Test Your Internet Connection

Start by running the 8x8 VoIP test. This test simulates 8x8 VoIP calls being made over your Internet connection, and gives you an indication of the level of service you can expect from your 8x8 system, based on your current Internet connection bandwidth and performance. If your current router supports Quality of Service (QoS) and is enabled, please disable QoS prior to starting the test.

Note: The VoIP test requires Java to run.

  1. To begin the test, go to
  2. Enter your parameters for the number of VoIP lines, the test duration, and the codec type.
  3. Select Apply and Test. The test should only take a few minutes.
  4. For the steps on running the 8x8 VoIP test, refer to What is a VoIP Test and how do I run it?
  5. Once the test is completed, click the Summary tab to view your Connection Summary.

    The Connection Summary gives you the following information:
    download speedDetermines if your Internet download speed can support a high-quality VoIP conversation. Insufficient download speed impacts your inbound traffic, including your ability to hear callers.
    upload speedDetermines if your Internet upload speed can support a high-quality VoIP conversation. Insufficient upload speed impacts your outbound traffic, including the ability of callers to hear you.
    Quality of ServiceMeasures fluctuation in your Internet speed. A high QoS percentage is desirable.
    jitterMeasures the constant flow of data. A lower jitter value shows a more consistent flow.
    packet lossMeasures your Internet connectivity and how accurately it is transferring data. Zero percent packet loss is desired for a high-quality VoIP connection.
  6. After examining the results, click the Advanced tab.
  7. Check next to Number of VoIP lines supported to see an estimate of the number of simultaneous calls that your network can support.

    If the VoIP test returns any yellow or red lights, you may experience call QoS issues. Possible solutions include increasing your Internet bandwidth, or upgrading or installing LAN equipment (such as a properly-configured router and/or modem).
