One Talk - Use the Site Qualification and Validation Tool

Here's how to use the Site Qualification and Validation Tool to determine whether your network can support One Talk service.
  • Verizon's One Talk Site Qualification Tool allows you to perform a series of tests to help you determine the readiness of your business location, prior to or after the installation of One Talk devices.
  • The tool doesn't store any customer info of any kind, and doesn't store any historical test info for any user.
  • The tool can only be accessed through a desktop browser on either a Windows® PC or a Mac®, and supports the following browsers:
    • Google™ Chrome™
    • Mozilla® Firefox®
    • Safari®
    • Microsoft® Edge
  • DO:
    • use the tool to verify network quality before purchasing One Talk service.
    • use the tool at any time post-implementation to troubleshoot call quality or device registration issues.
  • DON'T:
    • attempt to download the tool onto a mobile device (smartphone or tablet), as it requires you to download and run a 1.5 MB application on your desktop or laptop.
    • run the tool over a VPN connection, otherwise accuracy could be impacted.
  • See the One Talk FAQ page for more info.

  1. Qualification tests won't run if any of the following network ports aren't open and available:
    If any of these ports aren't open, the app will appear to freeze at the 'Testing' screen.
    For assistance with opening ports, contact your IT admin.

  1. To download the tool, visit the One Talk Site Qualification and Validation Tool download page.
    In case the link doesn't open in your browser, visit https://onetalk.visualware.com.
  2. Enter a value between 2 and 500 to simulate the number of One Talk devices to be used at your location.
    All devices connected to the network via Ethernet or using Wi-Fi must be counted, since all devices consume bandwidth from your internet connection.

  3. Click
    Start Assessment
     to begin the test.
    If this is your first time accessing the tool, a prompt advises you to download and run the app.
    The installation file is named 'bcs_service' and is located in your default download folder.

  4. After downloading the tool, click
    Run
     at the prompt to start the test.
    If you've downloaded the tool in the past, you can run the file from the folder where you downloaded it previously.

  1. Wait for installation to complete; the tool runs automatically and displays the following screen:
    Don't use other apps or refresh the screen while the tests are running. The duration of the test is directly related to the number of calls being simulated. On average, results are presented after about 3 minutes.

  2. Once tests complete, view the displayed results, which are categorized into 3 columns:
    • Capacity Results
      : This test confirms whether the number of specified devices can perform voice calls at the same time. A real-time bandwidth capacity test is also performed and a 'Max supported calls' value is presented which represents the maximum number of One Talk devices that can successfully make calls simultaneously over your internet connection. This value is of importance for determining whether or not you may have room for future expansion.
    • Network VoIP Statistics
      : This test conducts a real-time evaluation of your network conditions and provides a report on them. Four variables are reported on, and all are important factors in the performance of the One Talk service:
      • Jitter up/down
        : Some packets take longer to travel from one system to the other. Jitter values should always be under 5 milliseconds for optimal voice quality.
      • Packet loss up/down
        : When some pieces of data fail to reach their intended destination. For One Talk users, packet loss presents in the form of poor voice quality or noise on the line, amongst other things. This value should always be 0.1% or lower.
      • Connection latency
        : The time it takes for data to travel from the sender to the receiver and for the receiver to process that data and respond. Latency determines how fast the data can be transferred from the end point to the network and back. High latency creates bottlenecks in any network communication. It prevents the data from taking full advantage of the internet connection and effectively decreases communication bandwidth. The impact of latency on network bandwidth can be temporary or persistent, based on the source of the delays.
      • MOS up/down
        : Mean Opinion Score (MOS) gives VoIP testing a number value as an indication of the perceived voice quality after being transmitted and compressed using codecs. This measurement is the result of underlying network attributes that act upon data flow and is useful in predicting call quality. It is the best value in determining issues that can affect your One Talk voice service quality.
    • Required ports for One Talk
      : This test performs an analysis of the ports and protocols used by One Talk devices to determine whether the security devices (e.g., firewalls, etc.) protecting the business have been configured properly to allow One Talk devices to register, authenticate and provide service.
      • Ports used by One Talk desk phones
        :
        • 123
        • 443
        • 5061
      • Ports used by One Talk Mobile and Desktop Clients
        :
        • 143
        • 443
        • 444
        • 991
        • 5061
    Test results page
  3. View the summary table at bottom of the test results screen (example below).
    • This table is intended to be used as a reference for the results published by the tool to help the user understand them.
    • Results in green indicate that their One Talk devices will have a high-quality experience.
    • Results in yellow indicate that users may experience problems when making or receiving calls and voice quality could experience degradation. Because the codec used by One Talk devices (AMR-WB) is adaptive, it can make adjustments as needed in order to adapt to fluctuations in the quality of the internet connection.
    • Results in red indicate serious problems in the internet connection that require immediate attention. If items in the 'Required Ports for One Talk' section are red, proper analysis must be conducted to determine whether those blocked ports are relevant to the One Talk service (i.e., mobile and desktop app clients use ports that desk phones don't).

  4. If desired, from the bottom of the test results screen, re-run the test by clicking
    Run another test
    .
    Run as many tests as necessary to validate and verify your device deployment plan and troubleshoot any issues found.
  5. If troubleshooting with an agent, provide any yellow or red values to be included in a network ticket if one is opened.
