Yes, but only the Desktop Client: '3CX Phone for Windows'. We're working diligently on an integration for 3CX Server Side, but there's no set ETA as of yet.

    There are some common reasons why your Busylight with Cisco Jabber is faulty.

    • It's very important that you reboot your computer after installing the Busylight software for Cisco Jabber, so that the Busylight plug-in get loaded on start-up.
    • Make sure to close all other Busylight software than the Cisco Jabber software.
    • If you're running another App that uses the IM-interface for Windows, like Teams, you're going to have to change the Registry Entry for 'DefaultIMApp'. (Should be Teams as default)
    • Make sure that you've enabled client interface from the Cisco Jabber server side. Click here for a guide on how to do so.

    It's probably because you've connected your Zoom to Outlook.

    Zoom is sending us the notification “In a meeting”.
    As long as Zoom is connected to Outlook, this will happen.
    Unfortunately, we do not get any details about a meeting from the Zoom API, therefore, we cannot do something on the Busylight side.

    Yes it is. You can download it here.

    OBS: It is not as far along as the Windows version is, utility-wise. 

    Download the kuandoHUB here to utilize the platform priorities feature.

    If you're having issues with the 'Register MS Teams as default IM provider' prompt persistently closing your kuando busylight software, and inhibiting you from using your busylight product as you desire, it might be because your Office is faulty. You should go ahead and use the Office Repair Tool and run a 'Reset'. Here's how to do so:

    There are two ways to run a Repair. If you have the Microsoft Store version of Office, please follow this guide:

    • Right-click your Windows button and press 'Apps and Features'



    • In the next window, please scroll through your applications until you find 'Office'. Now press 'Advanced options', like so:



    • Then you're going to want to press 'Repair'.


    If you're running the Click-Once-Installer variant, please follow this guide:


    • Here is the ClickOnce variant:

    • Click on Modify

    • Select the Online Repair.

    If you reset the Busylight by unplugging and plugging it in again, you should see a sequence of primary colors being flashed in succession. If this is not the case, please try another USB-Port - also, make sure that the Busylight is plugged directly into the PC. If the sequence doesn't start then your Busylight is most likely defect.

    In the kuandoHUB, make sure that you've turned ON Calendar Reminders, In a Meeting state and Newmail Notification.

    You still need to have Skype for Business installed on your PC in order for the Office API to apply itself to the remaining Office applications.

    • Make sure the the bit-version of the Busylight software is the same as your Operating System
    • Make a Clean Sweep of your Busylight software and preferably of your local client software too (Teams App, Cisco Jabber Client etc)
    • Contact Plenom Support here

    If you're running Busylight for MS Teams 2.X or above, then more information is needed to determine where the issue lies, contact support here.

    If you're running Busylight for MS Teams 1.5.7 or below, then it's because Microsoft hasn't updated their API for Teams Call Events, so we can't program a software integration for that feature. However, we do have a workaround for this for the people using Plantronics headsets. Click here for the guide.


    • You have to check a box under settings in MS Teams to register it as the default messaging app for Office.
    • When you download Busylight for Teams, remember to install the correct bit version for your Office installation. (32-bit or 64-bit)
    • If nothing works, you could try installing our Team Graph API software for the Busylight. It runs separately from Office.

    There are a few ways to see if minor faults are easily fixed. These faults can occur if the Busylight has been running for a while or if many new variable are introduced into the Busylight environment. You could try some of these methods:

    • Reset the Busylight presence by right-clicking the appropriate Busylight icon and press 'Reset'.

    • Check to see if there's a new version of your software available from here.
    • A good old fashioned reboot of your PC could do wonders.
    • If you've recently started using another softphone with Busylight (1< total), you need to use the kuandoHUB to prioritize platforms. Get it here.
    • If you're migrating from Skype for Business and you've recently uninstalled the application, this is probably why. Skype for Business needs to be installed on your PC, as a major part of the Presence API for Office lies within S4B. It doesn't need to be running, but it has to be installed.
    • If there's no easily apparent solution to your issue within the FAQ, please contact Plenom Support here.

    If the meeting is scheduled in your Calendar Events from ex. 08:00-09:30, the Busylight will stay red for the entire duration of the Calendar Event, unless you manually change your status in Teams. If you leave your meeting early, the busylight will continue to display your presence as being in a meeting. This happens because Microsoft Teams mirrors your Outlook calendar and since the meeting isn't over yet (at least not for everyone), your busylight will continue to stay busy.

    There is a broad selection of Premium Busylight software to choose from, find the one(s) you need by clicking here.

    You could be in a situation where our Premium Busylight software isn't what you're looking for, but chances are the software you need has been developed by a 3rd party. Check out all the Busylight compatible platforms here.

    Yes. Cisco WebEx is now a supported Premium Busylight software for Windows. Find it here.

    If you are installing Kuando Busylight UC in a Citrix or VMware environment, here are some articles to help you redirect USB devices:

    Please note: Citrix XenApp 7.6 has the necessary redirection of USB devices to run Busylight. However, we have no documented support for XenApp 6.5 due to missing option to redirect USB devices (more info on USB redirection).

    Yes, but only for your Google Calendar.

    Naturally we want to extend compatibility to Google Meet, but that is not possible for now since the API for Google Meet either isn't available or sufficient.

    Please note: Busylight won't start if there no compatible Microsoft Lync or Skype4B client installed.

    Skype for Business 2016 – One common error If Busylight does not start or function correctly after Office was installed or updated (and some cases removed), it’s typically because some registry values got messed up - in particular when upgrading to Office 2016/Office365 x64. Please keep this in mind when choosing x32 over x64 of Office. Running a repair on your Microsoft Office will typically fix the broken registry entries: Go to Control panel > Programs and features > Rightclick your Microsoft Office product > Select repair > Choose Online Repair if asked and follow the guide.

    Run your Command Prompt as administrator. You can search for it in the Windows Search Bar as 'cmd'. Inside, type in these commands: mkdir \temp (this creates a new folder named 'temp') cd \temp (this prepares the folder to receive a log-file) You can find the c:\temp folder by simply using copy/paste and inserting 'c:\temp' into the search bar of your file explorer. Now copy/drag the Busylight software .msi file into the c:\temp directory using file explorer. Now type this command in the same Command Prompt msiexec /i "NAME OF INSTALLATION FILE" /L*v "setuplog.log" Once you've done this, the installation should run through its process. Whatever happens during the installation process (successful, crash, missing plug-in, etc), a setup log-file will appear in the c:\temp folder.

    If you just did an install of Busylight for Cisco Jabber it is likely you will have to exit Cisco Jabber and Busylight completely and then try to relaunch both again.

    Busylight UC for Cisco Jabber requires .Net 4. Not every Windows has this preinstalled. If you don’t have it installed, download .Net 4.6.1 here.
    When you know you are running the correct version of .Net 4 but still having problems, please try a repair of .Net 4.x.
    Still no luck: please contact us via the contact form or write us at [email protected]
    Yes, Busylight is compatible with Skype for Business, but not the free version of Skype (for consumers). Skype is, however, approaching its end of life soon and Microsoft intends to replace it with Teams as their default communications platform.

    Yes, Busylight is compatible with Cisco Jabber version 11 and above.

    Yes. Our newest release for the Microsoft Teams integration is compatible with both Call Events and Presence, 
    but if you're running an earlier version of our Teams software, you're going to need a work-around for Call Events.
    (incoming calls, outgoing calls and IM)
    It requires a Plantronics headset and the PlantronicsHUB to work.
    Here's a guide on how set it up: MS Teams Call Events Workaround

    For multiple reasons:

    • If you're using more than one platform frequently and simultaneously, then you need the kuandoHUB to prioritize which platform(s) dictate the presence of your Busylight.
    • The kuandoHUB is a very handy tool in optimizing your workflow, with Hotkeys, kuandoTIMER, Outlook Options and much more.
    • In general, it makes your Busylight more customizable

    Yes, if you register your software, we will inform you of updates that you can download free of charge.

    The colors are mere reflections of your presence states on your platforms of choice. But you could say that the defaults are:
    • Red: Busy
    • Green: Available
    • Yellow: Away

    Combinations of MS Teams, Cisco Jabber and Webex are currently not supported by kuandoHUB

    They work like shortcuts for the Manual Color Changer. Ex 'CTRL-5' could configured to set the color of your Busylight to Red, making it easier to leave your computer in a hurry if you have pressing matters elsewhere.

    If a user is experiencing issues with kuandoBOX please ensure the user:
    1. does not have both Lync 2010 AND Lync 2013 clients installed on the same PC.
    2. is not running an outdated version of Lync 2010/2013 (see list of updates for Lync 2010 and Lync 2013).

    The kuando TIMER supports your personal time management. The underlying idea is for better efficiency by having the tasks and breaks organized in a scheduled work/break structure. The default values are commonly used to ensure a good balance.

    The kuandoBOX only allows you to connect either your headset or your handset.

    On software version 2.0+ we are using DebugView from Microsoft to log software issues. Please ensure that DebugView is running when you start the Busylight/ KuandoBOX application to log the start-up sequence as well.

    1. Download DebugView by clicking here
    2. Close Busylight software
    3. Start DebugView
    4. Start Busylight software
    5. Reproduce the issue you're experiencing
    6. Close Busylight again
    7. Save the log file

    You can pick and choose which platform(s) is going to dictate the presence state of your Busylight. Using the arrows on the right-hand side of the interface, you can move all of your platforms up and down the priority hierarchy.

    No, sorry.

    1. Check installation(see installation guide)
    2. The two selection switches on the side of the Busylight box have the factory setting "I". Move them both to "II" and check if the problem is solved.

    The Busylight lamp fades out, when there is a pause in the conversation and when the call is terminated. You can adjust how long the pause can last, before the lamp fades out. In position "0" the light goes out after 3,5 seconds. Every step (0-9) increases the interval by 2 seconds.

    Adjust sensitivity. 

    The Busylight box has a manual switch for a blue light. This is designed to be a Do Not Disturb indicator. If this switch is activated, it will override the red light for headset activity. Please turn off the blue light to see the automatic red light for headset conversation.
