latest version of Java. This tool performs all the tests you need to check out your high speed internet connection, whether you just want to verify your download or upload speeds, or whether you are checking your connection to verify it is sufficient for quality VoIP phone service.
This test should take less than one minute to complete and you will then be presented with a short summary of download and upload speeds, jitter, packet loss and MOS score. Hit the button below to start the VoIP test. Ask questions or add a comment about your results here.
If your results show four green circles then your Internet connection will support VoIP. If you are not sure how to proceed, then read the following section on definitions to try to understand what your issue might be.
Bandwidth - This is a popular term and you have likely had your Internet provider try to up sell you to a higher "bandwidth" that will give you faster speeds for uploads and downloads to and from the Internet. This is typical displayed in Mbps (Mega bits per second) or Kbps (Kilo bits per second) with home Internet download speeds typically ranging from 3Mbps all the way up to 50Mpbs. it really depends on your needs and how much you are willing to pay every month. Your upload speed will typically be much less than your download speed and can often be up to one tenth less. The good news is that for VoIP you only need around 90kbps worth of bandwidth so if you have a regular high speed connection such as DSL or cable, you should be in good shape.
Delay - If your delay is less than 100 milliseconds, your voice calls should consistently be of high quality. Even delays up to 400 milliseconds (as per ITU) can result in decent call quality.
Packet Loss - Any packet loss up to 5% will likely not be noticed by you when you are making calls. As these are digital packets it is often possible to have a packet loss of 0%.
Jitter - This is measured in milliseconds and is created by some instability in your connection. It is a fluctuation in the signal such that it becomes out of sync or displaced from where it should be in the transmission. It is effectively a continuous variation in the delay of packet delivery. VoIP jitter can be tolerated up to 20ms to 30 ms.
MOS Score - MOS stands for Mean Opinion Score and is actually a score given by a human user when evaluating the quality of voice. As it is an opinion, it is subjective. A MOS score of 4.0 or higher is desired.
Even if you VoIP speed test results are good, you may still run into issues at some point with your voice calls. This can be due to a number of different reasons but is often caused by your internal network not being configured to prioritize the voice packets over all other packets. For example, if you are streaming video while someone else in the household is uploading some pictures to a cloud application, your bandwidth may be consumed by this video and data traffic, leaving very little room for your voice calls to get through. Think of your Internet connection as a pipe and only so much can fit through that pipe at one time. The way around this is to enable Quality of Service (QoS) on a home network router or telephone adapter, and set it to prioritize voice traffic to the Internet. This effectively reserves some room in your pipe such that you will always have room for your phone calls.

Don't jump to conclusions and blame your VoIP provider for poor quality of calls as it may actually be an issue with your own home network.

I have had Ooma telo for several months, with pretty good quality. But of late it's been very poor - voices garbled and calls sometimes dropped. I just did your tests and I had all green lights except on jitters which is 38.0 ms and my score was 1.0 which I know is also bad. Is there any way I can improve this? Why was my Ooma working ok initially? Any help would be very appreciated.
-> Response: Did anything else change in your setup such as your Internet Service Provider? Also did you change any hardware in your home network such as your router? Was the jitter in both directions or just one?
Posted by Ron Oswald on November 8th, 2013:
I am assuming that the term downstream jitter/packet loss is referring to my computer and the upstream jitter/Packet loss is the network is this correct or do I have it backwards??
-> Response: Downstream is from our servers to your computer and upstream is from your computer to our servers on the Internet.

Unfortunately, the test requires Flash, which I have disabled for security reasons. Bummer. My advice? Make a test that doesn't require flash.
-> Response: George, it runs on Java - did you download the latest version of Java?

I have satellite Internet with Hughes and the results from this test are not very good, especially for jitter and the mos score.
-> Response: Jim we moved your full comments over to our satellite page and sent you an email to get a snapshot of your results.

MOS score is 1.8. I have HughesNet Gen4. Using basictalk voip and have significant voice delays & sound breakups - any suggestions? Wife is not happy! Cable/DSL is not available at my home and cell service is also out of the question (only reliable 1 bar signal is on my neighbor's deck). Please HELP!!
-> Response: We usually do not see much success with VoIP over a satellite Internet connection we are sorry to say Bruce. HughesNet Gen4 does indicate it can support Skype/VoIP so it may be worth looking at your setup first.

In review of my results (which indicate good voip connectivity), I have fixed wireless (microwave) provider. Do you think I would be successful with a unit such as Ooma. Do you have other provider recommendations.
-> Response: Gin, if the results are good then you should be fine with any provider. Start by taking a look at our residential home page (tab at top). From there you can find articles, user reviews and more for lots of providers including Ooma, MJ, Vonage etc. It really depends on your requirements as to which provider to go for, for example, do you need to make International calls, do you need a feature rich service, incoming fax etc. If you are driven by price only then take a look at our price tool.

Just ran your test on my VONAGE setup. Score was 4.1. Can't complain about the excellent service I've received from VONAGE since 2007. No contract, free LD, etc. for $21 per month. Think I'll keep it! Elizabeth
-> Response: Hi Elizabeth, glad VoIP is working out for you. Please keep in mind that the test is really testing your Internet connection not your VoIP provider. It is a great test to ensure your Internet is good enough for VoIP. 4.1 is a really good score so you must have a decent broadband connection.

How do I print the results from the VoIP test?
-> Response: There are two ways Gary, first just do a print screen to capture an image from the screen or even just print from your browser. If you want to grab the info in text format, when the test finishes and the summary is shown, click on the "Test audit report" link. You will then have a lot of test data you can copy and paste or print. Also in that screen you can then click on "Analyze this test" to get some more data such as the MOS score and jitter that you can print or copy/paste.

After running the test (which is great), I select the 'View Text' and get a popup with all the pertinent data. Why can this popup data not be copied onto my clipboard for subsequent pasting?
-> Response: Good feedback. There is actually a way to get it. Once the summary is displayed click on the "test audit report" link. On the summary that appears click on the "analyze this test" link. Now you are presented with the important VoIP test summary info for packet loss, MOS, jitter etc and can copy and paste this.

What does MOS Score mean? Mine was estimated to be 4.2. Is that good or bad?
-> Response: Cheryl MOS stands for Mean Opinion Score. It is a telephony measurement that is meant to show a human view of the quality of a given network. 1.0 would be bad, 3.0 would be fair and 5.0 would be excellent. 4.2 is very good so I would say you were in good shape. Good question.

Where is Vonage in your service providers?
-> Response: We used to have them in our table but they tend to be a lot more expensive than the providers you currently see so were not a popular choice. They are still in our site though and we have articles on them and user reviews.
