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.
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 will take around one minute to complete. The results of the test will include measured information for your Internet connection and consist of jitter, upload and download speeds, MOS score and packet loss. Use the "Click to start test" button below to start the VoIP test. Ask questions or add a comment about your results here.
|NOTE: The speed test requires JAVA installed on your device to run. Based on your screen size we have determined that you are using a mobile device. Please visit this page from your laptop or PC to utilize this test. Sorry for any inconvience but JAVA is not typically available on mobile devices.|
If your results show five green circles then your Internet connection will support VoIP. If yu have four green and then a yellow for consistency of service this is usally fine too. If you are not sure how to proceed, then read the following section on definitions to try to understand what your issue might be.
NOTE: If you see the message "We were unable to measure your connection's jitter/packet loss..." then the most likely issue is that a socket test cannot be initiated (it will do a HTTP/POST test instead of a socket test for speed). This can occur if the ports 20000 and 20001 are blocked for UDP packets (either by something in your setup or by your ISP).
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. Also keep in mind that your upload speed will often be significantly less than your download speed. 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.

We hear incoming calls very well. When we speak the other person always tells it is very garbled, hearing 1 out of 3 words. Any suggestions?
-> Response: What results do you see when you run our VoIP test?
This sounds like it may be a bandwidth issue on the uplink direction, which often is lower speed than the downlink direction (i.e. outgoing bandwidth lower than incoming bandwidth).

Why does my voice break up when speaking. I hear others Okay.
-> Response: When this happens it normally means you have either low bandwidth on your uplink Internet link or inconsistency of service (or extensive jitter on uplink).
Do you have a decent Internet service? What results did you get when running our VoIP test?

Can you please tell us where is your server location? Any way I can force a destination to the Voip Test?
-> Response: This server is in Los Angeles, California. Unfortunately there is no way to change this location, as it runs on a dedicated server in Southern California.
